Is anyone with a mindstream or seneye ammonia reader willing to co-fund a cycling experiment with me

[brandon429]

Jedi thank you for those contributions that’s so on point for our thread here for sure

I didn’t know there were other seneye-seers out there lol that’s neat to see many confirmations of bottle bac efficacy

Day three ammonia is reading 0.001

Day 6 update ammonia has been stable at 0.007 for two days. pH is kind of low 7.6. Fish is acting fine, water looks clear and smells fresh. Is it time for a large water change and soft corals?

 

[brandon429]

I’d add some without a wc, the ammonia is ok here and there won’t be much nitrate either, gtg

Tank is 20 gallons, 5ml of OceanMagik phytoplankton. Nothing in the tank to consume the phytoplankton. I thought it was live phytoplankton and would start the food web.

I apologize for the extremely long delay. I have been swamped with work and while the two tanks are next to me all day... going into the garage to get the Phyto was another thing.

So, I dosed 6.5ml of Tommys' Phytoplankton (sold on this site) into the tank and the recommendation is 15ml per 50 gallons. Keep in mind this is a ~3G tank.

I monitored the numbers for an hour and no real increase. The Seneye in the tank floats up and down frequently by 1 and then generally stays at 0.50-0.60.

So far things are looking pretty good. Sorry for the blue pictures these are my old lights and I can’t adjust them.

This is interesting, I have a senseye but never bought another slide for it as I use only for PAR meter, however I dose ammonia for my clams. Would be interesting to see the results, perhaps I should pick up a new slide.

@Jon Malkerson

we do need another step Jon truly. We need to chart nh3 rebound rates in a tank to help a stuck cycle poster. Can you pls remove any fish if possible just for a sec, I expect no inverts will be harmed, and dose the system up to a tiny hundredths rise in nh3

then seneye shows us how fast it goes down, add fish back in an hour is the hope. This thread is now approaching six or so tenets in microbiology that are not well established in reef tank science, authors can take note of the data for sure as it unfolds. You’re dealing with a seneye that has been 100% contextually verified in extreme settings plus you understand how tuning the machine works, that’s a rare combo. We don’t get much actual digital insight from this perspective.


your tank is best for this inspection because everyone else’s tank is a full on reef


yours barely out of the gate. If it moves ammonia, then they’re way past control but can’t measure it correctly.

 

[brandon429]

Also
You're already practiced at adding nh3 into running systems, if you want to test it with fish that's no different, no reason to remove them per the ammonia dosing thread.

you'll be adding already known safe amounts on a precision tester, it's not haphazard

 

[CoralClasher]

Ever since I added corals ammonia has been stable 0.002 even with phytoplankton dose. I’ll dose a little ammonia and report back.

Your updated measures are telling this clue in my opinion:

we dislike .001 readings on seneye as calibration alerts but yours being one step above it, sustained, in a known very bare system, seems to state .001 can be right or meaning levels truly under the detection limit on some tanks. eg super mega low nh3 levels

I’m still learning this Seneye and this is only my third slide. I just noticed this slide is more sensitive now it’s 8 days old. The first slide in DT acted the same. In my DT it would always read 0.001 so trimmed it to 0.005.

I could not "break" mine out of .001 until I dropped it into a bucket of tank water, added drops of ammonia to spike it to 2ppm, and then placed it back in the tank I was monitoring.

By the way, this was the guidance that I was provided by Seneye support.

 

[brandon429]

Thank you very much for that input, ways to tune. inside ways that’s excellent.

Ok I’m getting some misreads. I dosed .3ml right on above the unit jumped immediately to 0.059 then dropped to 0.009 for an hour. I thought it should of dropped more so I cleaned the unit and put it back, got a reading of 0.024. The next time I dose it will be on the other side of the tank.

 

[brandon429]

It’s handy to see however it manifests, very fine detail to pick up- where the initial dose dilutes into the tank counts bigtime. would have not thought of that

 

[CoralClasher]

I’m really bad at math what should ammonia be at .3ml in 20 gallons? Directions say 1ml in 20 gallons is 2ppm.

Calculator

That's my only way to know / plug in % solution plus volume

am checking it sec

 

[brandon429]

What is the % ammonia contained does it say
