Just changed my schedule to do 2 tests in the middle of the day and skip the midnight test. This will help lessen my alk swing as my CaRx is controlled by the trident.
How do you do this? I want to check alk frequently but only when the lights are on. I could care less about b/c. If I could only test Alk that would be great.
I got some recently from us plastic. I got 1/8id 1/4od to replace my kamoer fx-stp tubing. Not sure if that would work for you. I only got 5 feet so, I don't really have any to spare but here is a link.

If you can find one of these used (they have been out of business for 3 years) it works very well. It is what I am using for an auto water change. https://reefs.com/product-review-genesis-reef-systems-renew-part-1/
