A local chap is selling some lights as he is tearing down his system. This is what he is selling: 2 160 kessils and 2 Red Sea 90 leds. I have one 12g cube in my office that is currently just FOWLR. I am gaining the confidence to get into corals. Still studying. But the first ones will probably...

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...

Hi. My Aquarium is been set and running on the FOWLR for the last two months. I have a UV sterilizer installed along with all the other essential equipment however I’m skeptical on using UV because I’ve read mixed reviews about it. What’s your take on using UV sterilization? (If yay, how long...

Hello there! We’ve got a 125 gal mixed reef with fish aquarium 72Lx25Hx18W. Would these lights be beneficial? VIPARSPECTRA Timer Control Dimmable 165W 300W LED Aquarium Light Full Spectrum for Grow Coral Reef Marine Fish Tank LPS/SPS currently running two Kessil A80 BlueTuna

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?

What is the best? (in your opinion) Entirely subjective reasons allowed on this totally precise poll

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...

Hi i was just wondering what everyone’s opinions are on leopard wrasses? i want to get one, which one is the easiest to take care of and isn’t as sensitive?

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...

Hey, everyone. I am BRAND NEW to the hobby. So new in fact I currently don’t even have my first saltwater tank. However, I plan on starting that up this week. Since I’ve watched 100% of Mark Callahan’s videos on setting up tanks for beginners, I feel confident that my first tank will be a...

I want to know your spectrum and schedule regardless of what kind of light you have. If you can give all the details, spectrum, schedule, intensity and your results that would be great! I am currently running a Radion XR30w g4 PRO on the ab+ setting. I swear I was getting better growth using...

Hello, I have been looking to add a Kole Tang to my 90 gallon and I have notice that some of the Kole tangs that I have seen have either been brown or purple in color. Can anyone explain to me this difference and how I could order a kole tang so that it will specifically be more on the purple...
