What does a phosphate remover actually do?
 

I have a 20 gallon tank with 55w of CF light that's been running for at
least two years. No matter what I did, I couldn't get the phosphates in the
water down. It was coming from my tap water, which was two high to read
with the test kit that I had at the time (it was at least twice as blue as
the highest amount on the test kit, 3 or 5 ppm.IIRC.)

Anyway, I finally got tired of all the algae, and put in some Hagen Phos-X.
The algae cleared up almost immediately, and has stayed away for two months.
I took the Phos-X out, and am going to wait and see what happens.

Now my question: Does the Phos-X remove the phosphates by absorbing it or
by combining it with something else? I guess what I also really want to
know is that if it is combining it with something else, do I have to worry
about that compound breaking down and releasing the phosphates again?

Thanks,
Bruce.

The process is aDsorption. There are chemical binding sites in the
media that attract and grab the phosphate. The media might be able to
release the phosphate again, given the correct conditions. I'm not
familiar with the specific product you used, but I would follow the
replacement and/or recharge instructions carefully.

Cheers,

Andrew

OK -- Thanks Andrew.

I think that answers my question. I was worried that whatever compound the
Phos-X was forming was actually floating around in my water, and not bound
to the media.
