Unfortunately the pickle jar has been retired this week.
The hole in the lid for airline tubing was rusting due to the water bubbling up from the sponge filter. Should have sealed it with silicone or clear nail
LED lights failed this week due to humidity and getting into the casing - from the same "water from the bubbler" effect.
I think next time I would have used a smaller sponge filter. The one I was using was for a 20 gallon so the uptake tube was really high - splashing water on the lid and LED lights. I think the little ones only have two inches or so of uptake tube.
But the tank was good enough to breed CRS, I got one batch of babies from it and two berried ones right now just about to pop. However all almost all of my tiger shrimp in there died, possibly from the warm water from the light being on all the time.
