Protein Skimmer for 20L

[canadianbudz604]

In a 10g the best thing to do is the weekly water changes. Taking out 2 gallons a week is nothing. takes me 5 mins to make the water 2 nights before, and 5 mins to change it. Havent had a single thing die in my tank yet. the one time i had problems with my frogspawn, it was because I skipped a water change. For what its worth, it would probably take you just a long to clean out the skimmer every week.
