I use a syringe to add the ALK slowly into current otherwise it really upsets my sps. You can just dump the CA in.
I suppose you could drip it like kalk, but I get good results with two doses.
I would go automated with a dosing system, but I dont like to trust anything that can crash my tank like ALK component to a device. Probably why I dont have an auto top off either. I have heard too many stories at the shop of people crashing tanks because of broken ATO's or dosing pumps. I dont play that.
Well, I have been working a lot and not doing much with the tank other than maintenance.......I also had a major aiptasia problem! I got some aiptasia-x and so far so good, seems to work better than kalk or joes, but only time will tell!

I got rid of the flower anemone and made some more room for zoanthids, I still have a few types I need like tubs blues and PPE's before my collection is complete....If that ever happens lol.
