really that's seems unusual. Are you sure you eliminated the possibility of the product simply no longer being able to adsorb phosphate and a new source of phosphate adding phosphate to the water (food, etc.)?
see here:
Over treating is not recommended. PhosGuard™ is not an exchange resin, it does not release anything into the water. It does not leach phosphate or silicate back into the water and may be removed, dried, and returned to service until exhausted.

I've done both the ChemiPure Elite and the regular ChemiPure. To be honest it still looks like the Seachem products outperform the other and because I tend to use up the media at different rates I feel it's a little more economical for me to use a separate phosphate remover. If it's combined and one of the two is used up I'd have to replace them both.
I have a huge tank and feed a lot so I have to look for stuff that is both effective and economical. can't beat the Purigen in that regard.
