I have a 29 gallon , filtration consists of two 20 gallon 40 whisper powerfiters, one rotating power head and a Aquarium systems skimmer (up to 100 gal) I have been thinking about changing it all to a sump. I am forever cleaning the filters because they dont have as strong of flow as when they are clean. and i really need current on the top of the water because i have a film that i have been trying to get rid of what does anyone suggest. which is better i have ten gallon that i could use or is there a cheap yet well filtering sump that i can buy??
