Can never get my water clear

It seems as if my 10G's water is always cloudy or has green water issues. As of now, it's green water. I've tried water changes and black outs. I don't really wanna spend $40 on a UV sterilizer. Is there anyother way besides the UV? Thanks.

UVS & a diatom filter are the only 100% effective ways IME.

Have you tried running Purigen to clear up some of your other water cloudiness issues? I use a diatom filter to polish up the water after any big re-scapes and it works quite well. Also helps prevent any GW outbreaks when you disturb a large amount of your substrate.

I don't know what Purigen is so no. Would Purigen get some of the green water out or no?

Purigen will help clear up some of the "stuff" in the water...but unfortunately, it won't cure GW.

You can try a blackout, some willow branches, etc...they work, but not all the time for me. I've killed a lot of my plants with a blackout, so I'm never going to do it again.

You can sometimes find a cheap Magnum 250 HOT filter on the SnS or eBay...and you can use diatom powder with those.

Just searched for a UV and I saw PetSmarts. If that's the only way I can clear up my aquarium water, then I'll just probably get the UV. For now, what's the best way to get clear water while waiting for some cash on the UV sterilizer?

If you can get your hands on some daphne you could try that. Pretty cheap and tasty for your fish.

I had green water that was so bad you couldnt see your fingers in the tank if they were right next to the glass. I bought the petsmart 9 watt one and in less then 3 days my tank is almost crystal clear. On the second day after about 30 hours of running it in a 55 gallon I changed 50% of my tank water and it worked alot better doing it that way.

Some may tell you dont change water but I didnt want the dead stuff staying in the tank and causing no spikes. I have to say for $45 for the uv to get to my door that thing works amazing. I am not going to let it run all the time once the tank clears I am going to put it on a timer for maybe one or two times a week at night when the lights are out. Pick one up when you can I bet you will wish you did it sooner like I did.

Once the GW clears, I wouldn't run it at all unless you have a reason to.

I was just going to run it maybe once or twice a week as a preventive just incase. I figured maybe like on a saturday night when the ferts will be removed on sunday morning completely anyway via water change.

I know people say they kill ferts but dont think it would hurt on a saturday night till the lights come back on sunday when my water change is done.

I have a koi pond and run a uv all year long and never seen it hurt the plants there one bit so im not sure it kills to much of the ferts.

UV doesn't kill ferts. The only harmful effect I've seen is that it may cause precipitation of chelated iron if you're dosing that. Otherwise, the UV radiation has no appreciable effect on any of the NPKs you dose.

yeah I dose it but there really would be much left at the point it was turned on. I am going to try it on saturday nights since sundays are my water change days anyway. I just figure incase there is anything in the water that may cause a bloom or any parasites floating it may help some. It will only be on about 12 hours a week just as to try and prevent anything and then they could be removed sunday morning with the water change.

Chrisinator, have you tried to determine the source of your cloudy water, be it green water or a bacterial bloom or what-have-you?

Have you tried, for example, to up CO2, lessen fert dosings and fish feedings, or cut back on light wattage and/or duration?

When I get green water, I usually stop dosing ferts as I up the CO2 and then turn down the lights. I then slowly start to increase light wattage until I find that fine balance where plants photosynthesize enthusiastically without algae getting out of hand.

Black outs won't kill Green Water the best way is like everyone said,
lower the light input a few hours a day and run a UV filter.
