And one more quick question. I want to have an algae filter in my 55 gallon reef tank. Would I be able to buy two 10 gallon tank, take the sides off of each one, and then glue them together to make a 20 gallon tank? And also, there is about a 4-5 ft height difference between under my tank, and the top. What GPH pump should I look into getting for the return line? Im not looking to make a lot of current, because my tank already has plenty. Now im thinking, would I be able to take the side off of only one tank, glue it to the other 10 gallon tank, and drill holes in the side of the 10 gallon that i didint take the side off of. And, should I use PVC pipeing, of flexible tubing? What size holes should I use? Sorry, its not really one "quick" question.
