I started a thread in the DIY section and got some advice about small filters. One member suggested the Aqua Clear Series vs. Whisper. Whisper is what I was thinking of buying, but after reading the post I am going to look into the Aqua Clear filters.
There are products to control algae, but since you have some shrimp in the tank you need a certain amount of natural algae. With the stock lighting that you have the plants that you can keep are limited. I have stock lighting in my 20 gallon long with my White Cloud Minnows and the only plants I can keep are "floaters" - easy to keep low light plants which in my case are Java Fern, Java Moss (which shrimp love and thrive in) and Hornwort.
