Dave+Amy Posted October 14, 2008 Report Share Posted October 14, 2008 I have these patches throughout the gravel in my tank and some of it's even established on my plants, what is it and what can I add to get rid of it? It's the dark green patch by the loach that's digging, up close it has a blue tint to it Quote Link to comment Share on other sites More sharing options...
Slightly Blue Dalmation Posted October 14, 2008 Report Share Posted October 14, 2008 firstly how big is the tank? Quote Link to comment Share on other sites More sharing options...
Navarre Posted October 14, 2008 Report Share Posted October 14, 2008 Add water flow. add O2 maybe see how that goes? Maybe gravel vax? HTH Navarre Quote Link to comment Share on other sites More sharing options...
Slightly Blue Dalmation Posted October 14, 2008 Report Share Posted October 14, 2008 if it small tank for blue/green siphon as much as can then put in complete blackout for a few days. big tank again siphon as much as can then if comes back eurythromycin Quote Link to comment Share on other sites More sharing options...
Dave+Amy Posted October 14, 2008 Author Report Share Posted October 14, 2008 tank is a 6foot tank, these patches have only started coming up - I've tried gravel vac a few times but they still don't come off. Does anyone know of a chemical I could add without harming the fish? Quote Link to comment Share on other sites More sharing options...
Slightly Blue Dalmation Posted October 14, 2008 Report Share Posted October 14, 2008 eurtythromycin, its an antibiotic as it is technically cyano bacteria. try a vets maybe? Quote Link to comment Share on other sites More sharing options...
Dave+Amy Posted October 14, 2008 Author Report Share Posted October 14, 2008 another thing to add to my list of items to get from the vets... going to be an expensive vet visit lol Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 14, 2008 Report Share Posted October 14, 2008 Adding nitrate to put it up to about 20ppm will sometimes help as will hydrogen peroxide sometimes. Quote Link to comment Share on other sites More sharing options...
Slightly Blue Dalmation Posted October 14, 2008 Report Share Posted October 14, 2008 you would have to be real careful with those would you alan? slightly more precise than guesstimation? Quote Link to comment Share on other sites More sharing options...
Dave+Amy Posted October 14, 2008 Author Report Share Posted October 14, 2008 wouldn't hydrogen peroxide harm fish? or are we talking about minisicule amounts? I thought nitrate was hamrful towards fish (or is it nitrites?).. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 14, 2008 Report Share Posted October 14, 2008 Blue green algae usually turns up when the nitrate / phospate ratio gets out of whack. Too much phosphate can be caused by using the wrong foods and can be reduced with water changes and the ratio improved by adding Pot. nitrate (available from hydroponics places. If you get rid of it and the ratios are still out of whack it will come back. Sorry, I have put you wrong with the H2O2---it can be used to get rid of black beard algae. Furan2 can also be used to kill cyanobacter. It can be expensive but easier to obtain than eurethromycin and no vet fees. 1 cap/40litres then vac gravel and same next day.

Dave+Amy Posted October 14, 2008 Author Report Share Posted October 14, 2008 cool i got to get some furan 2 anyway (thought they only come in capsules?)...should I still leave the lights out? I do add plant fert everytime I do a water change, should I stop until it goes away? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 14, 2008 Report Share Posted October 14, 2008 Cap = capsule Quote Link to comment Share on other sites More sharing options...
Dave+Amy Posted October 14, 2008 Author Report Share Posted October 14, 2008 Cap = capsule woops I thought you meant 1 cap (thinking liquid wise) :oops: Quote Link to comment Share on other sites More sharing options...
nicmack Posted October 29, 2008 Report Share Posted October 29, 2008 did you get rid of it? my phosphates were out of whack when I got my outbreak so I added some phosvec to the filter to bring my readings down, this can happen when you feed in live food. I got hold of some eryo... to clear it up and it took around 3 days but its gone and didn't come back it didn't hurt the fish either I was really worried about my gold spot ... you just need to siphon it all up as it dies so your filter dosen't get overwhelmed Quote Link to comment Share on other sites More sharing options...
