Simple dosing info request

[NE reefer]

Hi everyone

I’ve got a 90 gallon display tank with a diy 75 gallon tank as a sump. Tanks has evolved over the years from a 20 gallon system to the current tank. Very simple system. I only currently dose kalkwasser via ATO. I’ve got a mixed reef, no acros.

I’m looking into dosing AFR to slightly boost ALK and trace elements. Any recommendations for a dosing pump that will add small volumes on a timer or a really slow continuous drip

I use this unit, I like how simple it is to use with no apps required. It's great for the price, and has 4 dosing heads in case you ever want to expand your dosing regimen. https://amzn.to/4rahM42
