Bertoni, i am using hanna's phospate meter for testing, and PH Meter calibrated regularly for PH measurements. on Salifert the Phospates are less than 0.03!!!.
Will a large water change solve the Phospate problem?
started to up the PH around 8.4 to 8.5, but i need to add about 20grams of Calcium Hydroxide every 3 hours to maintain at that level!!! is that ok? or will that take my other parameters such as CA (@420) and Alk (@7) (Both measured by Salifert) out?
There are many variable results on Hydrogen Peroxide, i also have purchased it, but not sure whether to do or not.. as many people say they didnt get results!!! - what to do?
I was thinking,
1. will try to maintain the Ph around that level, and see what the results are... Actinics are ON.. will turn on my Lights (Whites) slowly... using LEDs so easy to do.
2. Will do a 50% W/c with Red Sea Coral Pro Salt, to see if that will reduce phospates. May be my Natural Sea Water is the problem... when measured it has 0.15 ppm phspates!!!
3. Will change the GFO again today...
