amen!
So far three people in this newsgroup do little or no water changes at all,
you, blackhole..., and myself.
It is true what you say, it is just lack of knowledge.
My system is similar to blackhole's except that I don't add any supplements
but I will start using them after seeing his tank.
I use Rowaphos for the PO4 and my circulation system is producing a lot of
debris with lots of PO4.
As soon as I change the lighting system, T5, I will post some pictures here.
See, the three of us have some level of knowledge on science. This people
rely on LFS for their decisions, feel sorry for them, lol

Might be better to stand the question on it's head and ask those who do
water changes "what do you think they achieve". I don't need to remove
NO3 (It varies between 0 & 5ppm) or PO4 or anything else I can think of
right now. If adding trace elements is your reason, then you're
assuming that the salt mix you buy has the correct trace elements in it
(Some don't event get the Ca & alk. right).

I have been arguing with these nuckleheads for about 2-weeks regarding
unnecessary water changes. I have received 3-reasons that they do them.

1) In order to add trace elements/remove nitrate.
2) It's enjoyable
3) Because coral release toxic chemicals into the water ??

I think the real reason they do it is for a lack of understanding at the
chemical/biological level. It is easier for them to do a water change
than to grasp what is going on in their tank at a biological level.


BTW: It's not laziness either, I also have 4 FW tanks & they get 20%
changed every 2 weeks. Anyone got any live rock that works in FW?
