Started zeovit on 7th Sept 04 but only started to use the Hanna PO4 meter on 30th Nov 04.
Before that from 7th Sept to 30th Nov using salifert and showing colorless reading.
PO4 Trend (with hanna PO4 meter)
Zeostart1 dosage (have not started using zeostart2 yet). Can see that the zeostart dosage needed is reduced as the nutrients level in the tank drop. Have stopped zeostart1 dosage since 21st June 05 and PO4 is now 0.00 (undetectable with Hanna PO4 meter), can officially say I am in zeovit stage 3 now (all pooled nutrients have be eliminated) and just the basic 3 is sufficient to keep nutrients low.
From what I can see from the last 10 months, zeovit does works, other things aside, it does help keep the water very clear (clearer than using Ozone), reduces and keeps the nutrients level low and brings out the colors of the SPS. Even pastel colored walt smith SPS are possible to be kept now.
Zeostart1 dosage. Dosage needed are reduced as the time goes by.
