megs27 Posted August 29, 2009 Report Share Posted August 29, 2009 I have Daltons aquatic mix on the bottom and washed sand on the top for a substrate and doing 100lt water changes every two to three days in a 300lt tank also using TLC for freshwater aquariums and I can't seem to get rid of green water. Would it be something to do with the substrate or maybe a plant would be the cause. Has anyone else had this problem and how do you fix it. Thanks Quote Link to comment Share on other sites More sharing options...
SamH Posted August 29, 2009 Report Share Posted August 29, 2009 Try a week long blackout. Cover up the whole tank and turn off all lights. Feed fish once a day if needed and check if water is clear again. Once clear you can go back to normal. I don't think the substrate is doing it. How new is the tank? Plants compete with algae so those will reduce it in the future. Quote Link to comment Share on other sites More sharing options...
Bilbo Posted August 29, 2009 Report Share Posted August 29, 2009 I found a huge rise in brown algae with daltons at first but it settled after a while. I wish I could make green water, even when I try to I cant. Quote Link to comment Share on other sites More sharing options...
megs27 Posted August 29, 2009 Author Report Share Posted August 29, 2009 You want me to send you some green water :lol: Would a week long black out be ok for my fish (Discus and Rams) the tank has roughly been set up for 6 months. Quote Link to comment Share on other sites More sharing options...
N1CK Posted August 29, 2009 Report Share Posted August 29, 2009 can't seem to get rid of green water. Try some daphina Is there some way the nutrients could be seeping into the water?? Quote Link to comment Share on other sites More sharing options...

N1CK Posted August 29, 2009 Report Share Posted August 29, 2009 It's a small crustacean that feeds on algae in the wild, and fish seem to enjoy eating it (also called water fleas for their jerky movements) Thats what they look like except waaay smaller Quote Link to comment Share on other sites More sharing options...
supasi Posted August 30, 2009 Report Share Posted August 30, 2009 Firstly, lets look at possible causes. I use exclusivly Daltons and do not have green water issues, so maybe there are other factors. You have not mentioned you lighting regime or intensity. Have you tested the water for Phosphates?? How much are you feeding? Where do you source your water? There are many factors to keep in mind with algae, and unless you find the cause, you will more than likely be battling it again in the future. WHile the Daphnia idea does work, It certainly will ot in a tank that houses fish. The fish will love you for it, but the Daphnia will not last more than ten minutes. Here is a great link to an article about algae. Its causes and how to control it. http://fishkeepers.co.nz/forums/viewtopic.php?f=50&t=287 HTH Quote Link to comment Share on other sites More sharing options...
