I currently have an ugf
in my 90 FO
. The substrate is cc
and sand. Here's the question. I have a tetratec 500 hob
filter which has a wet/dry action on it. I have no LR
and don't plan on getting any because this will be an aggressive only tank. My nitrates stay around 15 to 20 even though I change the water every week. Should I keep the ugf
or not, and if not would it be alright to leave the trays in and just remove the uptakes and air pumps. I do not have any powerheads or a skimmer in this tank. However, for those who don't know the tetratec, it has a portion that has foam and is constantly cycled out with air then water to get maximum oxygen to the bacteria.
