I have penguins and use a python too; I do what HappyGoldfish said. What I do is rotate the cleaning of the filters. I have two penguins on my 55 gallon (330's--so that's a total of 4 filters). I have them numbered 1&3 on the left side, 2&4 on the right. I take sponge number 1 out and rinse it good with the sprayer, the next week I do sponge 2, etc. I also numbered the filters on the other 3 smaller tanks and do it the same way.
