zeebee Posted June 10, 2012 Report Share Posted June 10, 2012 Hi guys, I am going to get some furan 2 today to try kill the blue green algae (cyanobacteria). Wanting to know if this would also kill brown diatoms? Quote Link to comment Share on other sites More sharing options...
blueether Posted June 10, 2012 Report Share Posted June 10, 2012 I don't know if furan 2 will work. I believe that erythromycin is what is normally used for cyano Quote Link to comment Share on other sites More sharing options...
zeebee Posted June 10, 2012 Author Report Share Posted June 10, 2012 Where do I get that from? Is it cheaper than furan? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 10, 2012 Report Share Posted June 10, 2012 Legally it is dearer as you have to go to the vet and get a script. Furan works. Quote Link to comment Share on other sites More sharing options...
Joe Posted June 10, 2012 Report Share Posted June 10, 2012 Just give the tank a blackout for three days. That will kill the cyano. Try and get rid of as much as possible first so there is less polution. I've done this before when I had cyano and it works wonders, not need for fancy chemicals and you can spend your money on more plants or something else :thup: Quote Link to comment Share on other sites More sharing options...

zeebee Posted June 10, 2012 Author Report Share Posted June 10, 2012 I would do a black out, and have done in the past, however I have plants now, and scared they will die along with the cyano... Quote Link to comment Share on other sites More sharing options...
blueether Posted June 10, 2012 Report Share Posted June 10, 2012 plants should be fine Quote Link to comment Share on other sites More sharing options...
zeebee Posted June 10, 2012 Author Report Share Posted June 10, 2012 Hmmm i suppose they would recover..... The BGA only came when i got a new bulb for the light hood Quote Link to comment Share on other sites More sharing options...
Joe Posted June 10, 2012 Report Share Posted June 10, 2012 I had plants (not a lot though) when I had the cyano and they survived the blackout with no problems :thup: I've found though that if the tank is chocca full with plants you shouldn't have any problems with algae at all.

Caper Posted June 10, 2012 Report Share Posted June 10, 2012 Does the 3 day black out work for all types of algae??? Just wondering :dunno: Thanks, Caper Quote Link to comment Share on other sites More sharing options...
Caryl Posted June 11, 2012 Report Share Posted June 11, 2012 No but it can be extremely effective for cyano - depending on the cause. Cyano is not algae. Quote Link to comment Share on other sites More sharing options...
