In looking, all of my reef test kits have expired and need replaced. I honestly haven't used the test's much in the past, but as my reef experience expands, it seems more and more necessary to be able to test water at home. I have only 28 gallons, but a mixed reef with a fairly heavy bio-load.
Could someone (or someones) advise me on a good brand for the money and where to buy? I'm on a budget, but don't want to get sub-par equipment.
