SPA50 Posted April 30, 2014 Report Share Posted April 30, 2014 Hey guys I'm looking at getting a TDS meter to check my hardness for my shrimp. Has anyone got a cheap tester that's not too bad. Looked on eBay and found ones for as low as $8. But was keen on one from Aus for something like $13. Before I buy one has anyone got a recommendation? I'm not going to be spending over $50 on a tester as I'm only needing the basics and prefer not to use test kits. I suck at those. Cheers Link to comment Share on other sites More sharing options...
beencees Posted May 1, 2014 Report Share Posted May 1, 2014 I bought one for $10 (blue one) from ebay and then compared readings on multiple tanks with my mates you beaut $160 one. Every reading was within 5ppm of each other so i would say go for an ebay jobbie. Link to comment Share on other sites More sharing options...
