I am going on a three week vacation at the end of the month and would like some peace of mind. I have not left the tank for any extended period of time since I started the tank, and with all the coral and livestock, I want them to make it. Anyway, I was looking at purchasing the reefkeeper lite (I dont have too much money to spend), it includes:\r\n\r\nLite Head Unit\r\nPC4 Powerstrip\r\nSL1 Input Module\r\nSID USB interface\r\nTemp Probe \r\npH Probe\r\nmounting screws\r\nI also would like to get the float kit for A.T.O\r\n\r\nMy question is, can this kit plus the float kit and a salinity probe do everything I want it to do.\r\nI would like it to track temp, pH and salinity, control ATO, lights and pump. It would be cool but not required that it has ability to access the parameters over the internet. If you guys think this system would be ample for what I need it for and has the possibility to upgrade or mix and match accessaries, let me know. Any input is welcome!
