Anybody local used it? Lots of info/debate online. The ferrous metals and some other stuff on the MSDS are a little scary but there are plenty of guys out there using it without (verifiable) ill effects and it looks great. The price tag looks especially good - 50lbs = 8 bucks).
Probably gonna do it unless somebody tells me they lost all their fish etc./etc. Sponge covers on filter intakes were already part of the plan.
UPDATE: Don't do it unless you love the look of Diatoms in your tank (high silica content). It's not harmful, just ugly.
