I've read forum threads where people have used aluminum oxide phosphate removers (Phosguard) and reported good results. Aluminum oxide absorbs silicates as well as phosphates. I know on RC aluminum is said to be a no no, but as far as I know that is unsubstantiated. In any case I would research it before I used it.
Test first, silicates may not even be your problem.
