Yes they are. The initial cost plus the cost of the reagents far out weigh the inaccuracies of other test systems.

Sorry, did not check the date.

I had a huge outbreak after the tank crashed because of the snowstorms last season. I used Microbe-Lift Special Blend and shortened my photo period to 6 hours and had the Cyano licked in a couple of weeks.

Check with The Marine Scene in Herndon. http://marinescene.com/ They carry them on occassion and will special order.

This is a slightly different tact...Depending on the size of the measuring cup (1/2 cup) becase they do differ from style and manufacturer, does any one know how much a true /2 cup of Instant Ocean Sea Salt weighs. I have used a variety of 1/2 cup measures and have accurately measured the water (by weight) but come up with a different salinity each time.

I am so sorry for your loss.
