I bought I Waterbox Clear Mini 16 this holiday. I am tying it into a soft coral/LPS system which is about 90 gallons total. I was planning on drilling the tank and connecting it to a common sump. I am having thoughts that I don't want to drill it and was thinking of a creative way to get water from the system to the mini without drilling it. I was thinking about the biotope that the mangroves live in and about the tides. My thought was to make a tide system that would slowly add and remove water from the tank 2x per day like the tides. I thought how might I do this and came up with this solution and I would like some feedback as to if it would work and potential pitfalls that I have not thought of. My idea is to use two BRS 50ml per minute dosers on a smart wifi plug that has the ability to have timers. I would use one doser to remove water from the tank over a four hour period and add it to the sump, this would be 12 liters (approx. 3 1/4 gallons). After that the second dosing pump would add it back over the four hour period. So over a 16 hour period the tank level would rise and fall throughout the day. The eight hours at night the water level would stay the same. I don't have to worry about the water level in the skimmer chamber because it would stay stable. I dose kalkwasser daily so I don't have to worry about my salinity through evaporation. Also the ato would kick on twice during the day at high tide in the tank, low tide in the sump 2x per day and at night. I evaporate about a gallon a day on the system with a water volume of 90 gallons I don't think salinity swings should be an issue. It is a priority for me that the it is a clean look. I am using a black wire rack to hold the aquarium so everything is very open, the tank is close to the sump, so I should be able to keep the setup looking tight and clean. What are your thoughts? Is it a worthwhile endeavor or and over complicated idea and I should just drill the dang tank? I have been reefing for over 20 years so I am at the point where the unique and unusual is what tickles my toes.
