Last friday mixed 5 bags of 46-0-0 uflexx (melted) granular and 3.3 quarts of aqua-cap in 200 gallons of water. Used half of it with no problem. Let tank sit for 2 days. Reagitated mix and turned off pump and melted another 2 1/2 bags of uflex melted and added the remaining aqua-cap. Sprayed fine till I got to last 30 gallons. Lost pressure and went to the shop. My strainer was all full of aqua-cap it looked like soft clay. Took out remaining liquid to find the tank bottom all clay. Took all afternoon to clean out. What happened??????? I"m almost to the point of stay away from this mix! Anyone else ever had this happen? How many of you guys have used this combo and never had any problem????
