Hi fellow reefers
I'm quite new to this forum and the marine hobby, have been running a 2x1x1ft tank for about 6 months now and only starting stocking recently.. Currently have 2 maroon clownfish(yes they fight.. ), 2 azure damsels and a BTA. My question is whether I need a sump, and if I do, what do I need to build a sump? plumbing, overflow etc.. I do have small spare tank. A rough cost estimate would be useful too
Because I had a huge problem with nitrates before I did a major water change.
My ammonia and nitrites are zero, nitrates are about 20ppm, currently running on a HOB filter.
Thanks in advance
