Truthfully I find most, if not all, of Marc Weiss stuff snake oil. What issues are you having, if I may ask? Is it just phosphate.. or is it silicates too? (And are you sure it's silicates?)

i have diatoms that keep coming back in the morning they seem low but as the day goes on they get worse.

It's most likely Lanthanum chloride just like most other (if not all) liquid phosphate removers. Personally, Marc Weiss and his ex-wife is about the last people I'd ever want to give me money to...

How long has your tank been set up?

Try using some phosban firs before going after silicates. Either phosban, BRS, etc should be fine, but Weiss' stuff.. I would avoid all together.

i have been using phosban but it does not seem to help,my tank is about five years old but i changed the substrate from crushed coral to live sand and this is when the problem started.could it be the live sand.

please help mike:sad:

Try some Phos-zorb that does both as well and I have used it with good results.
