Algae ID and treatment - moving plants to new tank

Hey all, I just got a new tank and transferred over my plants from my old tank. I'm doing a low-tech setup.

Many of the plants I transferred have algae growing on their leaves.

I have shrimp which may eat some of it, but not enough to stop the spread, apparently.

Any idea what kind of algae this is and whether there are good treatments for it?

I've read various pages about treating algae and considering doing a blackout treatment, but wanted to see what the experts have to say before going down that path!

Thanks in advance for any pointers.

Looks like it's probably:

Black Brush Algae, BBA

Treatment guide says:

In a high light tank you will need to increase your levels of CO2 and/or improve water circulation around the plants. Scrub and cut off as much as you can first. Increase levels slowly to 30ppm or more but watch the fish to see if they are respiring heavily. Make sure you have good water flow around the whole tank along with some good surface movement. Adding a powerhead may help.
If you have a low light tank without CO2 injection then not doing any water changes will help. This is because tap water often has lots of CO2 dissolved in it which causes CO2 levels in your tank to fluctuate. The algae respond to this a lot quicker than the plants do.
Siamese Algae Eaters are known to eat BBA so can be used to control this algae.
Overdosing Flourish Excel, EasyCarbo or TNC Carbon will clear it up.

Sound right?

We can give you some short-term corrections, such as a single dose of 1ml / gal of Excel, to knock it down, but the best way to reduce and contain it is a longer-term approach, which involves having the right light, for your situation, in order to establish healthy plants.

If you provide as much of the following info as possible, then we can better advise you:

- 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?
