Trying to dial in trident dosing even more

[Camaro Show Corals]

So I have been running my trident for about a month now and I do love it, even before it my tank was stable and wasn’t have any issues but seems that alk is getting just getting a little more swingy and would like to reduce that as much as possible and dial in my dosing as tight as possible. Here’s my current settings. What do I need to I don’t quite fully understand range and limit. By lowering range is the tighter it will stay correct? But won’t dose if it gets under or over?

 

[Righteous]

The range is simply the range between which the automatic dosing adjustments will be applied. Think of it like a safety range.. outside that range, your dosing will simply default back to whatever ml it was set to.

So actually with that range, the dosing adjustment will be almost nothing. Anytime the alkalinity goes above 10.75 or below 10.25 it will stop adjusting and need manually adjustment. That’s fine if you’ve already got your dosing dialed in and you don’t want it to adjust much. But if growth starts to pick up, and the alkalinity drops quickly below that range, the auto dosing adjustment might not pick up and push the dosing up.

So whats your recommendation for settings

 

[Righteous]

I’d recommend using the “Trident Controlled Dosing” task. On mine, it set the range to 1dkh and the limit to 35% for alkalinity. I’m not sure if that’s effected by the target dkh or not.

The task also has an option for dosing more during the day than night... which has made a huge improvement for me on alk swings during a 24 hour period.

I have found the same thing, although not terrible. I have been using trident controlled as Righteous said above.

 

[TheHarold]

Just need to make some adjustments

 

[Righteous]

Here’s mine with the auto adjustment trying to bring it up from 7.2 to 7.4... looks like it gets more conservative as it gets closer to target. My setting is range 1dkh, limit 35%

 

[Righteous]

I’m also running 12 tests a day at the moment. I figure more data will let it operate more accurately, and once I’m at target I’ll bring the testing schedule back down.

I am using trident controlled dosing, testing 6 times a day. I’m sure with more tests it would be tighter.

Im doing the minimum testing.

I asked the following question in the Aquarium Controllers forum, but got no response. Looks like there are some Trident-controlled dosing folks here that might be able to answer this.

How dose Trident handle controlled dosing in between readings and DOS has a change in dosing interval?

For example, I have my DOS dosing in three intervals corresponding to my photoperiod - midnight - 9:59 am, 10:00 am - 9:00 pm, 9:01 pm - 11:59 pm.

If I have the standard Trident testing schedule, reading alk at 6:00 am, 12:00 pm, 6:00 pm, and 12:00 am, if I get low alk at the 6:00 am reading, I understand that it will adjust the dosing. But is that just for the current dosing interval? What happens when my dosing interval changes at 10:00 am?

it always adjusts for the next test, within reason

 

[puffy127]

But does that include changing the dosing for the next dosing interval? Or only the current dosing interval? Or do you align your dosing intervals with your testing intervals?

 

[Billldg]

The more you test, the more controlled it is, if you test only 4 times daily then it only has 4 points to look at and adjust dosing as needed. I test 6 times and have found, for myself, that it keeps the parameter pretty close. Every once and a while it gets a little higher or lower, but it usually adjusts it back within a few test cycles. It doesn’t get so far out that I have to manually adjust though.

 

[puffy127]

Do you have multiple dosing intervals set in DOS and if so, do these align with the testing intervals?

Before the trident I had my dos dose over a 24 hour period. I have been thinking of having the trident dose more during the day.

I am using the controlled dosing, so it sets the intervals, it doses about every 12 to 14 minutes, it does ask if you want to dos more during the day or not, I choose to dos more during the day as I was noticing that my tank did in fact use more during the day. It has actually helped me raise my ph also, I dosed alk at night to keep my ph up only to find that it really didn’t help it that much, but during the day it actually keeps my ph higher for longer time thus it doesn’t drop as much at night.

I set my Trident to test 8 times per day, and over a week or so I adjusted my dosing schedule to fine-tune it based on the observed daily swings. This is what I'm currently dosing. I'm seeing about 0.05 - 0.10 dKH swings, so I'm pretty happy with it.

At the moment, I’m just using the Trident to dose ALK ober a 24 hour period, biased toward more daytime dosing. What happens when I set Ca do dose via Trident control? Will is space the doses apart as much as possible by default to avoid precipitation?
