Thanks all, still have loads to come.....
Also I need to redo a few things where I feel I made mistakes.
Sure I am going to be asking for loads of advice soon as well.
My auto top is crazy at the moment, I am loosing about 20 liters to evaporation a day, so i need to fill a drum up, carry it inside and fill my top up reservoir each day. This is major works and a pain, I need to figure out how I am going do this part better. Some form of plumbing solution will be needed.
Maybe pick up a water line in the roof, fit the RO DI unit up there and run the outlet down the wall in a old electrical conduit to the sump. then run the outlet to the geyser overflow. I will need to fit a solenoid and powered float switch to run the solenoid in the roof. This is going to be a huge head ache!
Also I am creating a whole new problem for myself and deviating from one of my core ideas. I only wanted to dose one thing on this thank, Kalk nothing else. This done with my ALO in my RO tank, if i do this that method will be out the window and I will need to go the whole carx CO2 reactor and cylinder route. Luckily I do own a Tunze CO2 calcium setup but was hoping to stay away from this method and stick to kalk.
Anyways, I need to get this one sorted soon.... its a real pain in my behind!
