Pet Forum / Aquaria / Marine Reef / September 2003UV Sterilizer
I recently added a CoraLive turbotwist 9watt to my sump to fight the pest algae in my tank (cyno mostly) Anyone have any experiance with these or similar units? How long before they make a difference? I am running it with an 802 powerhead 24 hours a day. Its in my 20 gal sump (66gal tank) i dont know the specifics for you uv unit but an 802 pushes close to 400 gph, thats way to much flow IMO for a 9w unit. kc > I recently added a CoraLive turbotwist 9watt to my sump to fight the > pest algae in my tank (cyno mostly) Anyone have any experiance with > these or similar units?

UV sterilizers work best when the water flows through them at a very slow rate. > I have the 802 cranked all the way down to the lowest flow setting so > I dont think its too high..

Its in my 20 gal sump > (66gal tank) Not sure about cyano but I have had good luck with UV sterilizers helping with algae- after I cleaned my glass and put the algae back in the water, I could tell if my UV sterilizer was running as it would affect how long it took for the grass to get scummy again. That's something of a stop-gap measure though since you still leave all those nutrients in the system and they simply get consumed by something else at some point. I don't run that particular tank anymore but it was a 220G tank with very heavy lighting which made the algae somewhat difficult to control at times. Marc  Signaturehttp://www.four-hands.com/marcs_stuff.htm Well I read up on cyno... and tested my tank. Phosphates are 0, Nitrates are 0 and NO2 and NO3 are zip. The only thing I have changed in the tank are the lights... I have to VHO URI Super Actinics and two 6500K NO Phillips on an Icecap 660. The 6500K are new to me.. I used to run the URI VHO actinic whites. I tried the 6500Ks as they are quite cheap.. but I am going back to the URIs. I never had this problem in my old tank. I have a 402 and a 202 power head running as well as the return from the sump. There appears to be good flow.... <marc@four-hands.com> wrote: >> I recently added a CoraLive turbotwist 9watt to my sump to fight the >> pest algae in my tank (cyno mostly) Anyone have any experiance with [quoted text clipped - 13 lines] > > Marc > ...................... > Nitrates are 0 and NO2 and NO3 are zip. ............. Nitrates are NO3. kc |
