What should i do???
 

I am going to be going back home for christmas and my tank will be unattended for about a week. I have a top off unit and an auto feeder for the fish but im worried about dosing. My few lps and sofies should be fine but i have 6 sps frags that are really starting to grow and im worried about my alkaline i have to dose about 10-15ml a day to keep it around 9 kh could i potentially run into major problems????

perhaps add the alk supplement into your autotop off water? or else finding a tank sitter is another option.

Get an auto-doser or a tank sitter. An automatic doser is the better long-term solution.

I would use Kalk water for the auto topoff in your case. it will supplement alk/cal at same time.

I would also Recommend Kalk as a top off, and I would post in tyhe Edmonton for some one to watch your tank.. lots of people there to watch it.

I have a (professional) tank sitter looking after my tank while I'm gone.

i talked to Aquarium Illusions and they recommended adding the alk to my auto top off so i think i will try that route....
