Hi all, I am currently looking to start adding some corals to my 20 gallon cube tank, but I am wondering if I should rearrange my aquascape first. The bottom half of my aquascape mostly has shaded or vertical regions where it is making me second guess my design. I really like my cave, maybe...

This is my first time ever building an aquascape and was not I wondering if I could get opinions on it? It's going in a 25 gallon lagoon so I tried to keep it more of a wide scape than a tall one. Thanks!

Hello, I am starting to plan an aquascape for a 112 gallon red sea 525 XL tank. This is my first reek tank. I am planning to get a mixed tank with SPS at the top and some LPS at the bottom. Those are the things I tried to think about: I tried to consider flow by keeping enough space between...

So I started about 6 months ago with a basic 10 gallon and 2 clowns. I decided to upgrade and found a used 20 gallon IM fusion nuvo with the AIO taken out and upgraded to have a sump with an overflow. Ive been running that tank for about 2-3 months and its making me not enjoy it as much based on...

I went with AF Rock -- very heavy on plates and shelves. This is good for my shallow 5ft 100G tank. Except for the two bases, All the other rocks are suspended (i.e. overhangs and the like). Looking for honest, constructive, non-hurtful criticism, and opinions. Is this supposedly minimalistic?

Now to start don't get me wrong I believe first comes husbandry. But I've been doing a lot of research recently about Kelvin with reef lights, and I'm curious to see what other reefers use for their reef tanks. I'd like to know if you have found any differences between 10k vs 14k to even 20k...

Happy Friday everyone.... Hoping to get some more experienced opinions here. As I often do during the day, take a 10 minute break to watch my tank. Noticed my anemone starting to what looks like a second mouth, or perhaps just the way it is wedged in the rock at the moment. Thought I'd take...

Opinions needed please. In one of my tanks I am currently using crushed corals for the substrate. That tank is not even a year old yet, it is fully cycled though and already has fish and all sorts of inverts thriving. I would like to switch out the crushed coral and replace with sand. Nothing...
