Question about dosing

[Kaleb W Bellamy]

I just got a doser and was wondering with this how often will I have to do water changes? If at all ??? I currently do water changes every Sunday. If I was to do a water change with the doser how would I go about doing it? I also need to say I have a 125 gal with alot of coral mostly LPS but I do have about 6 Acros. Any advice will help.

It depends on what was your purpose of doing water changes Nutrient control or elements?
I've personally never done a water change on my tank full of Nems, and LPS, and a hand full of SPS. With that said I feed very light and dose ESV B Ionic 36 ml Alk, 36 ml Ca, 1500 ml BRS Kalk, 12 ml ESV B-Ionic Transition Elements, and 4 ml AcroPower daily.
Everything is growing and looking awesome.

Thanks alot that help. So I was doing them for the elements. I feed sea weed and I break up I cub of fish food for 3 tanks so I guess I feed light as well. So hold off on water changes until it's a Dire need?

Are you testing for Alk, Ca, Mg, PO4, and NO3 and if so what test kits are you using?
Personally I use Hanna Checkers for Alk, & PO4
Salifert for everything else.
ATI ICP water test as well. Just keeps my test kits honest and gives me info on other trace elements. Personally I will only do this about every 6 months unless I see a big change in my tank or the results show something way off.
Don't dose what you can't or don't test for.
