The Shrimporium is not unlike an advanced game of Whack-A-Mole. The moles would be: equipment issues, power issues, water chemistry issues, fauna and flora husbandry issues, maintenance issues, streamlining issues, emergency planning issues, etc. Oh, yeah, and this mole: recordkeeping issues - HEY I NEED A SHRIMPTERN 3.0 WHO CAN HELP ME WITH THIS PROJECT ALONG WITH OTHER COO-EL PROJECTS LIKE THE DIY SPECTROPHOTOMETER AND THE DK WATER SNAKE - CAN BE THIS SUMMER OR THIS SPRING BREAK IF YOU ARE A STUDENT TYPE. WE FEED AND HOUSE YOU WELL BUT WORK YOU HARD DOING CRAY-ZEE WEIRD SHRIMPORIUM DOINGS.
Right now, DK is grappling with an unusually high failure rate of a heater she started to transition over to. Thankfully, she didn't fully transition (she buys heaters as she has shrimp cash).
Here is the product. DK's experience is that this product has a much too high failure rate. About half of the units she's installed have already failed. So, she warns you. The picture below is the type DK actually has, the newer model is in the link below.
Via Aqua titanium heater
. She has an older styling than this picture, and they may have fixed the problem, but her problems are that the control unit stops controlling, the indicator light doesn't light, and no heat is produced. It seems more like a controller issue than the heater element failing, but there's no way to determine this easily. At any rate, they DON'T work after about a year! And to be clear, during the WFIII cycles, the heaters kick on toward the end, and only run a minute or two. They hardly run at all in between cycles as the tanks are fairly insulated. I am not overtaxing the heaters!
The above mini-rant started because DK was preparing to post of a bird's eye view of Shrimporium progress, to date, because she has moved past some significant milestones in her global goal list.
Namely, at present, from a single water source
(her carbonated well), she in the dead of winter now has Water Factory systems running to produce on the fly
different waters that are successfully resulting in berried shrimp right now in the following tanks. There are three aspects to this that were part of the global goals that she has made significant progress on that she is sorta celebrating.
- Waters for basically three different types of habitats from a SINGLE water source, made on the fly.
- Water recipes made from cheap, easily available ingredients - almost nothing proprietary (the one exception is the fertilizer branch with includes CSM + B, potassium nitrate, and potassium phosphate ordered online).
Everything else is cheap and DK can get within 5 minutes of where she lives either from a big box BORG type store or a grocery store.
- Using the first two, she can get AT THE SAME TIME, rather different species into breeding mode.
She spent a couple of years trying out things and could get the neos to fly but the caridina weren't happy, or vise versa, etc., and this has taken quite a bit of problem solving. This in itself is not that difficult; the DIFFICULT part of it is she INSISTED on making a global water system with cheap, easily available feed vats (the injection concentrates from which she makes the various waters) that are fairly simple.
Right now, the entire system runs off 5 feed vats, and she's in process of transitioning this to four if her latest trial is successful. She makes feed vat concentrates once every few months, and it takes a few minutes a batch plus she stirs them overnight.
So when all is said and done, she is pretty darned lazy - no water changes, and only make 5 recipes of shrimp juice concentrate every few months. Not bad.
Now, granted, the berried number in most of these is very low as it's dead season not breeding season. DK was wondering why her berried rate isn't higher in her Blue Tigers, and this led her to start looking more at tank temps, which she has dialed way down. But on top of that, this morning she noticed that one of the Blue Tiger tanks is downright cold, and a quick check of above-mentioned heater in said tank resulted in learning that heater is kaput.
Last winter, she ran up against some barriers, namely that when the Water Factory kicked on while all the tanks were lit for the day, all the heaters would kick on during the cycle as cooler water entered the tanks. The combination of all the lights AND all the heaters running at once caused her circuit breaker to pop each cycle on colder days when the incoming water was colder. She has all her tanks on one circuit which is run into the emergency generator panel, this is why the breaker is not diversified.
So, as those of you who are faithful readers recall, last winter she took step one to ameliorate this: she built a heat exchanger
for incoming tap water entering the WFIII.
Next, she shortened the WFIII cycle times
, so less cooler water enters the tanks each cycle. This is a finely balanced thing, as the TIME of cycle affects a number of things: fraction of water turned over and therefore amount of water freshening, temperature dip experienced by tanks during cycle, relative fraction of carbon dioxide entering tanks each cycle, how much time heaters kick on and when due to cycle happening, etc.
Third, she dialed back winter tank temps, down near 70 (except for the Sulawesi bank of tanks). But this year, she wants to raise those temps back up toward 74, as the lower temps are depressing breeding.
So, she is doing a lot of prep toward power balancing the cycles.
This post is long enough, now. More on that later.
And one of these days, she'll continue the CJDS posts.
