Hi sorry for a totally newbie question but I purchased a full setup used that was meant to include live rock that had various corals attached. Sadly they broke the tank down a few days before delivering it to me so I am assuming all the corals died despite them saying they will “be fine in the...

Well, here I am. The prototypical cautionary tale: I bought this tank with big dreams and genuine interest, but because multiple life reasons and changes, it has been sitting in the garage since I picked it up in late 2018. Finally, I'm now relocating so I can't put this off any longer. I have...

good or bad? is there anything to be mindful of? any species that could be effected? so on and so forth.

What it says in the title, what is the NUMBER ONE easiest coral to keep? In accordance to hardiness and maybe beauty!

Hi all, I am planning on upgrading my saltwater aquarium to a 150L here in August. I am looking at creating a undertank sump system, as I have a spare 20L that is just sitting around. What all would I need to start the system? Links to everything, please? I have about $400 available for use...

Hello everyone! I am 3 weeks into my 55 gallon tank cycle and I just moved my over the tank filter to move it the right a little bit and out flew all this white fluffy/stringy stuff and it’s all over my tank! Is this good bacteria or is this bad? I just added two Clownfish in today. Salinity -...

Hi everyone. I recently started a 40 gallon breeder and it was going fantastic. My corals were doing great as well. Then it all went downhill and even my torch died which was heartbreaking. I use an AI Prime light with a self made all in one with filter floss, filter sponge, the balls for...

I’m a beginner to marine and look forward to learning and enjoying the hobby. I have kept cold water and tropical for many years, this is the first time I’m doing saltwater. I feel like a bit of a cheat on the build thread as the tank has been going for a little over 3 weeks now. Setup Fluval...

My 300 gallon / 1.100 liter drop-off display tank was in the living room, and now we remodeled the house and ended in the hall. Allowing a complete restart. Despite losing the peninsula feel, where the tank was initially build for, I do think the new place is ok, And now 4 months running and...
