So I've been out of the hobby since 2015. Had to break down my build and get out because I had kids and figured there would be no way I'd have the time for it any more. Told myself that one day when tanks can be more automated, I may get back in. So every now and then, I check back on this forum to see if there are any advances. From what I see now, it looks like there are kits that can automatically test for multiple parameters and actually dose accordingly. Has anyone tried the triton kit or the Mindstream units? I've been itching really bad to get back in and if these units work good, it might be my chance.
