Hello everyone. I have a brand new Strong hot tub, and have many questions. The tub has a capacity of 354galloons. I wanted to know if you are suppose to treat a new hot tub different than that of a properly maintained used one? Like do you need to fill it and then shock, and then drain and refill?
This is what I did on the tub. I filled the tub from a garden hose after after waiting 2 minutes for any bio film from the hose to
wash out. I then checked the chemicals.
PH=8.0(not sure the actually number)
I then added the Leisure time perfect spa balance. I waited 30 minutes and retested.
I actually did not test anything else.
I then went ahead and added sodium bromide and waited 15minutes before I added the Leisure time renew. After I added the renew though, the water became slightly cloudy. Would introducing the renew so soon cause this issue? Also the temperature of the water was at 66 degrees. I do realize that the CH is on the low side. The TA could be at 150ppm.
I also have a instruction booklet from Spaklear which states I should adjust the calcium to 200ppm before I try to adjust anything else, is that the correct procedure? I always thought you adjust TA, PH, and then CH.
And lastly, when dealing with hot tubs, should you allow the temp to reach normal operating temps before adjusting anything at all?
Ok, here is my last question. I tested the water on a pool today, and the ph was 8.0. I then introduced 1gallon of 12% liquid chlorine. I retested 3 hours later and the FC=0 and PH=7.0???? Why did the PH drop? I am using a taylor kit btw. I then tried diluting the pool water sample with hose water to retest the ph. It was 8.0. The pool did have some spots of green algae present.
