I have 2 reef tanks with Apex and Tridents on both. Both are less than 90 days old. The Trident on the first tank stopped working after a week and had to be replaced. Now the Trident on the 2nd tank has stopped working--will not pull sample water--after less than 60 days in operation. I have gone through all the support steps and have a called scheduled with the manufacturer to troubleshoot. Is anyone else experiencing this kind of failure rate? I am in the processing of setting up a new custom-built reef tank and am leery about getting another Apex/Trident system.
