CRASH!!!!!!!.
No, not my reef, don't be ridiculous, I have a reverse undergravel filter and everyone who has a reverse undergravel in their tank that crashed, raise your hand.....Higher.
My worm culture crashed. It didn't crash because the worms died, it crashed because I have to many worms. And flies. My two worm cultures are inundated with flies. The fly larvae looks just like worms but a little shorter and the flies are really annoying. They fly around and crash into my bald head.
I tried many things to rid the thing of flies including completely flooding the culture overnight and leaving it outside when it is 35 degrees. The flies just laugh at my feeble attempts and their squeeky laughing really grates on me and exasperates my already grated PTSD.
I also built a container with a small fan on top where it would collect the flies as they hatched and sucked them into a net.
So today I left them outside where it is 30 degrees to stop them from laughing then I quickly flooded their container while holding a huge shop vac over it and as each fly warmed up and climbed out, I sucked them up.
I don't have one of those Sissy Girly shop vac's, this one I built and it will suck the ear wax out of your ears from 10' away through 5/8" sheetrock.
Then I kept running water into the container and pouring it out until it was clean with not a trace of worm or fly poop. After that I poured the entire thing through a course net and ran water over it for 15 minutes which removed most of the soil and those pesky gnats or whatever those little bugs are.
The next step was to swirl what was left, a little at a time in a round container. That congregates the remaining worms in the center and now they feel like they just went to midnight mass and drank to much wine. I sucked up masses of them with a baster thing that I built and put them in a clean container.
I collected about a pint of pure worms. I am sure some of those fly larvae got in but I can't be sure.
I threw out thousands of worms but I still have another culture that has even more flies in it. They are outside now where they may freeze. I will show them.
I may rescue those worms but I have so many that I really don't have to.
I am also considering a new way to collect the worms. I am going to try to use vermiculite which is really tiny pieces of Styrofoam instead of soil. To collect the worms I will just flood it and the vermiculite floats while the worms sink so I can suck them up with a baster. I am not sure how the worms will fare in vermiculite but the next time I go to a garden center, I will get some.
By the way. I don't consider this a problem, a catastrophe, an annoyance, an inconvenience, a set back, or a disaster. It is a part of my hobby that I love. Opening up a can of dry food just doesn't do it for me nor does stamp collecting.
If this was easy, everyone would do it even Nancy Pelosi and she doesn't have a tank.
