KyleKVK Posted June 19, 2021 Share Posted June 19, 2021 (edited) This is kind of gross, but I have just discovered a slimy type liquid on the underside of the glass where my light sits on top of my glass lid. A quick google search says it’s something called “Cyanobacteria”? I don’t know anything about it and would love any advice on what to do.

xXInkedPhoenixX Posted June 19, 2021 Share Posted June 19, 2021 Honestly, just clean your glass lid periodically. All sorts of fun stuff grows on it. I've got a thick carpet of algae if I let it go too long. Also, Mystery Snail eggs I need to take down before they hatch on the regular. 4 Link to comment Share on other sites More sharing options...

Is there anything special I should clean it with? Link to comment Share on other sites More sharing options...
DaveO Posted June 19, 2021 Share Posted June 19, 2021 I would simply scrub it off in the tub or sink. Link to comment Share on other sites More sharing options...

DaveO Posted June 19, 2021 Share Posted June 19, 2021 Don't use soap or bleach, just water and a brush. Link to comment Share on other sites More sharing options...
H.K.Luterman Posted June 19, 2021 Share Posted June 19, 2021 (edited) I had a thick coat of slimy algae growing on the underside of the lid on my 29, and it eventually got so heavy it peeled away and fell into the tank. The snails loved it. Edited June 19, 2021 by H.K.Luterman typo! 3 Link to comment Share on other sites More sharing options...
Jungle Fan Posted June 19, 2021 Share Posted June 19, 2021 (edited) From the way it looks, I would say it's just green algae that likes to grow in very well lit places. If it's slime you can just wipe it off, if it's green spot algae that will require a bit more muscle and a toothbrush for the plastic parts while you can take the lid to the sink run just enough tap water to keep it wet and eliminate the green spot algae with a kitchen pumice stone that is usually used to clean glass and ceramic stove tops. Make sure to rinse it off well enough afterwards. Five minutes of scrubbing at the max, and your lid will look like new. Cyanobacteria which is the correct designation, or more colloquial and incorrectly blue green algae, likes to show up on substrate and plants when water values are majorly off, Hopefully I'm correct in my diagnosis because if you can smell it and it is cyanobacteria, and actually looks deep blue green you've most likely got a bit longer campaign ahead of you.These links might shed more light on it for you: https://diffzi.com/cyanobacteria-vs-green-algae/ https://www.thesprucepets.com/cyanobacteria-blue-green-algae-1378628 https://homeaquariumguide.com/how-to-get-rid-of-green-algae-in-aquarium/ PS: Forgot to mention the pumice stone will also take care of any lime residue that can sometimes look like it is etched into the glass and will once again make it look all shiny and new.

lefty o Posted June 19, 2021 Share Posted June 19, 2021 condensation, and light makes that a prime place to grow algae etc. 3 Link to comment Share on other sites More sharing options...
Tanked Posted June 19, 2021 Share Posted June 19, 2021 A toothbrush for the hinge side will help. Mine never gets heavy enough to fall off, but it definitely darkens the aquarium. Link to comment Share on other sites More sharing options...
Streetwise Posted June 19, 2021 Share Posted June 19, 2021 I had fewer issues with my one tank with a lid when I took out the plastic hinge for the front piece of glass. That change allowed more humidity to escape. 1 Link to comment Share on other sites More sharing options...
Cherie Posted June 19, 2021 Share Posted June 19, 2021 (edited) I use tank water and a magic eraser sponge - the snails eat it after it falls in the tank. (The algae not The sponge) 😂 Edited June 19, 2021 by Cherie Link to comment Share on other sites More sharing options...
