Caryl Posted July 29, 2008 Report Share Posted July 29, 2008 Sounds like cyanobacter. Something is out of balance. Try lifting out as much as possible then do a total tank blackout for at least 3 days. Don't feed the fish during this time either. Then do a good water change and siphon. It would be good if you can find the cause. Can be brought in on plants or in water from another tank. Quote Link to comment Share on other sites More sharing options...
Cheesejawa Posted July 29, 2008 Report Share Posted July 29, 2008 Caryls right blackout will probably kill it although some types of algae seem harder to kill that others. More water changes will help too, no matter what type. Quote Link to comment Share on other sites More sharing options...
whetu Posted July 29, 2008 Report Share Posted July 29, 2008 Yeeahboy didn't you just do a blackout and algae-fix treatment to get rid of green water? Sounds like something has got seriously out of whack in your tank! Can you describe the slime some more (a photo would be even better). - What shade of green is it - dark, light, bright? - What is it growing on - glass, plants, water surface, substrate? - How does it behave - does it peel off in sheets? Does it break up in the current or hold together? Quote Link to comment Share on other sites More sharing options...
yeeahboy Posted July 29, 2008 Author Report Share Posted July 29, 2008 Sounds like cyanobacter. Hi i did a bit of research. Yes i believe it is Cyanobacter. I think it was bought in on new plants. Is there any other method other than black out that may work. As i have a planted tank n dont want to kill plants aswell. Iv'e siphoned most of it off gravel & washed down my drift wood with a hose. but even if there is a tiny bit in tank it mulitplys fast Quote Link to comment Share on other sites More sharing options...
Rockerpeller Posted July 29, 2008 Report Share Posted July 29, 2008 plants should be able to withstand a few days without light. Quote Link to comment Share on other sites More sharing options...
SpidersWeb Posted July 29, 2008 Report Share Posted July 29, 2008 My ex gets big cyano outbreaks whenever she adds plant fertiliser. So if you're doing that, I'd recommend not. Outbreaks are usually the result of something being unnaturally out of balance. e.g. tonnes of one nutrient but none of another. This can be caused by adding tank fertilisers unnesecarily or deposits found in cheaper tropical fish foods (usually not a problem with regular partial water changes but worth mentioning) Plants can surive without light for a few days, cyano can not. Keep it blacked out though, like completely blacked out. Unless your fish are starving they'll make the 3 days without any problems as well. But once its gone, if you haven't corrected the inbalance, it'll be back. Quote Link to comment Share on other sites More sharing options...
Caryl Posted July 30, 2008 Report Share Posted July 30, 2008 Mine came in on plants too so once treated, it never returned. Try the blackout first. If that doesn't work, you may need to treat with Erythromycin (a prescription only drug). I may have some spare if required. Quote Link to comment Share on other sites More sharing options...
yeeahboy Posted July 30, 2008 Author Report Share Posted July 30, 2008 thanks for help. will try a black out. just a bit gutted cos i just did a black out to get rid of green water. when will i get to watch my fish ah!! :lol: Quote Link to comment Share on other sites More sharing options...
DiscusDiva Posted September 30, 2008 Report Share Posted September 30, 2008 what is the correct dose rate/period? Quote Link to comment Share on other sites More sharing options...
Caryl Posted September 30, 2008 Report Share Posted September 30, 2008 This is what I did; Pills are usually 400mg each. It as been suggested 400mg/100L. Someone else said 250mg/100L but I think the 400mg/100L may be better. Dissolve required number of pills in about ½ cup of water. They dissolve very slowly as they have a coating on them. Give them a stir every now and then to speed up the process. Once dissolved add it to your tank, swirling the water around to spread it quickly. The stupid fish will think it is food and try to eat it but don’t worry about that. You should notice the cyano dying off within 24 hours or so. It is important to keep siphoning up the stuff as it dies or it will pollute the tank. After 3 days, dissolve and add another dose of pills (same as first dose), siphoning out the dead cyano remains as required. People worry about it killing the bacteria in the filters but I kept my filters running the whole time and noticed no difference. I was told the bacteria in the filters is the wrong sort and is unaffected by the erythromycin. Something to do with gram -ve and gram +ve bacteria.

DiscusDiva Posted October 1, 2008 Report Share Posted October 1, 2008 great, can you dissolve them in boiling water to speed up the process?? does that have any effect? Quote Link to comment Share on other sites More sharing options...
Caryl Posted October 1, 2008 Report Share Posted October 1, 2008 I wouldn't dissolve them in boiling water. It doesn't take that long to dissolve them and it is fun poking them about Quote Link to comment Share on other sites More sharing options...
