Filter Sterilizer price b/w $60 to $200 depend on the brand. Phos-Zorb Filter Media will cost $30 per bag need replace every 2-3 months. from my knowledges UV
Filter Sterilizer will kills some of both good and bad bacteria.
please can I have some recommendation.
sterilizers are almost useless to the average home aquarist.
The only thing they will help with is bacterial blooms or free floating algae blooms.
Studies have shown them to be very ineffectual in parasite control/treatment, they are very inefficient in usually not being able to process the entire water volume or not doing so at the proper speeds for sterilization.
Bottom line, most UV
sterilizers are junk and a complete waste of your money.
The only practical use for them is in multi-tank systems where the water is shared amongst all the tanks, then you actually need a rather impressive array to achieve good sterilization.
I frequent has about 60 24" UV
lamps in-line on their setup.
There are two things that contribute to cloudy water; particulate matter and dissolved organics.
Free floating bacteria are considered particulate, and even if the sterilizer kills the bacteria, you still need good mechanical filtration to actually remove it from the water column. Same with free-floating algae.
So just utilize a good mechanical filter with something that can filter particles down to about 100 microns (filter floss can do this and there are many filter fabrics available),
and particulate matter will be taken care of. Note it usually takes a few days/week before most types of mechanical filters begin to get the really fine stuff, so be patient.
For dissolved organics that can tint/cloud the water I strongly recommend Seachem's Purigen. I like it better than carbon because it induces much less changes to the water chemistry such as ph than activated carbon does and it makes the water amazingly crystal clear. Add to that the fact that it lasts 3-4 times longer and can easily be regenerated up to six times, it is also more cost effective.
As far as the Phos-Zorb goes, you can control phosphates in a freshwater tank in much better ways than using things like that.
seriously, don't waste your money on a UV
