(a) I have heard that the smaller your tank is, the more amount of water you need to change in every PWC
(b) That more fishes means bigger PWCs too.
But reading about and percentages of water changed and frequency, I finally think that everyone has his own "homemade" rule about PWC.
For my 29g aquarium I do 10% every a week, and for the moment my nitrates keep under 25.
But thinking about it a bit more, the truth is that the less often you make changes (but of bigger percentage), the more of the contamined water you substitute.
For example. Is it the same to change 1.4% every day, 10% every week or 20% every 2 weeks?? If you do the last, 48,8% of the initial water will have been substituted after 6 weeks and if you go gor 1.4% every day, only 32.6%. Which is the best though?? Should small everyday changes be a bit bigger??
I wouldn´t like to focus the topic from the point of view that the more you last to do a PWC, the bigger the change abd therefore your system may loose stability, fishes stress etc. My question is:
How can you remove the maximum amount of polluted water by taking out the least amount of it (therefore disturbing the system the least)????
I hope the topic makes sense and that I gave you understand my question...
