	% water change and why
keithgh Ultimate Fish Guru Posts: 6371 Kudos: 6918 Votes: 1542 Registered: 26-Apr-2003	What would be the best of these three 10,15,20% water changes for the well planted Betta & Cardinals tank. Filtration Eheim Bioball 2206 10G = 37US G I have read as high as 100% and as low as 10% for Betta even with my experience there is a huge difference here. I assume (and one should never assume) that the 100% would be for the small jars etc. Keith Near enough is not good enough, therefore good enough is not near enough, and only your best will do.

Just figure out nitrates just before the water change and then after the water change and see if your comfortable with the amout your doing.

Just watch for nitrates, but that shouldn't be too much of a problem in a planted tank. I have found that bettas don't do well with higher nitrate levels. ___________________________________________ If at first you DO succeed, try not to look astonished.

Well, between 15 and 30, you make that judgement For animals, the entire universe has been neatly divided into things to (a) mate with, (b) eat, (c) run away from, and (d) rocks. - Terry Pratchett
