Phosphate question

[TheGeneral75]

Other than water changes, what's a good way to reduce phosphates? Right now mine is about 0.25 ppm

A reactor (take a look at www.bulkreefsupply.com and Granular Ferric Oxide (GFO) also from BRS

How old is the tank?

You know the source?

You can also reduce bio load or throw in macro algae if you want to attempt it the natural way.

Also if you have measurable nitrates carbon dosing can be extremely good at reducing P.

Carbon dosing might well work for you. IMO, it happens to be the cheapest way to reduce PO4/NO3.

I have stopped GFO/GAC reactors as well as ATS and am relying on carbon doing and very efficient skimmers. After three weeks PO4 and NO3 are reading 0 with Hach PO4 kit and 0-1 ppm with NYOS NO3 kit. As a result I am increasing feeding gradually in both my tanks. The only downside so far is that I have to clean skimmers every other week because they accumulate so much bacteria snot).

It's only been 3 weeks, of course, so for all I know I may be heading for hell in a handbasket but so far so good.

Good Luck,

Mike
