jgreenslade89 Posted June 23, 2011 Report Share Posted June 23, 2011 Hi There, Have green water, bought a UV Filter, will this fix the issue? If so for a 105Lt tank how long will it take? Anything I can do to help speed up the process, tank not in direct sunlight. Quote Link to comment Share on other sites More sharing options...
Adrienne Posted June 23, 2011 Report Share Posted June 23, 2011 Yes it will fix the issue but will not fix the problem causing it. If you black your tank out so there is no light for a few days this should also fix it. For both solutions I would say around 3 days or if very thick green maybe up to a week.

jgreenslade89 Posted June 23, 2011 Author Report Share Posted June 23, 2011 oh so should I get like a sheet or a cover and place it over the tank ( so no light can come in) for the weekend? Quote Link to comment Share on other sites More sharing options...
jim r Posted June 23, 2011 Report Share Posted June 23, 2011 Green water will not harm your fish and is beneficial to fry so no need to black out your tank if you already have the UV. Quote Link to comment Share on other sites More sharing options...
Insect Direct Posted June 23, 2011 Report Share Posted June 23, 2011 addressing the possible cause: could cut back lighting hours. less food for fish and or plant ferts if using them. more water changes. bigger filter maybe. sometimes just a sign of tank not being cycled fully / newly set up / not enough good bacteria (cleaning filter too often) etc green water should just go away once you find the balance.

GZ_Loach Posted June 23, 2011 Report Share Posted June 23, 2011 partial water changes also need to be carried out atleast every 2 weeks Quote Link to comment Share on other sites More sharing options...
David R Posted June 23, 2011 Report Share Posted June 23, 2011 Shouldn't you have been asking that question BEFORE buying the UV filter? Quote Link to comment Share on other sites More sharing options...
fishplants Posted June 23, 2011 Report Share Posted June 23, 2011 Uv filter will fix the symptoms, if a relatively new tank then it will likely not come back as the tank matures and finds a balance. I wouldn't turn off the lights and black out the tank (unless you don't have plants?). Very frequent water changes will also reduce the quantity of algae while you have the UV running.

Supaclear Posted June 24, 2011 Report Share Posted June 24, 2011 i run UV 24/7 and i know plenty of reasons why i shouldnt have to, yet i do....when i was checking it all out i was trying to fix green water myself. turned out it was a bacterial bloom that looked supergreen because of my heavily planted tank diffusing green light. i checked the water by straining it through a tissue to look for algae but it was clear. UV took about 10 days to sort it, it may have sorted itself in that time but i wanted to try it out. main advantage i can see with UV is that its another line of defense to a few problems but its not the full answer. i have read that UV can benefit redox levels in fresh water tanks and this helps fishes. I dont know but it all sounded very plausible at the time. Quote Link to comment Share on other sites More sharing options...
