#ed_op#DIV#ed_cl#I am in the planning stages of building a custom tank. This is what I am thinking, let me know your thoughts and ideas. 4' Long, 4' Wide and 18" deep. So it would be essentially a large square. (I have forgoten the formula for calculating the gallons of this. Does anyone have it?) I would light it with Metal Halide Pedants. Any suggestions with wattage, color and number of Halides? I want this tank to be able to handle SPS, Clams and anything else. I am going to build out of Plexiglass. I know it is a soft material that scratches easily, but you will mostly be viewing this tank from above. Any suggestions on filtration? I have been out of reefing for about 3 years and I am not up to date on some of the latest equipment. I have never used auto dosing or Ozone or electronic probes, but this set up would perhaps warrant that. I like the idea of a large bottom areaand a fairly shallow tank. This should be much easier to maintain than a traditional deep, narrow, long tank. I am thinking a refuge below the tank with a mini mangrove forest growing. I live near the water hear in South West Florida and Mangrove seeds are easy to come by. That last time I did a mangove refuge I had pods coming out of my ears and the water quality was super stable. I lit that 24 hours, but I may just set this on opposite the tank. (Your thoughts?). I need suggestions for a skimmer. I like tons of flow at least at selected times of day. I may set at least one very high volume pump to come on for 12 hours at night just to stir things up and leave it off during the day so that you have a nice smooth surface to look down upon during the day.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#Thanks,#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl#
