I have a 125g FOWLR setup with a fairly heavy bioload/feeding schedule and decided to start dosing NOPOX. I am currently on week 4.
Starting param:
Temp 78
Salinity 34-35ppt
pH 8.2
NH3 0
NO2 0
NO3 20
PO4 0.03
Based on NO3, instructional dosing is to start at 3ml/25g; however, given all the threads of side effects that I went through on this site - that can an aggressive dose. So I started at a 25% dose and escalated each week by 25%. DT displaced water volume and sump estimated around 130g so I am dosing for 125g. I am dosing on a doser.
Week 1 - 3.75ml total, no issues
Week 2 - 7.5ml, skimmer starts going a bit crazy toward the end of the week, no change in water params.
Week 3 - 11.25ml, skimmer is going absolutely *BSC and overflowing after each dose within hours - uggggh. Octo Essence 130 - raised the skimmer to 7" from 7.5" and run it wide open now - skims wet then settles to dry and have to close it down. And an expected thin glaze on interior walls that wipes right off. no change in water params.
Week 4 - yesterday was my first full 3ml dose, so 15ml total. 4 hours later, I have the white film on the glass (no biggie), but notice some very small amounts of white stringy slime coming from the power heads and a thick clear snot ~1/8" thick clogging 3 mesh filter socks which had just been changed the day before, its also coating my return pump and the entire contents of the skimmer.
I read up and there are a lot of "nopox slime" threads with all kinds of courses of action.
The water is not cloudy but there is intermittent white sediment in the water column from the power heads and return, there is no white or slime accumulation in low flow areas or on the coral insert, pH is stable, po4 0.04 (GFO off at beginning of treatment), NO3 15.
I did not over-react, just dismantled and cleaned the return pump, skimmer and changed filter socks.
I cut the dose back in ~1/2 and dosed 8ml today with no issues. Fish look fine.
My question is.... is this expected and has to be managed this way every day with dosing full strength or is this a sign of overdose?
Thanks!
