Darn Cyano Bacteria. I recently (Friday) waged an all out war on my continuing problem. Here is what I did.
What I had:
20 gallon all-glass.
Tom products canister filter (Don't bye this item, it sucks)
Hydor 100w (I think) heater
Energy Savers Unl. 24" Aqualight w/1-10,000K & 1-Actinic T-5 Bulbs...
