Just talked to Max again and ordered my FH. We will receive 1300 Friday. I told him the results of my water test and how I was concern about the low alkalinity. He suggested I try one box to see how they would do. I agree Max is a helpful, friendly person. I was a bit taken aback about all the info he gave me. My husband liked the idea about the black bug light. We use to have two lights on our pier but decided to tear the pier down because it was rotten in places so we do have a source of electricity. Can anyone tell me more about the black light bug light?
