Alkalinity testing at 5DKH or 89.5ppm

[GoReefin]

Have a water volume of about 35 to 40 gallons split between a 20g sump a 13.5g fluval and a 16g rimless. Noticed my clam was no happy and checked my alkalinity with API test and it is reading stupid low after 2 tests. Any ideas what would be the best way to keep alkalinity stable in a smaller system long term? I could purchase a dosing pump but finding one that would dose 2ml of solution or less a day is proving difficult. I am curious to hear what everyone's solutions are.

My calcium is testing at 420

OP will need more than one pump later so Kamoer F4 I would recommend.

Awesome guys thanks so much! I was having trouble finding them under 1ml dosing.

You can daisy chain 4 x1 pro's and don't have to have an upfront cost of $380.00 for potential future needs.

You will want at least 2 one for ALK, one for Calcium. Manual dose mag. Or if your use All for Reef you would only need 1.

There are pumps that can dose very precisely. However the alternative is water down your alk/calc and dose more. I use a cheap jebao doser in my small tank and it works great other than I did have issues when only trying to dose very small amounts. So I water down my dosing containers with RODI and instead of dosing .5 ml at a time I dose 5ml at a time. Works fine. Would be an issue only if you water down so much that it impacts salinity (even then unless you have an ATO it should not matter unless you dont have enough evap to match what you dose).
