So I have been putting a lot of thought into the automation for my 75. which is now fully cycled. but before I get ahead of myself and make things more difficult I need a new ATO. Ive pretty much narrowed it down to two systems. 1: Go with a Tried and independent system the JBJ. or.... 2: add on to my Reef Keeper lite. and use its ATO feature. Having an ATO on a system separate from my controller seems like it could be an extra fail safe in case something went screwy on the RKL. but on the other hand the JBJ could malfunction some how on its own while the RKL keeps on working. The other factor in this dilemma is that I have been looking to expand my reef keeper to add a PH probe in case I want to run a reactor in the future (and for every day monitoring) So its about $80 to add the monitoring module, and then $40 for the Float switch (+ more for a PH probe), VS the $80 for just the JBJ. I have to buy one or other so I was looking to justify expanding the RKL but I need to look at this objectively to see the pros and cons of each.
