What type of algae is this and what should I do about it?

Hi all,

I have a tropical 260litre community tank (1 golden gourami, 2 dwarf gourami, 3 small silver sharks, 5 serpae tetra, 2 platys) with a couple of established plants and a fake rock. Gravel substrate. About 4 months old. All doing well but having a problem with brown/black algae of some type (brown/black with green tendrils I guess some photos attached). The tank is out of direct sunlight but I do keep it lit for 11 hours a day. Fish are healthy but the algae is starting to be a problem (I've always let it grow on the rear walls of the tank as the fish do seem to nibble on it from time to time). The algae is all over my plants and I fear will kill them off.

I do 30 litre water changes weekly. Water quality is fine although I have highish nitrate in my area. filter is the standard one that comes with the jewul vision 260ltr tank.

Any advice? Pretty sure i'm not overfeeding as i'm relatively lightly stocked for the size of the tank. Only thing I don't do is clean the gravel.

Some pics attached.

Thanks in advance for any advice,


Richard

photos are blurry but looks like the mighty BBA. does it look like fuzz or does it look like single tendrils? If its black it could be bba if its fuzzy/hairy and staghorn if it looks like a bunch of long thick tendrils that branch off.

Both are caused by chemical imbalance in the tank so you should probably start vacuuming your gravel since the excess organics are probably causing excess nutrients and promoting the algae. The 11hr light is quite long too so you should cut that back and see if it helps any.

Definitely fuzzy although there are green tendrils coming off it as well. Looking at other articles it does seem likely to be the BBA. Think a good cleaning of my plants, rocks and tank is in order and some regular water changes to try and get the balance back. Oddly this has only become a problem as natuary light levels have decreased in winter and wasn't an issue in the summer... Probably will reduce lighting duration as well.

Vaccuming the gravel will involve me buying a longer syphon tube Teach me to go for a bigger tank. As I'm fairly low stocked may look at other algae eaters as well although my big platy loves the stuff but can't eat enough of it.

BBA is eaten by very few fish, i didnt know platys ate it.. A good solution is to remove the infected leaves and keep up with the water. Testing is absolutely necessary to ensure that you do not have an excess of minerals. Some articles i have read suggest that low CO2 and/or low circulation also promotes BBA growth.

What type of lights do you have? It could be that you bulb does not support the entire spectrum for plants and the natural light was supplementing it and now that the light is reduced your excess lighting is promoting algae growth.

The new super long gravel vacs are very pricey, i personally just spent 50 dollars on one, but they are well worth the investment, keeping your water clean and algae low while saving time is totally worth the investment in the long run.

I'll look at the relevant test kits. Got basic testing strips and those show no particular problem with nitrite, KO3 hardness or pH (7ish).

Lighting is standard Jewul "high-lite" stuff without reflectors with the tubes that came with the kit. Can't see anything specific from their site about spectrum of those bulbs.

circulation in my tank should be good and have the outlet from the filter giving a reasonable disturbance of the surface water. Plants grow really well in the tank and very fast. However the algae is taking over at the minute.

test strips are notoriously unreliable, i would take those results with a grain of salt and see if you can take your water to a LFS and have them test it for you. Many bulbs in fixtures that come for plants have a spectrum written on the bulb itself, yours may be written there.

Cutting back lights might help, but regardless of what you do, you will need to remove the affected leaves on the plants and scrub the affected rocks, to try and remove as much of it as possible. Most algaes really capitalize on nitrates and phosphates in your water, phosphate testing is hard to come by at least i havent really seen kits readily on sale, but nitrate tests are very common, you may want to pick one of them up, they are fairly inexpensive and last a long time. Many on the forum use the API Master Test Kit, which will liquid test for ph, nitrate, nitrite, and ammonia. Additional supplements for the kit have GH and KH tests. Prices are usually around 25-35 dollars per kit and an additional 5 for the GH and KH.

Water disturbance at the surface is different from overall circulation. When i had BBA i found most of it to be hear the underside of my HOB filter lip and on decor furthest away from the output, both those locations get minimal circulation since HOBs have a tendency to recycle water they clean. Take a look at the locations where the BBA is worse, is there a defining pattern? If its just everywhere then its not an issue of circulation.
