Not good enough

REVIEW
I wanted to like this test, but unfortunately it just isn't good enough. Using the plastic dropper to get the right amount of water to test is easy enough, but I found it wasn't very accurate with the small amount of water as sometimes a drop or two would stay inside the dropper and never make it in...Read More

REVIEW
The pH and Alkalinity kit is very easy to use and fairly accurate.My only gripe, along with others with similar comments, is that the multi-cavity plate is very light and could be unstable if one is not careful.

Kit seems to be accurate but kind of difficult to use. The tray sample its placed in is thin light plastic and extreme care has to be taken when mixing not to dump the sample inadvertently. Also the drop dispenser can get air in it while your dispensing and release an "splatter" of reagent...Read More

I also have the tetra alk test kit and would recommend it over this one. I think has a great test vial (it's square and d...Read More

REVIEW
For the product, I have used it for years and I have found it always to be accurate as all of the MultiTest kits I use. When received I was not shipped the correct kit. However, customer service fixed the problem and shipped me the correct kit that I ordered. Prices are very comparable to the on-...Read More

REVIEW
The kit worked very well. I ordered when getting unusually high alkalinity numbers with my Salifert kit. I ordered this one, plus the LaMotte kit and compared all three on the same sample. The results were identical. The lower cost of the Seachem kit, and the added pH test included will make me ...Read More
