Auto doser.... SPS now dying

[MarkoD]

Doesn't the doser allow you to adjust volume in mL?

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.

I have a 72g mixed reef and have my doser adding 2 part, alternating every hour at speed 4 for 12 seconds. So it would dose part A at 12pm for 12 secs at speed 4 and then dose part B at 1pm at speed 4 for 12 secs and so on 24hrs a day.

Your system seems similar to yours.

So you dose both 12 times each/day?

Pat please give us details on your system and dosing frequencies and times, can probably figure it out for ya, dont forget to post your times of day for dosing each

Unless they doser failed, I dont see how this is the dosers fault?

I agree 100%. Can you share the details of what you are dosing? For example I dosed Dowflakes for years but then got a very impure batch & had nothing but trouble, this product is only about 40% calcium chloride on a good day and can nuke a system. I will never use it again and don't recommend it & feel it had a lot to do with my tank crash in 2010/2011. The calcium chloride from BRS, Fauna Marin or Eli in Calgary is all very good purity wise. Not sure if this relevant in your case but I thought I'd throw it out there. Long story short, it's unlikely the problem is the actual doser but more likely what you are dosing and in what quantities.

Yes, just alternating hours.
