Best Apex Trident Knockoff???

[Louiemiller9]

Looking for a cheaper alternative for the apex trident

 

[Philly Reefer]

There is no such thing as cheaper alternative if you already have an apex.

If you don't have an apex, alkatronic

For automatic testing the cheaper alternative is to hire your neighbor. Other than that there is none unfortunately. If manually testing Salifert and Hanna test kits are the way to go.
