this is the main mixing valve bank to make ro/di water into salt water. everythig is controlled from this set of valves and is pumped up to one or both of the tanks on the stand. then it can be transfered to the sump or the skimmer for the water change.
this is the control box that will run the 2 tidal surge tanks. it has 4 simple items in it. 2 delayed break relay switches and 2 electri solinoid valves. the relay is activated by a float switch mounted into the surge tank.
more pictures and maybe a video or 2 tomorrow.
