I am just starting to find out how beneficial water changes are, every time i do a water change, things happen, i get new growth and my polyps stand up and everything looks great, what is the best frequency, 10% per week or 20% every 2 weeks? i have a 34G 2 12G's and a 55G which i am currently cycling, so it's a lot of work but well worth the effort.
