Trident! Who wants one?

I'm on the NSI team but wasn't selected for this one :(. When the 2nd round of units went out recently I was inadvertently given access to the private forum. I did some reading before I notified Russ and was removed. I'm not going to divulge any real info but I will say that the testing was going rather well with no big issues. It was a pretty big let down when I found out I wasn't gonna be a part of that 2nd round.

For those keeping SPS this will be a big step towards a very high level of stability. The cost really isn't bad for what you're getting compared to the other options available. The pricing was said to be under $600, to me that probably means $595. Replacement reagents are $45 and they last two months, so $22.50 a month. To be able to see how the system uses the big three and knowing exactly when to dose or how to really fine tune a carx is going to be huge. Also to see a problem occurring and be able to correct it before it effects the corals can save you well more that the cost to buy and run the unit. I also hate testing, too only have to watch NO3 and PO4 is going to make my life a lot easier, I can't wait!!!

Oh, and combined with the DOS and/or a carx it will be able to make adjustments to the amount dosed or the pH of the reactor on the fly. I believe +/- 15% of the original set points is the limit. That maybe modified prior to the official release though. That info was mentioned in their biweekly videos.

Good to know they have designed in guard rails, in the control loop.
I would be very wary in any case before using it for 'dosing control', but this feature is somewhat reassuring.
Why couldn't we control any dosing pump?
Does it REALLY have to be their DOS?

You could probably control another brand dosing pump through coding. But I'd think it would be quite a complex set codes. With the DOS, the system knows the exact fractional ml that it doses. With another brand that doesn't have that level of resolution it would become a time to run setting based on the static amount dosed over a given period of time. Then you'd have to figure out how to adjust the timing to alter the dose for scaling within the +/- 15%. Not sure all of that is possible. I don't know of another doser that is Apex compatible which could offer down to the tenth of a ml resolution.

I will say that I will be monitoring it for some time before I hand over any dosing or pH control. Even then I think I'd want the limits tighter to start.
There are still multiple other safeguards that can be implemented as well. Within the output you can shut down it's function if things get out of line, with alerts sent simultaneously. pH too high or low, Alk getting too high are just a couple of those. I think part of the reason it's taking so long is this aspect, I believe.

I will have to repost my hack for pumps.

I guess I will be getting 3 in but not 100% sure. Might be more or might be less. More is better of course. 2 were prepaid and the rest are on the waiting list but not paid. Just letting you know, folks that paid upfront get it first. Only fair to them.
