well, i am going to start growing my own green water and hatching brine for my tank - as well as setting up rotifer, brine, and mysid shrimp cultures in preparation for baby cuttles (whether my current eggs hatch or not - i will be breeding them in the future).
i decided to start with the green water and brine shrimp hatching. i am going to run a total of 7 green water cultures - 2 liters each and i will have four tubes for hatching brine so i can have a continuous supply of baby brine as well.
here is how i am building them.....
it is best to use a cylinder that has a conical bottom to prevent dead spots in the bottom. i also wanted to have a drain in the bottom for dispensing and air injection.
first, i took flat 5"x5" clear acrylic and heated it in the oven to soften it up.
here it is before

here it is if you leave it in the oven too long :D

here it is being bent into the conical shape. i used a short piece of acrylic tube underneath to control the depth of the cone and another piece on top to preserve the flat ring for attachment while pushing down the center with 1/2" PVC (this is the size PVC i will use for the drain.

here are all 11 cones

next, i fabricated the inside bezel out of a coupling and glued it to a short piece of 1/2" pipe. notice, i have also refined the outside circular shape, cut the hole for the drain pipe and flattened both gluing surfaces using a belt sander

here is the drain assembly glued together

here is the finished tube - the wall mount is attached at the water fill level for 2 liters.

i will be assembling the other 10 in the next few days, updates along the way :)
