I have a small 100 gallon “pond” in my yard. It has been there for over 4 years. I have a few good size goldfish and a handful of minnows.

It has a been stable and healthy for years. It draws stray cats but I build barriers and the fish have hides and keep away from the edges (understandably). I checked on them Thursday afternoon and all was well.

Saturday morning everything but one of the smaller goldfish and one minnow is gone. There are no carcasses laying around. The pond equipment is in order. Nothing that indicates a fish massacre happened. I live in Washington DC.

What is your best guess? A large bird, a raccoon (I have never seen either at my pond)? It could obviously be a cat but I thought I would see a big mess if they jumped in and started pulling out the bigger goldfish - wouldn’t I?

Dug a new pond (blue one) and connected a tunnel to the old one. Time for some koi!

We bought one of these pumps and the salesman said it's also a filter but after owning it s year, it definitely is not.

We have a 100 gallon stock tank. Can I use any of these options?

• https://a.co/d/fwJ05pY - stick these in the pump cage?
• https://a.co/d/0FLZIpF - maybe this could go in the pump cage?
• https://a.co/d/bqihheI - I could push water from the pump through the opening on this. It's intended for water to flow the other direction but might work

It's not a large pond and prefer not adding something that sits outside of it. Also prefer not plugging in another device that uses electricity.

I have a 2 acre pond in MA, a dammed brook, feeding into a river. I can’t find a company that will deliver stock fish this far north. Does anyone know any companies that deliver up here? I’ve tried the state agencies already. The state stocks trout in the brook well upstream from me but that’s all.

Anyone know what these are? They are stuck to the waterfall and rocks.

Just as the title states. I have a 450 gal pond with 7 goldfish about 8-10 inches in length and a bunch of rosey red minnows. I inherited them with a new house and wondering how often and how much to feed them?

Edit: spelling

I’m starting a pond as a water source for birds in my backyard, but will have plants in the summer. Will a pump work all year? Do I need filter if I don’t need the water to be super clear? What about none and just a deicer in the winter? Location is Maryland, USDA zone 6b.

Hi!

Long time have wanted to build a pond. Would honestly prefer a dug out one but with small children I feel that's too much of a safety hazard. Instead I'd like to construct an above ground pond.

Our backyard is currenty unfinished so we are planning on building a patio back there, and hope that the pond can "match" the patio pavers we would install. Ideally pond would be rougly 8-10' long, 4' wide, and 3' high (so hold 700-1000 gallons). Likely will plan to put a metal grate on top of it for safety purposes. I'd also like it to have a viewing window so kiddos can actually enjoy it.

I've seen a few posts over the internet and reddit on how to construct this. I feel I'm down to two options but want to see if there are any others:

1. Buy something like this:

https://pentairaes.com/fiberglass-tanks-with-window?srsltid=AfmBOoopWQXkTFHBhT-Cmes6BnuzHdouVifC1-uuw5Ve9ZtA1GQFSRG-

and simply stack pavers around it to make it look nice. Main issue with this is that the fiberglass is expensive and reading some reviews about this company online, it seems that the glass is low-quality and they are mostly used as large holding tanks.

2. Construct pond out of cinderblock, steps below:

A. Clear ground and place level concrete foundation. Would probably hire someone to do this and DIY the rest of the steps. The ground is uneven and has some old tree roots...

B. stack cinderblocks around to make tank, filling with rebar and concrete

C.for glass/acrylic panel, would probably have to buy something like this https://www.spieringsvis.nl/889-frames-en-ramen and find a pane of acrylic or glass. Does anyone have suggestions in the US?

D. Liner inside tank

E. Somehow make the outside look nice, either by stacking pavers on the outside or placing panels that match the patio pavers around the outside

F. Making the inside look nice? A bare black liner seems like it would look ugly. I suppose less important priority, could decorate with some scattered rocks.

Questions:

-Filter: Bottom drain is too complicated. I could build in a pipe on the side of the tank that could house some type of filtration. Any experience with this?

-Constructing this: Am assuming concrete filled cinderblock with rebar is a good choice for this. I've seen it done w/ wood but worry about rotting and also about aesthetics.

-attaching to foundation: Let's say I have someone come in and place a level concrete slab. What is the best way to "attach" the tank to this? Do I drill the rebar into the concrete? Mortar to the concrete?

Hi! I have a slow leak in my poly plastic lined pond. Apart from letting it drain out to see where it’s leaking, are there any clever tips from any of you?

In Australia if it makes any difference.

About a week ago I had a major pond failure that resulted in the lose of almost all of the water overnight from my mature 5k litre garden pond.

I saved all my koi and they are now doing well in a temporary tank however my established breeding school of about 60 European Minnows are all dead. (I got them into a separate tank but the stress was too much)

I'm in the process of repairing and refilling the pond and will be looking to replace the minnows however I was wondering if people had any suggestions for a similar sized fish who's job it was to eat larva but might be a little more colourful?

i finally put together a pond this spring. i tried keeping a common yellow water lily (along with several other plants) in it. the water lily was doing well for a while (actually grew a lot of leaves and seemed happy) but completely died in september. the leaves just rotted away and it stopped producing new ones. i had it in aquarium aqua soil. it got full sun to start, and as summer went on it became shadier. just need some tips because i do want to try again next year! i know the basics of how to overwinter in minnesota but i have to get one to survive the summer first 😅 obligatory picture of at it’s happiest in july. in september raccoons repeatedly came and ate my water hyacinth, grapes, and arrowhead plant and i think they took a few nibbles of the water lily too- and the fall leaves kind of smothered the pond.

Woke up to the shock of my life when I saw all 6 of my lemon tail barbs floating on the water. They have been living fine for over a year now. The rest of the fish(pleco, tilapia, catfish, other species of barbs, gourami, koi) are all going about their day.

The only thing I did yesterday of note was use a pump to vacuum out months worth of accumulated waste at the corners of the pond. However, these yellow tails aren't frequent bottom feeders and other fish like koi, tilapia, and the plecos also rummage through the sediment but didn't die.

Does anyone use diatomaceous earth for filtration?

I live in the Phoenix, AZ (USA) area where we get 1/3 of the year with temps in the 110s and the rest of the year is usually moderate temperatures. This is my first year with my pond- about 1200 gallons- max is about 3' deep. I have a waterfall with filtration and bubbler aeration. I also have 7 large goldfish and 1 red eared slider.

I'm really looking for some direction now that the weather is cooler and the water temp around 55F.

1. Should I turn off my waterfall in the winter? Put it on a day/night timer and run only during the day?

2. I'm really concerned about my turtle. I'll post in the RES sub too but wondered if anyone in this area/climate lets their RES winter in their pond. He is currently in there and I added a container where he can brumate but I'm still concerned he's getting too cold- just need some reassurance that he will be fine.

3. Any other advice for my plants (water lettuce, lilies, etc.) and fish for the winter?

I really appreciate any advice. I have scoured the sub and google but I'm not feeling like I'm getting responses that are specific enough to this crazy climate. It's not going to freeze here, but the water temps will still get low enough to be concerning for my turtle. Thanks all!

So I'm wanting to possibly set up a 300g and 150g stock tank in my garage for my turtles, I want to minimize or completely remove the need for water changes so I was wondering If its even possible to set up a bog filter indoor to remove nitrates.

Anyone know if this is even possible? and if so any advice on setting it up. I have plenty of time to try and figure it out as my turtles still aren't big enough that they require bigger space.

Any advice would be greatly appreciated.

Hello pond gurus! I'm planning on building my wife a fish pond in the next couple weeks and thought I might get your opinions on some aspects. I live in Northern California, where the summers are somewhat hot (105-110 on the worst days) and the winters are mild (maybe low 50s?).

Here's the stock tank I plan on using (or similar, I haven't quite decided what size I want to go with yet). I'll save you a click, it's a 3x8x2 galvanized steel tank.

I plan on using Pond Armor to seal the inside, and maybe give it a nicer "pond" look (color suggestions welcome!).

What I need help with is figuring out the rest. I want to get her some gold fish and maybe some bottom feeders or something to help keep the pond clear - we built an in-ground pond at my in-laws that refuses to stay clear despite our best efforts, and I'd like ours to stay semi-clear.

I plan to throw a couple of cinder blocks in the tank for the fish to hide from predators, but I know raccoons and cats are plentiful here so what are some options for netting that won't block my wife's view of the fish, or are easily removable?

Finally, she loves pond plants but I haven't the faintest clue where to start on that. Any and all suggestions welcome here.

Show me what you got r/ponds.

I live in the Northeast US. I moved to winter mix and one time daily feeding per day back in early October due to the colder overnights. But there are days we hit the 70’s and my water is in the mid 60s.

What are you doing?

I dug this pond. It’s about 10x15 and 3ft at its deepest point. Plants are mostly in submerged pots. Wondering if there are pro or con to putting a layer of sand at the bottom? Thoughts?

I have a small 1/4 acre pond. Center is 15’ deep. It has a lot of perch all sizes. It has 2 aerators set on timers to run 10 hours a day that I run all through winter without problem. There was also a separate well from the house, (you can see it in the picture in line with the fountain) when I bought it. I decided to run a fountain off it, which I used pvc pipe, and then converted to a 2” discharge style hose connected to the fountain. It doesn’t recirculate, I just run the pump. I’ve actually ran it for a week straight 24/7 if the water gets low. 2 questions; Can I just run that pump for days or weeks on end without anything bad happening, other than the cost of around $20 per day in electricity. And also, what are my best chances for that pvc pipe not freezing?

I just bought a home in central MI, the pond is about .5 acres give or take. Overall depth looks to be around 10-15 feet. When I first viewed the home in September the water was about mid way up. Now the water is almost completely gone and fish are dying. The pond does not have a liner and the bottom doesn't seem to be hard clay. What should I do/ who should I contact to have it fixed/ able to hold water? Thanks in advance!
