For those not using a dosing pump, but otherwise automated dosing thingamajig...

[Delphinus]

In a futile attempt to reclaim my honour now (I realize that ship has sailed long ago, I may as well ask for my hair to grow back, but I digress), I'll add to this that I held off doing the Aqualifter pump dosing for the longest time because I was *certain* I would need timers that could do sub-minute intervals. In the end though that was a moot concern: in fact I'll probably switch the durations to two minutes per cycle because I'm having trouble keeping my Ca steady for some reason (just keeps dropping and dropping).
