Is this UV Sterilizer everything I need?

What is the media in the C220?

Reason I'm asking is I'm running a c-160 on a 29 so a step down and I had a cloudy water issue until I made some mods.

I took all the bio balls and put them in one tray and the loaded the empty tray with pot scrubbers and filled the gaps with filter floss this increased the bio load the filter could handle by a long shot and with in a week my cloudy water cleared up.

I got all the new stock stuff the filter came with, I just got the filter a week ago. There is 4 compartments that are completely full.
 
Well if it has only been a wek give it another sometimes it takes a week or more to cycle the filter.
 
I had this problem bigtime in my 200g pond. Uv did nothing but waste my money. On a tip from someone here I removed some bioballs from my filter and stuffed everything down tight with thick layer of cotton stuffing material. Problem went away in 2 days and has never returned.

Jag - just to let you know 12+ hours and the water is still the same. I get a bacterial bloom everytime I dose with calcium and with my normal filtration it clears in 24 to 36 hours. So I can say at this point the UV is not making a difference I will let you know what it looks like in the morning.

If you're dosing calcium and seeing blooms after that, it might actually be precipitation.

My Calcium is in a jello based food that I feed every 3 days. So in a since it is coming from the added vegie material in the jello not really the calcium.:)

ah in your case, then its just pieces of food in the water

Nope not pieces of food...

This is a 62 gallon with close to 100 mollies swiming around at this time, so when they feed on the food they spread it all around. About 24 hours later I get a bacterial bloom as the waste and leftover food is consumed by the 1000+ snails finishing off the remaing and then adding their waste to the system. So I do not see the cloudiness until much later so that rules out the floating food theory. I have had this off and on in this tank as the # of mollies wanes or grows. More Mollies more cloudiness I see, basically a mini cycle every three days or so due to a nutrient overload. I have had this problem many times over the years and get basically the same occurance when I feed my Jello based foods due to the high content of plant material in the food itself, but only in this tank since it is overstocked. So if it was suspended food material I would see the same thing in my other tanks where they get the same food. Since I have gone to the large canister filter the cloudiness goes away in about 24 hours. When I was running the smaller HOBs on the back it took 2 to 3 days to go away.

I used to panic and do water changes, but after so many times and testing when the cloudiness appears and the stats are fine I have gone back to my regular water change schedule.

That is what I mean by increasing the bio load ability of the filter. Using filter floss instead of the pads the filter came with increase the surface area for bacteria to grow and will still filter the particles out just as well. That is also why I add the pot scrubbers since they give a huge surface area to size. Only down side is you might have to clean out the filter a little more often but at $4 bucks a huge bag at the LFS that can due 5 changes on one filter is a lot cheaper than $3 bucks a pad that I may get an extra week of filter time out of.

I still say give your filter another week or so and see if the cloudiness goes away before dropping the cash on a UV. I have UV's on 2 of my tanks built into the filters and except for the test I did they have only been on once before.
 
I agree that it won't help the cloudy water. If it was green then it would help. With that sterilizer like someone said you need some type of pump, like a power head or canister filter to drive it. If you want one that you don't need a pump then you can go with one that is made by JBJ it is called a Submariner UV Sterilizer/Clarifier. This is the link for it: http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+4393+19643&pcatid=19643 It is more expensive then the one that you were looking at but it might be better for what you need.
