I need a second opinion on the advice that I am getting from someone on the Reef Tank site.
My problem started just before Christmas. All my water tests have been off. I have a 110g reef tank with approx 200 lbs of live rock. I am using the Fluval FX5 canister filter. 2 power heads, Coraline protein skimmer and Coraline 9 w UV
My biggest problem is with my nitrates. They are around 250 ppm
. My daughter works in a waste water treatment plant had has taken water samples in for testing. The first set of results came yesterday.
I'm hoping that I get the rest of the results later today.
I was using tap water for WC
and top ups adding a little prime each time. So with this problem I installed a 5 filter RO
system. I have done several WC
's since the end of Dec one being a 50% change. I did another WC
yesterday. No luck the nitrates are still off the chart. I've python-ed the sand bed each time. The sand bed is about 1 1/2 in depth.
The advice from the other site is that I should get rid of my canister filter. I wondered if anyone else agreed with this.
