I have had my reef tank for 3 years now and the last year or so I've been doing weekly water changes. I have 90 gallong tank and I usually take out 15 gallons each week. I have to say, it's a lot of work! I used to do water changes every 2-3 weeks or so and take out more water but I've read that it's always better to do them more frequently. I would like to get back to doing it less frequently, but I don't want to mess with anything since my system is used to weekly. I was thinking I would gradually get back to once every 2 weeks. Any suggestions?
