what about Zebra Barred Dart Goby? I have heard good things about them.

For schooling fish, this^Anthias if you can feed 'em, Chromis if you can keep 'em. :lol:
Now, this doesn't prevent your RODI from overfilling the top off reservoir and/or staying on if the Osmolator were to completely fail. The solution to this would be put a solenoid valve on the RODI and have either the Apex or a separate timer control it to power on for ~30 minutes per day. This would allow the top off reservoir to fill each day but limit the amount of available water if the top-off pump or device should fail.
Brett, here's a thread I posted a while back detailing how I dealt with that problem:
DIY R/O control
I need to post an update, since I made some improvements to the design.
Good solution Mike. I think I'm following this correctly but... is this system a more robust solution to a plastic float valve that one would put in their top off reservoir so the reservoir doesn't overfill? So the RODI unit switches off once the reservoir is full correct?
I guess I was trying to come up with a solution that would limit the fill time per day via a timer/controller and solenoid valve. Which would be a failsafe if the top off controller to the sump should fail in the ON position. Have you done this before?
Yes to the first question. The way this works now is that there are dual float switches in my R/O storage tank. At the "low water" indicator, the solenoid opens and fills the vat to the "high water" state, which then signals the solenoid to close. The design principle is to minimize the number of times the R/O must start, opting for infrequent "fill-ups", rather than more frequent "top-offs". I'll take some more pictures today and post em up.
As for the second question about top-off failsafe to the sump: I'm using a second dual-float switch ATO controller for that. It is set up in the traditional manner: the first float switch (normally submerged) signals the top-off pump to activate/de-activate based on sump water level. The second float switch (normally dry - above water level) is the failsafe killswitch to the top-off pump. Clear as mud, right?
Brett....in the final stages of pulling the plug and buying the Apex. Do you feel it is a good overall investment now that you have owned it for a while? And, is it very hard to wrap your brain around programming and using?
Giving the fact that my maintenance room is in the basement, I would control my: chiller, heater, Calcium Reactor, monitor pH & Temp and ATO all from downstairs. And then run a Cat5 cable to the display upstairs to run my lights and (2) MP60's. To be honest I am a bit concerned about the learning curve and do not want to be fighting with it for weeks, etc. Not to mention the $700+ expense to get the Apex and all the necessary accessories.
Many thanks for any help......Tony

That sounds really cool! I run my vortechs in lagoon mode and agree that sometimes the low flow almost feels like it is off. That WXM module might be my next purchase, once the bank recuperates from the spending I just did...

My dilemma is I have a remote location with all my equipment in my basement. Obviously my light and MP60's are at the display. So I have to purchase extra gear for the display and run the main unit in the basement. Not to mention, I have to run some cabling to and from the two locations. So it is a bit overwhelming and deciding if it is worth all the work and pretty good dollars too.
TIA.........
What do you guys mean when you say ¨schooling fish¨ sorry for being such a newbie but never heard of something like this.
Anyone cares to school me ??
