For some reason,
I was dosing Seachem Prime daily
(I thought one of the stickies said to dose this daily until my water is cycled, actually this was a sticky from the betta fish forum)
Also, I have dosed Seachem Flourish Comprehensive once a week (2x total for two weeks).
Are my nitrates too high, should I do a 30% water change?
(On for 10-12 hours a day).
I am using media from a canister filter that has been used in a saltwater nano tank
Seachem Prime daily may alter your water testing.
3 weeks of Prime, 1 cap full a day is 105ml
After using Prime for tank size NH3 usually reads .25 for about 24 hours.
Prime also alters NO2 & NO3 tests, they may not be accurate.
I don't know how long Prime remains before dissipating.
Flourish Comp & Trace and both micronutrients almost same product.
Nitrates are not too high.
I would change water to alleviate the Prime IMO 50%
Maybe then a test is more accurate.
10-12 hours is a rather long photoperiod, 7-8 maybe?
Media from salt water setup should be no issue if rinsed well in warm water.
Thinking about this your tank may not be cycled well.
Prime rendering NH3 less harmful could have prevented adequate bacteria growth.
