its funny you say that but i made sure to add a little extra prime because i just recieved the kerri tetras from h1n(len) and one of them got a little roughed up in the shipping so the api conditioner states to add 5ml extra per capful for fin repair.......
so i know i added it...plus the fertz.....and i checked my water parameters 2 hours later before i went to bed and they were good...
i am running a 4 stage jebo canister and a 700gph canister(i forget the brand)
this tank has been established for 4 or 5 months now ??
the only think i can think of is (tell me if im way wrong or not) i have been noticing that my plants arnt doing as well as they should be with 2 wpg and all the fertz im doing, so i was thinking that my 110 watt compact flo doesnt have enough PAR for my 50 gall tall its 30 inch's tall ....so can the plants be soaking up the oxygen in the water during the night but not letting enough out in during the day??
