I am trying to decide which is better for my tank- I often leave my tanks in the care of non-fish people, and I think this would be a good thing for them to check just in case.
The Mardel monitors were my first choice but require replacement cartridges monthly.
The Seachem monitors last for a year and end up a little less expensive, but when I searched on here it looks like some may have had some problems.
Anybody cast their vote one way or another? Thanks!
