We switched to Colitag from Colilert due to the Price we received from distributor and also due to the 16 hour test capability. Problem is with the very slight yellow color change that determines coliform presence. Almost all samples seem to turn to this slight yellow upon inserting Colitag. We are now switching to Colisure.
Pros: 16 hr test capability
Cons: Too slight of a color change ...
Would recommend: No
