Which is better?

[stumpy08]

I have a 54 gallon tank with 4 fish, 3 snails, and a few softies. I have a skimmer, hob filter and a uv light.
Which do you think is better:
10% water change once a week or
20% water change twice a week?

Do you have any powerheads?
Whats the water readings?And whats tested for?

You need to find what works best for your system. I do a 10% weekly. Just because it's easy, and my nitrates are always 0 in a heavily stocked tank.

{Do you have any powerheads?} Yes, I have 2 - 1200's and 2 - 400's
Its has been at least 3 years since I've checked with a test kit. Everything was always were it should have been when I tested so I kept doing everthing the same. (feedings, water changes, etc)
I always seem to get busy in the summer and I was wondering if it would be easier to do a water change every other week as opposed to every week.

Hmm.Its from your water testing you get the best idea of water change amount and scedule. If readings like ammonia and nitrate and phosphate stay low or better yet zero and calcium levels dont drop to much with 10% a month then your good. If fish or coral health are poor or readings staedly rise then more water changed out or the time between need to be adjusted.
