I'm thinking of getting a UV sterilizer, maybe a Turbotwist 9watts for my 75g. What do people think of them in general and what are some of the best brands?
Is it for algae control or parisite control?
If for parisites you might think about the turbo twist 18w with about 200 gph flow.
If you just wanna kill free floating algae, the 9w will work.
I would go with the 18w TT
or just get crazy and get the 40 watt for ponds. LOL
