I've always shied away from test strips for aquaria because of problems
I had with pH papers when I was working in laboratories. When I
compared pH test strip readings to pH meter readings, the test strip was
less reliable and would give different readings depending on how I
dipped it.

I was looking at the Mardel 5 in 1 test strips and they test for the all
water parameters I need for a good price. Has anyone compared the
readings on Mardel strips to tried-and-true tests like Seachem or Hagen?
I'll be testing FW but am interested in anybody's observations. Are
the strips easy to read, accurate, and do they give the same reading on
repeated use?

TIA,
Elaine
