phosphate zero, possible?

[speakerphone]

Is it possible?

Athoug I use Fr, although I use rowa phos, although I change water, althoug i use skimmer its still 0.5 no matter how.

when i change water, and measure the next hour, the reading will be zero or o.1 but after 1 or 2 days it shoot up again to 0.5 or sometime even 1. THis has been happening for the last 1 month.

Bro.. how old is your Rowaphos? I heard from a bro that there is a batch issue with Rowaphos... I am not trying to speculate... I'm sure there are some bros here using/used that particular batch of Rowaphos.

I have been using Aqua Medic Antiphos in a Aqua Medic Phosphatfilter for more than a month now...lots of algae... last week, I added a bottle of Aquapharm Sorb-4 and the algae problem is not as bad as before... this is a new product, so have yet to be tested in the long term... but I recommend you to give it a try... it's a lot cheaper than Rowaphos. Bought mine from AM.
