Water Changes

[sayuncle]

75 gallon tank and I change 25 gallons every two weeks.

I have a 150 and I change out 20-25% every month. The 180 we are planning on will be the same way.

 

[ellisz]

180 gal display + 100 gal frag tank + 100 gal sump/fuge.

I do 40 gal or so every 3-4 weeks. I have gone longer but that is what I try to do.

 

[Scottm]

I have a 12 gallon that I change 2 1/2 gallons out of every 3 days or so, I have a calcium sapping frogspawn in there that needs it and on my 55 I change out 12 gallons every 2-3 weeks. My 55 almost never seems to need it but I do it anyway.
