Can someone please ID this algae. Is this just brown algae (diatom). This seems to be growing unusually fast for diatom. If I brush it off the leaves it goes off easily, but comes back and spreads really fast within days.

James' Planted Tank - Algae Guide

If you would like to have us look at your situation, please post - Light (make & model): ideally, PAR and PUR reading at the substrate and photoperiod?
- CO2 setup (if any) and, if you inject CO2, what is the CO2 ppm level and how is it measured?
- Current NO3, PO4, GH, KH, pH and TDS readings?
- What you are dosing (product and quantity) and how often?
- Substrate type and how long has it been in place?
- What is your filter setup?
- Cleaning regimen (filter and water change frequency and amount)?
- Circulation: surface rippling and are all plants gently moving from top to bottom?
- What is your water source and do you use a water softener?
- What is your tank size?
as much of the following info as possible:

Thanks for the reply. I don't think this is BBA, as mentioned by the previous user, this is brown algae. For the past week or so, I started making frequent water changes and there is some effect on this diatom algae. The nitrate level was a bit high, albeit well within what API instruction says (not sure if this is too much for my tank).

Here are the tank settings:

Tank Size: 45Gallon
# Fishes: 18, 10 serpae tetras, 5 Kerri blue, 1 Angel and 2 German blue rams
Cleanup Crew: 5 nerite snails and 4 otocynclus
Beamworks Beamswork DA 6500K 0.50W,
Co2 - running about 1 and half bubbles per second.
Gravel - floramax planted aquarium substrated. Not a great one I guess, got it from petsmart.
Filter -> fluval aqua clear
Water changes mostly once a week. If there is increased algae, I do twice a week.
Plants - Staurogyne repens (srepens - for carpet), Amazon sword, Java fern, monte carlo (Micranthemum), rotala Hra ('Vietnam Hra) and Egeria Densa.

Parameters:

5-10 ppm nitrate
Ammonia 0-0.25 ppm
Nitrite - 0ppm
Nitrate - 5-10ppm
Ph - 7.6
Phosphate- 0.25-0.5ppm
GH - 50-100ppm
KH - 0-50ppm

Id say waste management is your biggest problem.

Get a turkey baster, go around tank and puff across substrate and between decor to get waste blown up in water column so filter will pick it up, let filter work for 30min to pick that up then right before you do water change have at it with turkey baster again to get as much as possible stirred up in water so it will get pulled out with water change. Change water and then clean filter pads 15min after that so filter has picked up some more floating waste.

After a few weeks you should see algae start to wane. Make that turkey baster usage part of your normal water change routine.

Thanks for the tip, I will incorporate this technique.
