Ok guys, I know this has been asked before, but I searched, and I could not find the answer. Is it better to do a weekly little water change, or a monthly big water change?
:happyfish :notsure:
depending on what you have in your tank. I have had my tank running for about three months now and I just did my second change. I don't really do a monthy or weekly water change. My approach is to change as my paramiters change.
I wouldn't recommend this but I have a friend who has had a reef for about 1 year now and has never changed the water. Never had anything die on him.
If you do weekly changes, there is less chance of trace elements being used up and less chance of pollutants to build up over a months time. My opinion, not based on any facts, but it makes sense to me. I do 25% each week.
I think a lot off it has to do with your system and it's bio-load.
