Do I have to do water changes?

Do I need to do a water change if my readings all look really good still? I have had my tank up and running for about 3 months now and have not done a water change yet.

But...my readings are pH=8.3 NO2 = 0 NO3 = 0 SPG = 1.023 NH4=0

So do I still need to do one? My fish, xenia and rock all look really good too. I still have tons of pods too.

80lbs live rock
1 kole tang
1 dragon goby
1 bi color blennie
7 snails
3 hermits
1 sand sifter

what do you all think?

Do you have a LOT of evaporation? Maybe if you are adding enough, it is helping to keep your numbers low.

Water changes are done not only to export waste but also, in SW, to import essential elements that are depleted over time by your tanks inhabitants. Depending on what you have, IMO, water changes are vital. Replacing evap. water does nothing to the water quality. The "fresh" salt in freshly made water is what replenishes the elements. Here's more info http://www.advancedaquarist.com/issu...2004/short.htm

Are you watching how much your SG fluctuates? Evap. water should be replaced daily, especially if it is "tons" like you say. HTH

This topic probably isn't as cut and dry as everyone is making it out to be.

There are people out there that run a perfectly balanced system that doesn't need more than 25% water changed in a YEAR. Infact I've read quite recent literature that states frequent water changes are BAD for the stability of the system. Anyway, most people overstock so they don't really have a choice.

I do think that if you don't do regular changes then you probably should be testing and supplimenting a lot more than just those parameters you stated. As MT79 said, some essential elements will get depleted over time.

EDIT: Forgot to ask if you've verified those test results are accurate?

Even if water tests show that the water chemistry is acceptable, if you are not adding trace elements IMO water changes should be done. I do smaller changes like 10-15% weekly in my 20 gallon. The water changes will export built up wastes in the water, excess nutrients etc. and replenish trace elements, vitamins, minerals etc. Probably not as important in a FO system, but much more so in coral tanks, water changes aid in maintaining proper levels of calcium and carbonate hardness.

I do water changes a lot less frequently as water volume increases. That's why I like my 75g to have 150g of water in it so far with the sump.

My smaller tanks are a lot more frequent.

I believe in the importance of regular changes. i do frequent small changes. Maybe 5-10% everyother week. I rely on the changes to replenish the trace elements that my reef needs. I do not add any reef additives to my tank, just rely on the new saltwater to do this for me. Hope this helps...Lando
