Well.... at this point you have no real direction to go with other than best guesses. Go with your gut till you can get a decent PH pen.... You're prob gonna need to spend more than $100. The Apera was almost $500.00 , but it's super accurate down to the 100th of a point.Not at a the moment. In a couple of weeks, I can make it happen.
