Welp, that's unfortunate luck for us then since every fish in our tank has a name. (Minus the anthias group, which is just called 'the polymerase gang').Looks nice n thick
fish with names tend to die first
i try not to name anything that doesn’t come when called
Yeah, wasn't fun at all. No idea how it happened since the screw that came loose was in a stud (I checked before, and re-checked afterwards). Cost us nearly every torch we had, including a nice malaysian gold.Wtf? Light in the tank, uggghhhhh
Mostly good; still frustrating.
I've been losing about ~0.25 dkh of alkalinity a day, so I decided now was as good a time as any to fire up the calcium reactor (an Aquamaxx cTech T3 reactor, using an FX-STP2 peristaltic pump to pull fluid through, and CO2 rate controlled by a CarbonDoser). Given the minimal demand, I'm opting to keep the pH towards the higher end of the spectrum (CO2 on at 6.8, off at 6.6) under the assumption the slightly elevated pH will result in a slower breakdown/leaching of alk/Ca/Mg from the media.
Starting off with a feed rate of 30 mL/minute; and so far so good, I think?

My only concern is that, even though I have the bubbles set on the slowest possible rate (1 bubble every 9-10 seconds), the pH drops extremely quickly; going from 6.8 to 6.6 in the span of ~20 minutes. My understanding is that the solenoid should be 'on' as much as possible, and the current setup means that it will undergo ~24 on/off events every day, or is this just not really a factor to worry about with electronic regulators?
Sorry; meant to respond to this.Have you adjusted the bubble size? I have the multiple older versions of the carbon doser regulator and it has the ability to adjust how much co2 is dropped (bubble size) per second.
Even though technically and a better implementation is having the exact rate of co2 dropped in without having to shut off the solenoid via pH probe, I’ve never bothered after years of using a co2 reactor and have never had crazy alk swings. I’ve managed everything through the pH probe and having trident to monitor and report the alk so I can see if anything is tending off course.
Welp, I am now four for four of my display tanks getting dinoflagellates at some point. This time is lucky number 'small cell amphidinium'.
Blackout for a few days, running carbon, running skimmer, and dosing microbacter to maximize biodiversity it is.
Sorry to hear about your struggles, and appreciate the input. Fortunately, this isn't my first rodeo with dinoflagellates and I'm 3 for 3 in beating them so far. Also fortunate that these are small cell which, unlike large cell amphidinium, go into the water column during blackouts and are susceptible to UV.Oh man, I just read through your thread (awesome build!) and the whole time was wondering about dinos popping up...I had the exact same experience with a dry rock setup, and the dinos defeated me. Sounds like you've done your research since you've identified the type. I spent many months in the trenches with amphidinium, and gave up battling them after several months and rebooted.
None of these worked for me, but people have had success with: adding lots of pods, many frequent blackouts over an extended period of time, dosing silicates to help diatoms outcompete, cranking up nutrients and waiting several months, increasing temp to 83 degrees, dosing H2o2 over an extended period, seeding with live rock...or some combination of the above. The most consistent themes with success seem to be biodiversity and time.
Anyway I'll be following along and wishing you luck! Really sweet setup, and very well thought out....other than the lack of live rock! I've become a huge convert after this recent experience.

My strategy in the past has been increasing nutrients (if phosphates are zero or low), adding bacteria/biodiversity, and adding UV. So far, UV has been the most important piece of the puzzle
