MTAquatics Posted January 25, 2021 Share Posted January 25, 2021 Hi Everyone! Does anyone know if there is a UV sterilizer to treat green water in a 10 gallon tank? The 9w green killing machine says it's 12" long. Is it possible to lay it on its side? Link to comment Share on other sites More sharing options...

Ryan W Posted January 26, 2021 Share Posted January 26, 2021 It will work in any orientation. It’s just a uv-bulb attached to a power head. As long as the pump functions, it doesn’t matter how it’s placed. You can even position the outflow above the waterline if you want. If you get one, don’t be alarmed by the “weak” pump. UV sterilizers need slower water flow to ensure that the UV is actually doing it’s job. If water flows too quickly over the light, it’s essentially useless. Kind of like how if you move your hand quick enough over a flame you won’t get burned but if you go slow you will get burned. In your tank, things need to travel through the UV chamber slow enough to be burned. Quite literally actually. 1 Link to comment Share on other sites More sharing options...

FrozenFins Posted January 26, 2021 Share Posted January 26, 2021 The problem with a uv sterilizer with green water is that the green water will come back if you don't adress the issue. Ask yourself why do I have green water? Is it because of too much light? or too much nutrients because your overfeeding? etc. If its too much nutrients I would add more plants to asborb the nutrients that the algae is consuming. If its too much light, block out all light out for a week and then decrease your lighting schedule. If you still wish to get a UV Sterilizer you have some good suggestions above Here are some video that I found helpful when I dealed with green water: 1 Link to comment Share on other sites More sharing options...
Ben_RF Posted January 26, 2021 Share Posted January 26, 2021 (edited) Edit: This is a uv sterilizer that you can clip on to your hang on back. I use this for my 10g when I need too. The product name is AA Aquarium Clip-on Uv Sterilizer 3W Green Killing Machine however, it appears not to be on Amazon at this time. Edit: I did find it on a popular pet website, so if you search in google for it you should find it fairly easy.

shkote Posted January 27, 2021 Share Posted January 27, 2021 (edited) I used the mini GKM on my 5 gallon portrait at work not that long ago. After an over feeding/way too much light situation over vacation, I came back to a glowing green cloudy tank. The mini 3W green Killing machine was a bit bulky in the 5 gallon, but it was all I had so I stuffed it in there and turned the flow all the way down. It started clearing up within days. I don't know if you have access to the mini version, but I'm sure it's powerful enough for a 10 gallon and would fit nicely. I can't remember exactly how many days I ran it, but it wasn't very long.

Brandy Posted January 27, 2021 Share Posted January 27, 2021 I have a small uv sterilizer from Amazon. (COODIA Internal Green Water Killer Filter Aquarium Tank U-V Light Pump) With no or low substrate I was able to place it vertically in a 10gal, but I suspect you could angle it also. My only concern is that the flow rate was quite high for 10gal It worked well for the algae, but I had to work out a way to diffuse the flow or trash the scape a little. Guppies and shrimp tolerated it, short term. 1 Link to comment Share on other sites More sharing options...

The green water was the result of too much light and not dosing enough fertilizer. I have reduced the light and I'm testing regularly to figure out a proper fertilizer schedule. I ended up purchasing a UV sterilizer to get rid of the green water short term while I figure out the balance of the tank so it doesn't come back. 2 Link to comment Share on other sites More sharing options...

Daniel Posted January 30, 2021 Share Posted January 30, 2021 @Colu thanks for the update. Does the UV run continuously? If it does run continuously, do you think your water would go back to being green if you stopped using it? Link to comment Share on other sites More sharing options...
