Hanna Checker Nitrate

[hyeclass]

I just did fished doing a water change 35 gal on 140 gal tank hanna checker was flashing 5.0 after the water change now the input on the checker is reading 4.89

Anyone using the checker?

When it blinks 5.0 that means the reading is too high.

Do you keep your tank lower and now have a higher reading with this tester?

Sump

Nitrates should be around 10X phos so if your phos is at .2 and Nitrate around 4 then you aren't too far off. Perhaps time to put new phosgaurd in?

Is this a fish only tank?

That is a lot of larger tangs for a 140g. They produce a lot of waste. Maybe looking into a bigger skimmer or nopox dosing to keep the numbers lower...

I have corals also in the tank I am using q3 by aquamaxx it's a great skimmer wasn't sure where to put the prosgaurd

Ya that's a tough one as they drop easily into a nyos reactor but without room for something like that the only place is in the filter socks.
