I have a JBJ 45 as well , it s been 3 weeks of cycle ,I recently added 2 chromies ,so far so good , I added a eshopps nano skimmer , tunze ato , 1 wavemaker (I m adding one more for more flow behind rocks ) and I also ordered 2 intank media baskets 14" height 4" depth 4" width , (still waiting for them ) one of them is for a refugium with some ceramic biomedia balls , also still thinking about adding a carbon reactor or a biopellets not sure yet ... I hope all this equipments adding to that little sump keep water clean ,also water changes periodically .... I ll post pics when I set everything up ...
