ThunderKat,

If you are in fact using tap water, get an RO/DI unit. I recently switched over and it has made a world of difference to my tank. Lago Vista use to use just chlorine in the tap water and that was fine until they switched to chloramine. Chlorine can be easily removed from the water via agitation. Chloramine cannot be removed at all, only changed to another compound that is not harmful to your fish. However, the converted compounds apparently make great fertilizer for the algae. After a couple of mouths my algae went crazy from the abundance of nutrients in the tank. After switching over to RO/DI water, I can see a marked descrease in algae production but it is taking time to reverse the effects of using tap water.

HTH
Wow, I never knew about that. Maybe that is why my tank in Hawaii was sucessful and my aquarium here in San Antonio is a death trap to all but my current inhabitants. I live in an apartment so I can't install an RO unit but I can still buy some at the store. I have read all the posts and in the process or have already implemented them.
