What type of algae is this?

[Cammywammy]

Here is a picture of it on one of my plants but it seems to be everywhere.

how long has the tank been set up?

Well I redid the tank so not long. Will this algae harm my plants??

 

[Cammywammy]

Could it be diatoms or a type of brown algae?

I have something similar happening in my tank in the last few days. However, it is showing up only on the older dwarf sag leaves. New growth is fine. Algae is brownish, slightly clumpy (looks like sap or honey). Tank is 5 months old, recently rescaped a bit and change of lights (dual t-5 NO to Finnex FugeRay). I am thinking that a change of lighting might be causing the new algae growth.

I have two 18 watt cfls maybe this type of algae is caused by high light. Or it could be from redoing my tank. If anyone knows how this algae is caused or how to treat it please help us!

I believe it may be a combination of all of the above. Rearranging could stir up waste or introduce nitrates into the water column, temporarily disrupt the nutrient uptake by plants...this could lead to an imbalance that the algae might be taking advantage of.

I will try treating with Excel tomorrow for a few days to see if it helps.

Let me know how that goes I may invest in some if it works.

You can also treat with H2O2 but I too have treated algae with excel and it does work very well. What are you using for CO2 in this tank?

Is that Q for me or Cammy? I use Excel although I may try H2O2 (need to check the med cabinet for it).

I have hydrogen peroxide. So excel doesn't kill this?

 

[Fresh2o]

I couldn't find any peroxide so I used excel. Shut off filter a few minutes ahead of time so there would be no current. I turned on the lights for only a few minutes so that I could see what I was doing. Dosed about 4mL (tank is 20 g) on the affected plants (dwarf sag and crypt parvo). Let it sit for about 5 min before restarting the filter.
I'm also treating a second tank as well but for a different type of algae (bluish green slimy mat on some recently planted cabomba).
