I know, I see the price of corals and fish. I'm like 2 grand into this project with no livestock yet. I was lucky to already have a 40g breeder and stand, so at least that saved a few hundred dollars. And, I still 'need' (want) an AWC. Even with no live stock the ATO was a godsend. Going from 'meh, I can top it off tomorrow' to the water being at exactly the same level every time I check it was great. And, I already ran all the tubing into my basement below the tank, so it's just a matter of finding a pump and not impulsively spending a grand to put in an Apex/DOS. My LFS guy mentioned something about ecotech putting out a controller in the near future so I'm using that as my excuse to not buy an Apex. OTOH, as has been noted many times on the forum, the versa pumps are hard to come by. I have to check my LFS though. I just picked up the Tunze 3155 there and it's out of stock everywhere.
