Every time my Kamoer dosed Alk my tank was turning into a snow globe . It all cleared up in 20 sec , but it was annoying, and i was worried about a clump landing on polyps and causing problems . I cut an air hose nipple off a one way valve . Then got a matching drill bit . I drilled the loc line on my return , and super glued the nipple into the hole . Then hooked the Alk line to the nipple . I have a random flow head on the return . Now when she doses Alk , it is totally clear . I hope this helps someone . Ned
