Auto doser.... SPS now dying

This one uses time setting and Approx dose volume. The theory is that when the pump ages and tube wears, the volume setting becomes useless and setting based on lengthening or shortening the cycle is more accurate.

It could be related to the chemicals being added to the tank? When I switched from my 2-part to the calcium reactor I had some swings in PH, ALK, Ca and MG. All of which I just dumped "estimated" amounts of each chemical to "balance" it out, nothing died in that process.

On another note, my refract went crazy on me and I ended up bringing my salinity upwards of 1.030+ then dropped it to 1.026 within a single day. Nothing died.

By no means is my method "right" in any way, so for anyone reading this... don't do this because I got away with it. But from my experience, these corals are fairly durable if your parameters swing within reason.

Alk start at 2000-30s- speed 2
2300-1:30- speed 2
0200-2:00- speed 2
0400-2:00- speed 2

Calcium I start at 0800 and basically the same schedule.

I test every couple weeks, and adjust accordingly.
