Ultra power phos review

[Aqua-Digital]

You can use the full dose of power phos until you reach zero

BUT and this is a big fat but.

You must test by doing a heat test otherwise your results mean, well not a lot really.

Heat a sample of water to 80 degress C (celcius)
allow to cool for 3-5 minutes
test in the normal manner

By doing this you are releasing bound PO4 molecules back into the water for the test solution to absorb.

Once you have zero under heat test conditions you can reduce the amount of phos being used and then look at other regimes such as LNS ultra Lith system.

For the review do not add any bio please as this will give false results.
