SPS water for softies water change saves salt?

[Steven Pro]

Anthony, please help me out a little further with this.

Other than chemical warfare, I can think of trace elements out of balance when the water from the SPS tank enters the softies one as exchange, i.e. depletion of some of them, and excess of some others.
Am I on the right track? Am I missing some other important points? Which ones?

Lets say the SPS tank is OK on calcium, alkalinity, nitrates, phosphates and all that stuff a regular guy in the hobby can check with conventional kits.
What would the dangers be? just the things we can't check?
you don't need to go into details of course, I just want you to point me out in the right direction if you don't mind

It's clear to me that one shouldn't do it, but I would like a little more info on the dangers if you have just a few secs?

Thanks again!

Hon

This is an old thread, but I just found this:

http://www.tropicorium.com/low_tide_1.html

Here at Tropicorium we make 20 percent waterchange at our SPS vats about every two months. Their waste goes to our soft coral culture vats.

Does anybody know if Dick Perrin at Tropicorium still uses that practice?
I don't see him mentioning processig the waste water in any way before it goes from the SPS systems to the soft corals system.
Maybe ozone?

I mean...he uses (used?) it in propagation vessels, not even displays.

The only thing I can think of, is that with sales the systems receive a much bigger water change than just 20% every two months.

Even so, the SPS waste water goes to the soft coral system, the waste water from the soft corals goes to the fish only systems, and that waste to the brine shrimp system.

He also mentions the Clevelanda Aquarium using that practice, being the octopus display the one that receives the best water first.

It just caught my attention, that Tropicorium uses waste water as per above, and in PROPAGATION vessels.
One would think that in propagation, that would be an even bigger "no no"?

Monoculture vessels, etc...what's the purpose of keeping separate systems, if you are not only mixing water their after it, but waste water on top of that? I mean in the case of Tropicorium.

Thanks for the input.

Just like a dishwasher, washing machine, or any number of other applicances, the RO process uses water to clean itself and make the actual RO water. The "waste water" (i.e. the not-RO water) is not waste at all -- unless you let it dribble down the drain like many folks unfortunately do. I use "waste water" to do laundry, water the plants, etc.

If you just let it run down the drain, it is awful waste.

My flowers dies and lawn turned brown after a few weeks of watering them with my waste water.

I once washed my car with the waste water too. Looked dirtier then before I washed it with all the spots and crap it left behind. Never again.

Down the drain for me.
