Jave Fern in a 50 Gallon

"To date, your site is the best I've found on what is the difference between a seller's pitch and what is really needed in the real life, with the explanation why. Bravo ! "

"Thank you so much for such a quick response!! I took off the impeller [from the power filter] and cleaned it good. I didn't even know about that. I thought I was going to have to replace the whole pump. But it is working great and the tank is so much clearer. Clyde seems happier too! Thanks so much for your help."
