Looking for a new tank with uncommon dimensions
Hi yall. I’m looking for a rimless tank that is 48” by 30” deep and 18” tall. Not looking for specifically a pre drilled option, I’m fine doing all the plumbing and such myself. I just can’t manage to find any options fitting my criteria.

New Tank - Cycling Advice
PFA! For context, I’ve been running a 20Gal/75L nano tank for the last couple of years, and have just finished setting up my new 185Gal/700L tank (scape is in, wet, salted, and I’ve just starting cycling with Dr Tim’s One and Only, adding Ammonium Chloride up to around 1ppm)
I’ve come across a number of posts recently suggesting that ammonia doesn’t affect corals in the same way it does live stock, with many people adding corals during the cycle stage.
My question being, I have a large Neon Green Cabbage Leather sat on a single small/medium sized piece of rock in my existing nano tank, and I’ve also got a Mushroom sat on a very small piece of rock - Is there any benefit in moving either/or both corals/rocks over to my new tank, mid cycle, to speed up the cycling process? Or am I better off sitting tight, and letting the cycle complete over the next few weeks, before moving anything over?

Don’t want to hurt feelings…
Hello,
My friend gave me some free corals - really sweet - but it’s crawling with aiptasia, bristle worms, various pest algae and who knows what else - I did a coral rx dip but I just spent 200+ dollars on some new corals in my QT tank - I QT everything and my friend doesn’t - I don’t know what to do - the corals don’t look in very good health, dull colors - I feel like a huge jerk but I spend so many long hours QTing everything and carefully stocking my DT tank - what should I do?

Cycle new tank?
I have a 15g reef tank that has been going for like 3 months, I got a 30g tank as a gift and want to move everything from the 15g to the 30g, would I need ti cycle it or could I just move all the sand, rocks, filter and water to the new tank? Wouldn’t that count like a 50% water change? Or am I misunderstanding?

Light Recommendations
Hi all! I've had a fluval sea evo for about a year and would like to buy a better light now instead of the one it came with. I'm looking for something that will fit the size of the tank nicely but has more options for controlling the lighting and will be better for my corals. I only have soft and LPS corals, so I don't need anything super powerful. Looking forward to hearing your recommendations!

Thanx in advance, Mert

Clownfish advice
So I pulled one of my clowns out of quarantine a little early because he wasn’t doing well. I suspected and saw the other clown who’s much bigger pick and nip at him. He had quit eating for about two days and got kinda thin. He ending up getting really slow and sat sideways on the bottom of the QT tank for a couple seconds without even moving a fin. I ended up pulling him out and doing a 5 minute freshwater dip and acclimating him to my display and putting him in. He seems to be doing better already even after two hours or so since separating. I wanted to see if yall see anything visually odd. I know pulling a fish from quarantine early is definitely not ideal, but he doesn’t and never did seem to show any signs of illnesses. Would copper power (what I used in QT) have a greater effect on smaller fish? Or was he just getting bullied?

GSP advise
Did I glue it correctly? Will it grow over this whole rock? I see the edges are kind of growing back on itself, is this normal? Will it correct itself? Should I glue the edges down? Thanks!

Is this stuff supposed to smell? I have heard Turbo Start smells like rotten eggs. This didn’t have much of a smell at all.

Bought this hammer a year ago as a 2 head and it sprouted another and practically doubled in size. Is this good growth? How can I get it to grow faster? Pretty euphyllia!!!!

Radiant Wrasse Help
Just got home from a few days away from my tank and noticed my radiant wrasse swimming weirdly near the top of the tank and is only using her pectoral fins. Could she have a spinal injury/broken back? She doesn’t look right to me. Any advice/input would be greatly appreciated.
