its not done yet, as you can see.

Big thanks to Kevin at Red Coral for the RODI unit, I was on a break from work and he got everything together for me, even though he was busy, he replaced the filters on it, so all i had to do when i got home was hook it up to the tap. Customer service is really top notch.

I tested the tap water again, and it was 170. The water from the RO unit was 000

Sweet.

congrats on going RO!

With RO (and less TDS and other junk) you may want to rethink/tone back your Zeo lest you completely strip the water bare or all nutrients.

Welcome to da Club! :mrgreen:

I don't agree with this...

Why not?

Because I don't buy into "stripped water" anecdotes. If he is currently a successful Zeovit user, his water will already be "stripped" or whatever ambiguous state the armchair elite would like to call it. In recent memory, I can recall a similar accusation pointed towards high efficiency skimmers. As we all know, current skimmer technology succeeds previous incarnations by a long shot. The result? Better, cleaner tanks with healthier livestock.

The key here is to keep things as stable as possible. Reducing supplementation of carbon sources or media beds will have a larger negative impact on a stable system than simply switching to water that should have been used to begin with.

Let's put it this way; don't fix what isn't broken, and this isn't broken :D

That's the issue here - it's not just reducing the supplementation of organic carbon or whatever other zeovit additives that is going to have the negative impact, but the sudden change in overall nutrient availability. You're going from a nutrient rich (tap water) to a nutrient poor (RO/DI) state before bacterial/skimmer/nutrient export processing. Like any balanced equation, if you take one term out (in this the extra nutrients in the water) you're going to have a deviation from equillibrium.

And, I'm quite active. I don't even own an arm chair.

I agree with albert on this. Zeo's job is to "strip" the water as you guys are calling it. The zeo products then introduct their own nutrients to the coral via dosing. If anything John should see better results with a cleaner starting point. (Zero TDS)
