my alkalinity is very high yet my ph reads perfect is this okay or what do i have to do to correct this?

Not enough information to even begin.

Too high you say?
Is this too high just after you filled it up? Or did you add a bunch of stuff and then it went high? Or did it get this way over time, say a month or couple or?

What is your actual alkalinity ppm reading?

i` ve been using the tub for about 6 weeks and because it is at my cottage i only get to check the water on friday`s i1m using bromine for disinfectant the ph has been dropping every week so i add ph up and i get the ph perfect but now the alkalinity is sky high so can i use ph down to bring the alky down then ph up to raise the ph ?

yes

what kind of problems will high alkalinity cause? cause in another week i`m doing a water change, thanks swine

eat your pump seals (and everything else) if it continues long term.

Drain and refill the spa is always correct Rx when water gets out of control like this.
