hob refugium

20G Red Sea max Nano AIO tank is currently 4 months old and is still going through ugly brown algae phase. I am currently using brightwells xport no3 and biocubes to keep nitrite and nitrates under control, as the tank is overstocked. Fish seem happy and healthy, and water parameters seem fine...

Hello , I am returning to the hobby after a 10 year break. I am doing a small 36 gallon with soft corals and live rock and maybe 4 or 5 fish. My last tank I had a 55 gallon FOWLER with a canister and had no issues. However after reading this site I have learned that canister filters are no...

Hey Everyone, First I wanted to say how informative and helpful this community has been as I've taken my first steps into the saltwater side of the hobby! Second, hoping to get some guidance on my set up. It's a 20g high and I modded an Aquaclear 70 HOB into my refugium. Its been working...

Title says it all! Looking for a nice HOB refugium, preferably nothing too big, it's going on the back of a 45g. Also looking for an IceCap Gyre preferably the 1k, but also interested in the newer 2k. Let me know what you have!

This is obviously my opinion but works great for me and I would recommend this setup to anyone. I’m using a Fluval 50 but I feel like this can work in any HOB filter. The media need is: • Cheato •Filter floss •Poly filter pad •GFO/ chemi pure blue nano •LOTS of bio blocks/pellets/spheres This...
