Yes don't be afraid of DIY maintenance. Many tips on line,We have a large in-ground one. Opened in April 11, just in time for weather to suck again.
I was in it at midnight last night after work. Found a FB group for DIY pool maintenance that is very helpful.
Get a good test kit with actual chemicals, not Dip Sticks. I am paying someone for pool maintenance now but may go my own way soon as market tanks.
and yes as Doc said use a good test kit and chemicals.
