So, i've decided to build my own sump instead of using a canister on my 30g bw GSP tank. I almost have everything I need, just a few questions before I start:
All the plans I have seen include a refugium, but I don't really understand what I am suppose to do. Obviously I won't have much plant life with a BW tank, and because I'm going from FW -> BW, there won't be much life during the transformation, so should I just skip the refugium part and use something else? I'm drawing up my plans right now, so if anyone has any suggestions (or pictures) please share them with me
Also, do I need a protein skimmer? I've read theyre mainly for SW tanks, but every sump plan has also included one.
