Water changes!
I usually do weekly water changes to keep the water in the tank as clean as possible. Today is-was a water change day but I jsut tested the water for Calcium, Nitritate, Ammonia, Phosphates, PH, and Alkalinity and everything looks good. So my question is, should I do a weekly water even if the water chemistry seems to be fine.
 Calcium 350 Alkalinity 3.8 dkh Phospates 0.03ppm PH 8.3 Amonia 0 What do you guys think? Should I wait a few more days? perhaps bi weekly water change instead of weekly? Cheers

There's people out there who only do bi-weeklies, other monthly, some never, so might not hurt to experiment, but if what you're doing works... Remember though, even with a protein skimmer, best way to get the crap out of the tank is water changes.
Chk you alk or your units though, 3.8 seem low for dKH but getting up there for meg/l. Usually see 2.5 - 4 meq/L or 7 - 11 dKH. Also see 380–450 ppm commonly quoted for calcium if having corals.

What percentage are your weekly water changes? You might do well to just reduce your percentage if you feel that you've been over doing it.
Another thought, things that we don't tend to measure such as trace elements are replenished with water changes too.

don't fix it
If it's not broke don't fix it...I'd stick with the weekly change [ 10% to 20% ]
I started weekly and have never changed...first time in years I have had to change, this week due to a Ich product going bad...the product I was using has been posted in, you guessed it Products. RJ " Express Lane : Five Beers or Less "
