Filtration...when is enough enough

[Alex T.]

With the advent of carbon dosing and gfo into the hobby, it appears (correct me if I'm wrong) that other forms of filtration such as ozone and uv sterilizers have taken a back seat.

I've stopped vodka dosing due to problems associated with maintaining a ULNS system with amino acids and increased feeding. I do run GFO and Carbon through a BRS Dual reactor but was still very interested in exploring ozone. With these new chemical agents able to strip the water column of nutrients, would ozone be of that much benefit to my system? I have a large skimmer (ETSS 900) on a 150 SPS tank, with crystal clear water but was wondering if there was that extra little "something" ozone might offer. My parameters are as follows:

NO3: 5 (excellent coloration as opposed to when I was at undetectable)
PO4: undetectable (no nuisance algae anywhere)
SG: 1.025
dKH: 10
Ca: 420 - 440
Mg: 1350

Any suggestions?

well why do you want to keep filtering?. is the tank/corals not looking good?. if the corals look good then leave it imo.
