How to do a reef tank water change

[tprowse0804]

As an experienced freshwater keeper, I would simply clean the glass and then syphon out water and use a hose to fill it adding a few drops of water conditioner while I'm doing it. But, it seems to be the general rule that salt water systems(especially reef tanks) tend to be more finicky.
My thought is:
Premix a pail of water that is conditioned and salted, then poor it in.
Is this right?

I usually mix it a day ahead... test the salinity and add prime... that's about it! I am sure many people will have a bunch of different ways of doing it! depends on the size of water change. On my 90gl I do a 20% change out. so it's more then just a bucket!

Your approach is correct. It really isn't that much different from fresh water. Remove old salt water add new salt water ( of the same salinity and temperature).

What's with adding Prime? Isn't that for tap-water? Or are you using tap-water?

I would use RO/DI water but some people get away with tap water and prime (depending on your local water).

One thing I learnt fast is to forget about pouring water into a reef tank unless it's a small quantity. Even in my little tank, I do 5 gals at a time and it's to heavy and you have to pur too slowly to avoid stirring up all the sand.

I siphon the water out and pump in the new water after it's circulated for at least a day in a bucket.

yup I use tap water! have been for 5 years! never had a problem! We also use tap water in the store without a problem!

i always add my water into my sump return-that way it doesn't disturb the display

I use tap water as well. I remove whatever water out of the tank. Fill up buckets with tap water and mix in the salt. Test salinity then dump it in.
I have FW tanks too and its all the same, except for adding the salt.

Just wondering, does everyone do water changes?

It's highly recommended, but no, not everyone does. If you choose not to, it's best to have a real reason not to, and know the risks and benefits. Being cheap on salt isn't a good reason
