How many times should your filter your tank over

[Triton]

I have a 200 gal (7'x2'x2') with a wet/dry sump, 36W UV sterilizer and 7 goldfish (about 6-7 inches). I have a Mag12 (1200 gph) set up, where about 300 gph goes thru the UV and 900 gph goes thru the filter system. So its about 6x turnover, but a portion is recycled back to the sump via UV sterilizer. I also do a 20% water change weekly to keep algae from setting in and to keep the chemistry and tank temp from changing too much. I would do a bigger water change, but I'm a little lazy. I almost forgot, about 50 nerite snails doing a great job eating any algae on my plants (java ferns, anubias, etc).

I found that there are a lot of fuzzy variables in keeping a tank clean and fish happy. After some trial and error and more errors, I finally discovered a mix that works. With everybody doing their part in keeping the tank clean, I get to spend more time enjoying other things. (that is, if I did have other things to enjoy )

I already sort of asked this question. I feel the consensus is as on page one. That normal readings indicate your okay, however more turn over just increases current and saturation of O2 which of course is good. I am turning over 10-11 times an hour which I am fine with. I don't see the point in getting manic over trying to get 15, I doubt it would make a difference to anything useful...

Actually it just increases the current. The saturation index is temperature and pressure dependent, but has nothing to do with the amount of flow.

Actually yeh, what am I on about! Thanks for the correction.
