internal UV filter recomendation?

so i am having a headache with greenwater algae and don't feel like waiting forever for it to clear. i was looking at submersed uv fitlers but the LFS only had one. wanna see if anyone can recommend something?

i have a 55gal and want to stay away from inline uvs since i don't have anyway to drive it. and don't want to have to buy a pump and a uv light.

The green killing machine will do the job. It's an all in one.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

Petco sells The Green Killing Machine. Even if your local store doesn't have it in stock, I noticed orders arrive quickly to Ohio with standard shipping.

that's the one my LFS has, read a lot of reviews that the replacement bulbs are hard to find and the unit itself gives out after only a few months. (seals go bad) any alternatives out there?

Check out the Aquatop Submersible UV Sterilizer on Petmountain.com. Not knowing anything about UV, that one sounds attractive to me. Free shipping too. Usually takes 5 days from there (San Diego).

seems all the submersible uvs have the same issue with o rings giving out. I found this one Aquarium Ultraviolet Clarifiers & Sterilizers: Aqua Medic Helix Max UV Sterilizers the 5watt is good for up to 75 gallon tanks. I have a maxijet powerhead that can be converted to a utility pump and has like 175 ghp rating. think I could get away with the combo?

No. There are 2 components of UV filtration - exposure time and the bulb wattage. The stronger the bulb, the more (and more quickly) it kills. Exposure time is how long the things spend in front of the bulb - the longer the better. The best UV filtration is a stronger bulb with a lower GPH. The green machine is like 50 gph, for reference. The worst UV filtration is a weak bulb and a high turnover rate.

makese sense there J, I did find a 9 watt unit rating for 200 GPH max flow has a internal spiral flow pattern for extended exposure. the 9 watt unit is a little bigger and only like 9$ more.

is it turbotwist? 200 gph is way to much. If the pump is not part of the unit, then you can get something considerably less, too get the maximum benefit from it's use.
