I have a 32 gallon fluval flex tank (ie it has a tight fitting hood) without a sump and some Apex equipment (an ATO and DOS). I’m looking to add A/B or kalkwasser for the first time. I’ve got some noob questions I was hoping to get advice on:
- What are the pros/cons of A/B vs kalk for an LPS tank?
- How would you add kalk in an ATO or in a DOS/DDR? I assume I would mix kalk separately, let it settle for a day, and add the non-slurry clear top part to the ATO after it sits for a day. Does this sound right and how much kalk to ATO water is a good ratio? I have a lid and little evaporation (a few cups a day).
- Would you recommend using a DOS and DDR for adding kalk instead of an ATO reservoir? I worry about optical sensors in DDR with kalk or any other damage kalk may do to the DOS.
- How long can kalk be mixed ahead of time and put into a container with a lid before its no longer good?
