Hi everyone, my first post here.

I have a 40 gallon tank which is about 6 months old, which is planted with Green Hydrophilia, water wisteria and some bocopas.

I had issues with staghorn algae, and realised I had no additional carbon in my tank, and have moved to liquid carbon options as a way to supplement my tank. Its a quick fix but it worked.

I want to eventually invest in high quality lighting and add CO2, but I still want a healthy tank while I save for this.

Once this vanished from my tank, a brown algae, or something like it, has appeared and seems to be stifling my water wisteria in particular.

I have a bad feeling this might be blue green algae, although it isnt particularly slimy and comes off very easily.

Any ideas?

If it's bga it will smell bad when you wipe it off.

Yeah there's no smell when I wipe it specifically (there is a mild smell in my tank overall though), so I guess it's not that then.

I guess I'll just remove all the "bad" plant material and see if it recovers.

Keep an eye (a nose?) on the small. If it's a really nasty fishy odor it cold be that you have bga (cyano). Normally my tanks smell like nothing or earthy depending on what I'm growing in.

Its not BGA..you might reduce the photoperiod a bit. I think all looks fine..just give the plants time- like Bacopa to develop a bigger root system. It is one of my top stem plants of them all.
