Hello. I have a well established 20 Tall. It is heavily planted and well, fully stocked for sure. The tank sits beside window and naturally grows some algae. I'm looking to determine how I can go about further promoting algae growth in the tank. I have in the past used the plant grow solutions commonly sold in aquarium and pet stores with great sucess for some plants. But it is really the algae I want to see grow in a little bit more! Any suggestions!?!
