Questions about UV Sterilizers

[ragc]

On another post, someone said no.

It cleared it up for me and also in my daughter's coldwater tank. I'm not about to offer a guarantee, as I have nothing to gain by it, but I know it works. It can take several days for all the water to circulate through the device, depending on tank size, unit size, and flow rate of the powerhead or power filter running it. If you don't want the expense just cut feeding and remove all decomposing matter and the overpopulation of bacteria causing the bloom will eventually die off, giving you clear water again. The UV Sterilizer just kills it quicker, bit it's the same thing.

sorry for bumping this old thread, but....

my tank is outside, right by the entrance to our backyard. we have a canopy so there is no direct sunlight. I'm in the southwest where it has been extremely hot and humid these past few weeks.

my question is I'm thinking a uv-sterilizer is probably my best bet. A blackout might just be a band-aid for the time being. My freshwater tank has 0 ammonia/nitrites, nitrates 10ppm, 7.2pH with one marineland bio-wheel 350 power filter. Would just buying one of those uv-sterilizers (i.e., coralife turbo twist) be sufficient? What's this I hear about a powerhead? IN other words, would the uv-sterilizer be connected to the power filter? Would there be any parts needed or would the power filter and uv-sterilizer be enough?

Also, since my power filter filters 350 gph, would I need a uv-sterilizer to be filtering equivalent to 350?

lots of questions, but it's been nearly two weeks of partial water changes and this green cloud of doom is still very prevalent in my tank. Thanks in advance for any help/info.
