3D Printed Reef Gear

Hi guys, I figured I would post here and share some of the creations I have put together and printed to see if anyone is interested. I 3D print everything in reef safe ABS or PETG and soak in rodi overnight before selling. I am able to customize any and all of the items and even create custom pieces for you. Some examples include media racks, light shades, frag racks of all shapes and sizes, heads and other items for encrusting corals, frag containers, frag plugs, frag trees, you name it! The picture shows some of the pieces I’ve made, the transport container can be customized to your liking as well (words, logos, etc). I am based in Orlando and we could work out shipping if interested. Thanks!

Help! High nitrates with canister filter.

I have 55 gallon saltwater tank. I have five fish a shrimp and a sea star. I also have five beginner corals. I test my water weekly and I suddenly have high nitrate levels. I have the Aqueon 300 canister filter. I have already done two water 15 gallon water changes with really no change. I am scared of losing my fish or corals. Any advice would be greatly appreciated

Looking for a fourth fish

Currently have two O. Clowns and a yellow Watchman Goby in my 26 gallon tank. I think I want to add one more fish but I’m not too sure what. I want something with good personality, as my current fish do almost nothing. The Goby only comes out to eat and the clowns just hangout. I kind of want something that will stir the sand some, but I think another type of Goby is a bad idea. It’s a mixed reef with lots of inverts.

Diatom question

I've had a tank up and running since January. I only use rodi water from my aquarium store.

I've had diatoms for the past few weeks keep coming back.

Is this normal? Anything to do with over feeding, etc? Or just let it run its course? More water changes needed?

Copperband Butterfly

So I've been battling getting my CBB comfortable and eating correctly. I noticed he was swimming in a pattern on the glass, so I decided to see what he was doing this morning when lights were out and he was grazing and not doing the pattern. What's going on there?

Any techniques or food ideas?

I've picked up ROE and arcti pods to try today. Have tried mixtures of mysis, brine, krill, calanarus, food feasts. He ate abit the day after I acclimated him but I haven't seen him eat much since, I've also added a crap ton of tisbe and tigger pods to my sump and display. Even been placing nori. I should have a feeder I designed and printed today to try as well.

Dino on Coral?

Hello,

I just purchased this coral about two weeks ago and noticed that it is starting to die off. Does anyone know what is causing this and a solution? Looks like Dino but no quite sure,

I have a rock about 7" dia with monti. digitata and monti. hirsuta started on it. If I add an encrusting monti to fill in, would it kill the 2 branching types, or just stop when they contact?

or other recs to cover the rock?

Bleached?

I'm pretty sure he was purple before I went to sleep and this morning totally white. Someone gave me this frag and I'm not sure what it's called. I placed him at the bottom of tank. Low flow and and I thought low light. Any thoughts?

What is this?!

Does anyone know what these little white things are on the rocks? A long worm like thing comes out of them and goes back in.

Any recommendations for an acclimation box/ideas? 1.25" thick acrylic

I am looking for recommendations for an acclimation box/ideas for my tank. The acrylic is 1.25" thick and this has been painful when it comes to sourcing a box.

At this stage, I am going to buy a nano reef tank and use it as an acclimation box but want to avoid spending on a new tank (albeit drastically less than my DT).

Need advice

Took this guy in last night from someone who had a tank leak when I got home noticed he’s missing his fins and body has some patches missing.

He was in a bucket with rocks not sure if he scratched himself there but that doesn’t explain the fins missing.

Any suggestions what to do and will he recover ?

Question about cycling

Yesterday began my journey into my first-ever tank reef so about exactly 1 day after setting up my live rock, live sand, throwing in some turbostart to begin cycling my 15 gallon tank, I realized that my water heater wasn't setup correctly and the entire tank has been cycling at around ~66 deg F for about 28 hours. So I was just curious, just how screwed I am if at all and what my course of action should be? I have now correctly setup the heater and will proceed with the standard cycling procedure from here on out until I hear or read otherwise.

Help, is my clownfish alright?

Parameters: Ammonia - 0 Nitrites - 0 Nitrates - 15

Tank has been up for about 6 weeks. Pair of clowns were put in about 2 weeks ago. Little male is a beast always swimming around and eating but big female has barely eaten since I got her. Lfs advised me to treat w prazipro and try feeding with live brine shrimp (ab 1 week ago) past 2 days she’s only been at the bottom breathing pretty heavily and hasn’t eaten as far as I’ve seen. I dosed prazipro again today. Any advice/help?

Symptoms: not eating, white long poop, heavy breathing, staying at the bottom corner (still active)

Treatments so far: prazipro for 1 week 2 doses water change 3 days after initial dose.

rescaping tips and help

my tank has been running for 4 months now. i’m not necessarily unhappy with its looks but, im unhappy with the difficulty of getting in there and moving shit around when i need to. also some of the rock is against the back wall which,again, just makes it a pain in the ass to do maintenance on. i guess the question here is how do i go about rescaping? i first thought just get bins put everything in the bins and rescape but am concerned about my nems and some zoa colonies that are more grown in. any tips or pointers appreciated. thanks

Tank cleaning, vermetid snails.

Clogging in a drain overflow drain pipe. Pipe is about 2 inches in diameter and runs about 16 feet down the back of the tank and then back into the sump. Typically would recommend a temporary breakdown of the drain pipes and clean manually. Unfortunately the tank drains go through the wall and was not installed to be accessed. Thoughts on this drain snake for knocking out the snails. They have grown to cover the inside of the pipes to about a 1” drain now… water all on the ground.
