HI,
I am going to throw something out there and am really interested in people honest opinions.
I run a large system around the 1500lt (400g). I do a 250lt change every 3 weeks with Natural salt water.
I had a very experienced reefer come look at the tank and he asked what numbers I keep, I told him
my numbers, two of which are
Nitrates 0
Phos 0.03
He said "oh, so no water changes for you then "
I was suprised at this comment and asked what he meant, this was his answer. Just remember hes been reefing nearly 20yrs (very successfully, stunning tank)
Water changes every week were around and recommended before they had reactors and dosing products, it was the only way to keep parameters stable
. Now with GFO and phos removers, marine pure, seachem matrix for nitrate removal and tons of commercially available Alk /cal/mag for the big 3, plus trace elements in bottles that are created with huge laboratories over years of research, why do we water change.
We water change because everyone tells us too, not because it needed ?
I had never thought about this, we had just always done changes because we have always been told to right from when we started ?
His suggestion was that if your dosing, you only NEED to water change if you have excess nutrients ?
Do we waste a ton of money on salt that we don't need ?
I know with the 6 footer we ran on Red Sea Coral pro (very expensive here $150.00 for 3 water changes)_, we were slack and once went 17 weeks without a change and still had no excess nutrients.
The tank did not seem to suffer ?
Cant wait to hear peoples thoughts on this ?
Is he right ?
