Yoshi Posted May 25 Share Posted May 25 So this afternoon as I was making some adjustment to my aquarium I noticed this growth on the airline tubing connected to the sponge filter. I'm assuming it's some kind of algae? As some background, the setup is very new. Only been running for 10 days or so. I don't have any livestock in it yet. It's moderately planted with some buce, anubias, maybe five stem plants, and a handful of red root floaters and water spangles that haven't really started propagating themselves yet. I have an ACO LED light set at 50 to come on 7hrs a day. I would like to set it lower, but the piece of driftwood I have in there is leeching tannins like it's going out of style, so I turned it up higher to try and get sufficient light to the plants at the bottom of the tank. When I checked parameters last night my nitrites and nitrates were pretty high but I'm still working on the cycle so I wasn't planning on doing another water change until mid-week. Any thoughts? 1 Link to comment Share on other sites More sharing options...
Kunersbettas Posted May 25 Share Posted May 25 Almost looks like hydra and hair algae tried to eat each other. Not sure. I've never seen that kind before. Looks a little too thick to be white hair... 1 Link to comment Share on other sites More sharing options...
PonyPlantedTanks Posted May 26 Share Posted May 26 I have that too. I don’t think it’s an algae but rather some sort of biofilm. I’ve seen tons of people have the exact same thing and it’s always on the airline tubing! Mine comes right off in big chunks if you rub the airline between your fingers. Does yours come off easily too @Yoshi? 1 1 Link to comment Share on other sites More sharing options...
doktor zhivago Posted May 26 Share Posted May 26 It's just biofilm. Snails will clear it up 2 1 Link to comment Share on other sites More sharing options...
JoeQ Posted May 26 Share Posted May 26 (edited) Bio film/bacteria bloom, your tank is uncycled and only 10 days old. You are witnessing your eco system starting to grow. Edited May 26 by JoeQ 2 1 Link to comment Share on other sites More sharing options...
CoryWithAKatana Posted May 26 Share Posted May 26 If you dont want your tank to be so dark with tannins then I would suggest a water change but if you like it then keep it. The algae im pretty sure is natural to a new starting tank 1 Link to comment Share on other sites More sharing options...

Snails will clear it up I don't have any snails in there yet, but I'm planning on having about a dozen once the tank is fully cycled. A mix of nerites and trapdoor snails 🙂 On 5/26/2024 at 7:59 AM, CoryWithAKatana said: If you dont want your tank to be so dark with tannins then I would suggest a water change but if you like it then keep it. Yeah, the tank is SUPER dark right now. I didn't realize that one piece of driftwood would leech so much tannins. Since I don't have any livestock in it yet I'm not too worried about it, but I am doing some water changes. It'll stop being so dark. . . eventually. . . 😄 1 Link to comment Share on other sites More sharing options...
doktor zhivago Posted May 26 Share Posted May 26 snails tend to defy our attempts to control their numbers just leave the driftwood be it will clear up over time and the tannins don't hurt anything. there's no point doing water changes if you don't have any livestock 2 Link to comment Share on other sites More sharing options...

Does the water ever get saturated with tannins? Like, the water can't absorb anymore even though the woods has more to leech out? That's why I've been doing some water changes, to sort of keep things moving. That and I have about a dozen plants in there, and I'm afraid with the tea so dark they're not getting enough light. 1 Link to comment Share on other sites More sharing options...
DBrown918 Posted May 27 Share Posted May 27 Tannins are actually great for fish so it's more of a cosmetic preference for you. They have antibacterial properties and a lot of the tropical fish we keep comes from waters with lots of tannins. I would say change water to achieve the look you're comfortable with and that will provide the plants with enough light. Link to comment Share on other sites More sharing options...

The camera makes it lighter than it actually is. In person you can't even see the back of the tank and you can't see anything looking down from the top.

DBrown918 Posted May 27 Share Posted May 27 Yea that's too much unless you're going for blackwater. Just keep changing water until you reach the level you're ok with. 1 Link to comment Share on other sites More sharing options...

My Barb's love the tannins and the colors are so good on them. 1 Link to comment Share on other sites More sharing options...
