Randy...ALK help

[x2uranium]

I went to Aruba for 8 days.. I just got back yesterday.. I have my system on Auto top off Constantly roughly 2 gal per day, In aprox 65 gal total volume. My kalk is in a 20G container with 20Gal of ro x 20tsp of kalk. I leave with my dkh at 9.2ish I get back my dkh = 6.7 (Converting using Lamotte test kits) I thought that the kalk would maintain the alk for 1 week. Or am I just using too up too much alk that the kalk cant replace it. I am using your 2-part to dose for water changes to bump up levels ( Coral Pro )

Am I going to have to just start a dosing regimine daily??? Along with kalk in the topoff???

I noticed this because 1 of my frags that I have had in my system with I got back had alk burnt tips tested and it was very low.

With a lot of SPS, limewater alone may not be adequate. Assuming you correctly mean teaspoon for tsp, then your limewater is also a bit weaker than it could be, and you could try 2 tsp per gallon of fresh water if you continue with it.
