My tank has PO4 < 0,01 mg/l. and NO3 0,5 mg/l.
I started 11 days ago with NP Plus to increase the phospate.
I begun with 25% of full dose.
This morning I did a PO4 test (Tropic) but always 0,01. Tomorrow I will increase the dosage to 50%.
The skimmer is running very different, more dark and bad smell.
At the moment I have not seen any big differences with corals, maybe they are a little bit more swollens.
To be honest, I never had big troubles with them but I don't want to mantein values too low, it is no good for animals.
