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.

Algae Update

I thought of providing an update on my tank. For the past two weeks I made the following changes. Every time I make a water change the algae comes back with a vengeance. I added a new plant rotala indica (shown in the picture). Although the plant is growing, you can see the algae quickly developing on this plant. Also, prior to making frequent water changes and using turkey baster for gravel to improve gravel vacuuming, my Amazon swords were free of algae. Now, they are infested with algae.

Here are the changes I made.
First week change:

1. Incorporated turkey baster for cleaning
2. Increased water changed to twice a week (25% each time)
3. Pruned the algae infested rotala Hra

Second week change:
1. I suspected that frequent water change is having a negative effect on beneficial bacteria. So, started adding Seachem pristine after every water change. It looks like there is some change, but the algae growth is relentless
2. Removed carbon and changed to Seachem Purigen

Parameters after water change:
1. Nitrate levels reduced from around 5-10ppm to 0-5ppm. Other parameters are pretty much the same as what it was earlier. That is:
Ammonia 0-0.25 ppm
Nitrite - 0ppm
Ph - 7.6
Phosphate- 0.25-0.5ppm
GH - 50-100ppm
KH - 0-50ppm
2. Light 6hrs, Co2 2 bubbles/sec

Currently, my plan is to introduce more fast-growing plants. I still dont know what mistake I am doing. Even after changing water multiple times (and gravel vacuuming) the algae does not seem to go. In fact, it comes back strong. Any help/suggestion is appreciated.

You’ve got cyanobacteria and also diatoms as well as, maybe a hint of fuzz algae.

What if anything are you dosing for ferts in tank? How often and how much. Doesn’t matter what your N and P levels are if they’re not accompanied by the proper levels of at least a dozen other elements. No iron, plants aren’t going to grow, algae will take over. No Zn, plants aren’t going to grow, algae takes over. No K, plants growth will stall and algae will take over.

Here is a basic list of all elements that plants need to fluorish, you can add Ca to that list but that’s usually handled by change water, but not always.

Target Concentration Levels, at least dose these amounts in proper ratios 2x a week for your plant choices, lighting and CO2.

Also have you measured your pH drop from right after CO2 comes on to right after CO2 shuts off? This will give a clue as to wether your dosing enough CO2.

MACROS
NO3 7.5 ppm
N 1.694 ppm
PO4 1.3 ppm
P 0.424 ppm
K 5.3 ppm (7.5 ppm with additional K2SO4)

MICROS
Fe 0.5 ppm
Mg 0.107 ppm
Cu 0.007 ppm
B 0.061 ppm
Mn 0.143 ppm
Mo 0.004 ppm
S (0.917 ppm with additional K2SO4)
Zn 0.028 ppm

Keep going with the baster and clean up, by appearance your still way behind on cleaning up your DOC levels (dissolved organic carbon). The fact that when you did baster and algae flared up means you brought waste up into water column by doing that.

50% water changes and properly prepping change water and slowly adding change water to tank as well as refreshing carbon every week would be my attack plans. Keep a eye on your Purigen color at least once a week, once it passes from that pale ivory color to med brown recharge/swap it out. At this point I would even consider doing a a blackout/cut co2 for 3-4days and running PolyFilter for a couple days in Aquaclear to scrub water to pristine quality. PolyFilter is aggressive stuff, it’s color change might even give you a clue if there’s some contaminate in water. If it just turn brown that just organics.

Also do you have a picture of whole tank showing filter placement (what size AC filter?) and position? Bad circulation patterns in tank can very much effect a tanks overall biological performance. In certain instances it can be cause of hard anaerobic activity in substrate. Substrate to deep and poor substrate level circulation can very much cause the algae problems your seeing.
