Default RED ALGAE

Its not a BBA...its like a slime almost....or a flat type of algae on the front glass...


So now it's red, flat and slimey?
Are you sure it's not Blue Green Algae(BGA)? Or Cyanobacteria as some
enjoy calling it. It's not red in color as a rule in FW.
There are only two species of red's that commony occur in FW plant
tanks.
BBA and Staghornm, both are easy to see the branches and filaments.

If this sounds like the BGA algae, then a blackout is the best method
to get rid of it. Remove all you can and scrape the gravel line etc
with a plastic credit card etc. Vacuum up, use a net etc to remove all
you can first.
Trim tank, trim down any plants near the water surface. Clean filter
etc.

Then do a 50% water change, turn of the light and CO2. Cover so that
100% of the light does not get in. Add enough KNO3 to get 5-10ppm of
NO3. Wait three days.
Remove cover, do water change again, add KNO3 back and keep up on CO2
and nutrients in the future. It will not come back if you do this.
