Hi,
Last December, I built a wood-fired hot tub from an old steel tank. During the process, I ended up welding some new, rust-free metal inside for brackets, etc. I also wire brushed the inside down to bare metal in places. I didn't take into account just how much the new rust would affect the clarity of the water. After only 2 weeks, the water was so rusty that visibility was down to just ~4" or so.
It's the new rust creating the problem. I believe that after changing the water a few times, I will have less of an issue... after the rust seasons, for a lack of better way of describing it. However, short of hauling fresh water in, in the back of my 4x4 truck, my only water source is from a rainwater/snowmelt harvester... and the tub takes up a significant portion of what I'm currently able to harvest.
I'm hoping to find an inexpensive way of filtering out this rust, on a trip by trip basis. In other words, given the tubs remote location (no electricity), and the fact I do not live there, I'd like to figure out a way that I could remove a good portion of the rust in a short amount of time (~1 hr). My water doesn't have to be crystal clear. I would like a good improvement though. :-)
I have a generator and a 3/4 or 1 horsepower water pump. Could I somehow rig up a filtering system with those two things? I suppose I could rig up some sort of solar system... but, for the sake of saving some money, I'd prefer to work with what I have... if there was a way.
Anyone have some ideas?
Thanks,
FN
