Poll - Water Changes

[OrionN]

Once a month. 15 g for a 65 g tank, 40 g in a 300 gal system. 5 gal for a 30 gal tank and 5 gal for a 24 g tank.
Soon I am going to consolidate to a 340 g tank with ~75 gal sump and 50 gal refugium. I will likely change 50 g every month on that system.

Have not fully decided as of yet, leaning to doing 12 gallons every two weeks, that may change once my tank is going.

Once a week. .10g on a 95g..an going to do..5g o. A 70

I have been encouraging cyano growth in my sump using the TV method to keep the DT clean. So far it's working. Or rather, I don't worry about it when I see it in the sump. Just rinsing the food before feeding the tank seems to keep the cyano at bay.

I'm doing twice weekly 5g water changes (Wednesday and Saturday) on the 185 and weekly 5g water changes on the 28g(Saturday). Like Alton, I could only vote once so I went with the twice weekly vote.

We do 5-10 gallons a week on our 40 depending on how things are looking most of the time it's a 5 gallon though. I think I may change to a twice a week program though after reading this thread

I used to do 40 gallons weekly on my 275 gallon system. It's now been about 3 months since my last water change. Nothing's really changed in the system. All parameters are still in line. 5 nitrates, .25 phosphates. 1460 mag, 480 cal, 11.2 alk, 1.026 salinity. No bio-pellets or gfo. Just a decent sized fuge and a additional Xenia fuge with a Kalk reactor. I'm beginning to wonder about the importance of regular water changes...if nothing else, I'm trying to justify my laziness.

my parameters are 480cal, 8-10dkg alk , I don't test mag, phosphates stay .01-.02, 0 nitrates. my ph is a lil low 7.5-7.8 throughout day.

crazy all the diff techniques we use, but each system is diff. reefnub seems to be closest to mine as we both keep lots of Sps and same husbandry

I've read blogs of zero water change systems. And they thrive.

Wish I could find those links again.

I do 1 or 2 times a week 5g
