Curious

I'm currently dosing excel every other day and flourish once a week with my water change. The first two pictures are the state of the anubias and java fern before I rubbed the growth off, and the following pictures are what remains after I finished removing the growth. I'm not able to remove all of the algae, and the dark green spots remain on the leaves regardless of how much I try to remove it. Any ideas what this could be?

I think the brown stuff is diatoms, but what confuses me are the dark green spots left over and the mossy-like appearance of the stuff in the first picture. Part of it also turns a little white after awhile unless I remove it...

have you tried spot treating with hydrogen peroxide? or excel?
A lot of people recommend that on here for a lot of different types of algae. how long have you had the tank? Are you doing ferts? what kind of lighting? how long do the lights stay on per day?

I'm treating it with flourish weekly and excel every other day. The lights are on for about 5 hours a day. This tank is pretty well established, cycled, and has been going for about 8 months. Not running Co2 though (I just have anubias, java fern, and water wisteria). What exactly is meant by a "spot treatment" with excel? Do you submerge the syringe in the tank? I want to be careful to not over do it since it's only 5 gallons and I have a moss ball too.

flourish from seachem is micro nutrients only as far as I know. You are missing Macro nutrients. Yes, I mean using a syringe for spot treating
I'm learning about balancing everything as well. But, finding that perfect balance of light, ferts, and co2 seems to be the trick to low amounts or no algae in a tank.

Also, if the tank is receiving too high of light, it could cause a lot of algae problems. What type of bulb are you using?

I'm using a 6500K 15W bulb. Next time I dose excel I'll try spot treating with the excel I suppose. I also got a nerite snail today so I'll see if it helps anything.

Yeah snails do an excellent job Ultimately though finding the cause of the imbalance will save you grief down the road.

Hope I helped

looks like a double dose lol You have Green Spot Algae and Black Beard algae. higher co2 / better water flow, and an increase in phosphates will deal with both. (first for BBA, second for GSA) The brown stuff is Diatoms, they will go away on their own unless your water has high silicates in it.

Thanks for the input so far. I don't think I can do more water flow since I have a betta and too strong of a current makes it hard for him to swim. I don't really feel like investing in a Co2 injection since my tank is pretty low tech. However, I have noticed my nerite just found the tank walls and is pigging out, so I'll see how that works out too :P
