I've had ZERO nutrient levels for weeks now despite overfeeding and dosing TM Plus-NP, (doubling the dose didn't help). Before I start trying other chemical products I'm curious about increasing my phyto dosing. The tank is fish only at this point and phyto is feeding pods. The only negative consequence I've found of overfeeding phyto is rising nutrients. That being the case why not try using something natural which will help boost my pod population? Currently I'm adding 30mls Ocean Magic daily to a 150 gallon tank which has no coral as yet.
