cariba and Reds can be mixed, Just try and get them at the same size and add them all to your new tank at the same time. If I had more room Id have them mixed with my reds.

I agree that even at 4:1 ratio of waste to produce is too much to send down the drain. Do you test for TDS with this configuration? According to the research you would have to replace the filters more often because of the increase of dissolved material in the water once it was waste.
I like the idea of rerouting the waste back into the hot line of the house. I was wondering if anyone has had success using a retro-fit zero-waste kit like the ones Watt sells. https://www.wattspremier.com/products.php?product=Zero-Waste-Retrofit-Kit
Without a holding tank to open the switch the pump would run continuously. This could affect the longevity of the pump, but I'm not that concerned about the cost. The model there only uses 14 Watts of power. I could easily find a lightbulb to unscrew to cover the cost of running it, and I will certainly be helping the environment.
Any ideas about retrofit kits?

Cool guys and very healthy stock. They give you the fish in a bag with pure oxygen up top and a live-arrival guarantee. They are in Bayonne NJ so I just drive there.
As for the zero-waste configuration, I calculate that running the RO/DI filter would cost about 55 cents a day in wasted water--under the best operating conditions, more as the filters wore out. The environmental impact is hard for me to stomach too. The zero-waste pump would pay for itself over the course of 14 months if I was running the system continuously. It would take longer if I was only producing RO water for four hours a day-- a length of time which would replenish the water more than 35% during the course of a week. At that rate I'd have to expect the pump to last over five years to recoup the cost of lost waste water. Then again, saving water is about more than saving money to me.
I'm going to see if I can incorporate a time-operated solenoid valve to automatically run the system during the night for water changes. When I figure out the final setup for the plumbing I'll make a diagram to explain it all.
It seems that according to the literature a RO membrane will lose about a third of it's lifespan if the discharge/waste water is allowed to re-enter the system. The unit will produce clean water, but won't last as long. A third of the life ends up costing about $80 a year in extra replacement costs for the Kent System I have purchased. I would be able to recoup that difference in just under two years with the zero-waste pump. Any additional life I got out of the pump would only add to the overall savings.
Cheap -- let the water run down the drain
Inexpensive -- hope the zero-waste pump lasts a long time
More expensive -- run the waste water back through the RO membrane
Hope my research helps.
