Brown algae

[frostiex]

So with out changing the water source there is no way those Diatoms will go away? Is there anything you can put in the water to get rid of the silicates?

I saw on ebay someone is selling a aqua safe RO filter or something...are they any good? the price isn't too bad.
Are those only good for aquariums? or can it be used for drinking as well?


thanks for the help
