<p>I've never had problem with Xtol. Except for once in the clubs darkroom. The water was not hot enough and part A didn't dissolve properly. And it MUST be completely dissolved before adding Part B. I tapped a lot of hot water in the sink and put the tank in it to warm up, shaking it several times until it was completely dissolved. Then added Part B and put it back in the sink until finished. Use rather hotter water for Part A. If you are going to use it immediately you can add the last litre with very cold water.</p>
