What does 0 Nitrates Imply?
I have a spec V. I've modified it to hold about 750ml of fluval biomax and 100ml purigen. The substrate is only about 1cm thick of pool filter sand and it is constantly turned over by a hoard of MTS (The sand is probably more snail than sand by now).
The tank has 1 betta, 4 ottos (3+ years old now!) and 7 ~1-1.5" microsynodontis.
The tank is planted with floating wisteria fern and anubias.
After a while of only dosing PK and mircos I found out I had been running on 0 nitrates.
I think this means that the plants are outstripping the supply of nitrates.
What I'm wondering is if it's safe to correlate this with appropriate bioload in the tank? If I were overstocked would I observe an excess of nitrates? This of course doesn't mean I plan on adding any more fish.
I'm just worrying about the health of the fish. The catfish themselves are VERY sedentary and cryptic and I actually see them with eggs all the time and I'm working on trying to get them to spawn.
