Before you can learn how to remove the algae, you must first determine what type it is. There is a good guide to common algae types here. Once you determine the algae type then we can help you figure out how to remove it.
If its heavily infested the best way is to remove the entire leaf. Majority of the time it encourages new growth anyways. For stemmed plants I find it easier to discard the entire stem. It really depends on the plant and the type of algae has attack it though. If its a mild case, gently rubbing the leaf will loosen most of the algae. A good way to fight the algae is to give the plants a jump. Upping the co2 along and nutrients can help once you find the sweet spot. Not sure what livestock you have to control algae but shrimp or fish can definitely help. I prefer RCS over Amanos, ottos are always good to have. I'd steer away from SAE's though. The older they get the less effective they are. Plus they get a tad aggressive IME. Depending on tank size larger sucker mouth catfish are beneficial.

I have 1 otto and some amanos in my 10 and they do such a good job of keeping everything clean. I dont see ANY algae. I think amanos are best because they eat anything and are hardy but they are not the best looking shrimp imo
Also leave your light on for a shorter period, feed less and try more water changes.
If it's mild, rubbing your finger gently along the leaves can generally remove most of the algae. If more tough, could try scrubbing it with a soft toothbrush. I've heard of dipping plant leaves into a bleach solution but you'll probably want to research that more before starting. If it's BBA, could try locally dosing some Excel to kill it off.
I had a bad bba problem and I asked on here what to do. Someone suggested that I spray H2O2 on the leaves and leave it for a minute or 2 and then rinse. So, Sunday I took out all my plants and my fish and drained my tank and treated the inside with H2O2 and cleaned all my plants. I cut off what was too badly covered and then sprayed the peroxide on some plants. I rubbed off what I could rather than using the peroxide on everything. My lacy java fern was horrible. It was literally black along with the driftwood it was on. I sprayed it and left it for about 2 minutes and then filled my sink with cool water. It just rinsed right off!! I was actually able to salvage that plant when I thought I was going to have to toss it.

My tank now looks really nice and algae free. Unfortunately I had to throw away about 1/2 my plants but hopefully everyone in there is happier now.

Good luck!

Hello Jim...

I use Ramshorn snails in all my planted tanks and have no visible algae. They're second to none when it comes to cleaning the plants and removing any other decaying fish and plant matter.

They come in several colors. I have brown, clear, red and have seen some white hybrids in the tanks. They stay small, about the size of a dime and don't damage healthy plants.

A few of these and within a month or so, your algae problems are solved.

A word of caution, they're fast breeders. But, if you feed just two to three times per week, just what the fish eat in a minute or two, you don't have another problem with them piling up in the corners of your tank.

There are many different ways to remove algae from plants, but to offer the best advice, it really is important to know which algae it is. There are different techniques for removing algae from plants, depending on which algae is on them.

Be careful with the suggestions of using H2O2 as it can kill vals. Vals are also highly sensitive to Excel.
