hob refugium

I have an aquaclear hob converted into a Refugium. In the chamber before the chaeto, it is the water pump with constant flow, flowing through the grated plastic barrier separating the 2 chambers. I assume it is ok to run filter floss in this portion? I haven’t noticed any copepods in that area...

My most updated shot of the tank: Updated - April 5th, 2026 Origin story! Hello! My name is Andres and this will be a progress journal of my first ever saltwater aquarium! I am brand new to the hobby when an opportunity arose from a colleague to inherit their saltwater tank as they had to...

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...

I bought this small CPR HOB Refugium from Aquacave. https://www.aquacave.com/aqua-fuge-2-hang-on-refugium-small-by-cpr-aquatic.html I had read awesome reviews about these guys and thought I'd try it out on my JBJ 45, but now reading I'm wondering if I got too small of a size? My ultimate goal...

Curious if this would work, if not, I could use recommendations on clip on or magnetic refugium light. Here's the refugium I have: https://www.marinedepot.com/cpr-aquafuge2-hang-on-refugium-small I came across this small light Finnex light and curious if this would work...

Any recommendations on a decent HOB Refugium that isn't too big for a 45g tank? I'm new to these, so not sure what all I need other than a grow light and the refugium.

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!
