Rolla Posted November 24, 2003 Share Posted November 24, 2003 Just noticed today that i have little specs of green algae appering on the front glass of my tank...It looks crap and i want it gone but first i need to know1 What caused it2 How to get rid of itI think it might be due to excessive lighting, because of the hiurs i work the light go on at 7am and dont get urned off till 7pm or sometimes later if i forget..lighting is 2x40w with 2 plant tubes from prevoius setup..Thanks Dave Link to comment Share on other sites More sharing options...
Mazimbwe Posted November 24, 2003 Share Posted November 24, 2003 You have answered your own question really.12 hours+ of light per day will give you algal growth. The speck-type green algea is very tough to get off and I use a glass scraper to clear the stuff from my tank.Alternatively you could reduce the hours the actual lights are on, maybe start them at 10 or 11am seeing as the sun is up so early and you are not there to enjoy looking at them...why waste the power??Maybe a Pleco of some sort could solve the proble for you without making any other changes.HTH Link to comment Share on other sites More sharing options...
anchar Posted November 24, 2003 Share Posted November 24, 2003 Hi Dave Essentially algae in aquaria need 2 things to grow - light and a food source. I'd say that your light is on for too long so if you aren't growing plants, then cut back the hours of use. Regular partial water changes should dilute nutrients , provided your filtration is effective. Perhaps throw some sucker mouth catties like bristlenoses in to help keep the problem under control. All else fails, a scourer from the supermarket will remove it (not one that scratches the glass). Personally I avoid the use of chemical control as it only seems to cause more problems with the biological balance in the aquarium.merjo Link to comment Share on other sites More sharing options...
Rolla Posted November 24, 2003 Author Share Posted November 24, 2003 thanks for the replies so far guys..I have 5 bristlenose in there ATM but they seem to prefer grazing on the rocks now since i set up the cichlid tank Maybe i should invest in a timer for my lights? what would be the appropriate duration for them to be on?Dave Link to comment Share on other sites More sharing options...
Red Tail Shark Posted November 24, 2003 Share Posted November 24, 2003 i too have the same problem in my tank and i have tried everything my light doesnt get turned on till miday or later i had a pleco plus a dozen suckers and still it came back the only thing i seem to be able to do is use a razor blade to take it off if u have any sucess i would be most great ful to hear about it Link to comment Share on other sites More sharing options...
PHL Posted November 24, 2003 Share Posted November 24, 2003 Best way is to have a heavily planted tank; I currently have 90W over mine, and get very little green spot algae (I clean the glass every 1-2 months on this display tank), so much so that I'm having to feed the BN and Ottos. But it is heavily planted, and I dose fertilisers (including Potassium Nitrate). The plants suck up all the nutrients, and are better able to store them, hence outcompeting the algae.

dviv Posted November 25, 2003 Share Posted November 25, 2003 The algae on the glass builds up slowly, and for some reason not all of it is eaten by BN's/Pleco's. Every now and then, scrape it off with a scraper or a (clean) razor blade. Supermarkets or hardware stores sell scrapers that have a changeable razor blade, and these work a treat. :^: Good luck Link to comment Share on other sites More sharing options...
Guest Gutty Posted November 25, 2003 Share Posted November 25, 2003 Maybe i should invest in a timer for my lights? what would be the appropriate duration for them to be on?Dave You can buy timers at Woolworths for about $8. I believe your fish won't be too bothered how long the lights are off for(assuming your tank isn't in a pitch black room) so have the timer set to come on just before you get home and turn off just before you go to bed. Less growth and more veiwing time for you.Hope that helpsMatt Link to comment Share on other sites More sharing options...

dviv Posted November 25, 2003 Share Posted November 25, 2003 Sorry I just read my post again and it didn't say quite what I meant.I meant there is one kind of algae that they will, and do, eat. But there seems to be another kind that they can't actually get off the glass, it's much harder and actually makes a scraping noise when you remove it. Whereas the soft stuff that they do eat just slides right off really easily (tho I try to leave it for them )hope that makes a bit more sense now.

wazza Posted November 25, 2003 Share Posted November 25, 2003 There are algae solving chemicals out there except from experience i have found that they dont work very well.wazza Link to comment Share on other sites More sharing options...
dviv Posted November 25, 2003 Share Posted November 25, 2003 I tried using some once.... didn't seem to make any difference. Though in a 5x2x2 that's hardly surprising Using BN's/Pleco's, scraping and controlling the light seem to be the best way to keep algae down.
