pH meter or combo ph/ppm meter
pH up & down
1938 Rolls Royce Silver Cloud with 3 hookers inside $475,000.00

Wally world (Wal-mart) has compact florous cheap. They are compact and can plug into a regular fixture. Prices vary from area to area. The ones I got were 10 bucks. but GG stated in another post he could get them cheaper.
