What do you Dream about?

Gravity Fed Fluidized Bed

I made this fluidized bed filter out of some polycarbonate scraps. It has large grain sandblasting sand so the bubbles from the gravity fed water doesn't eject the sand into the sump. Holds about two gallons of sand. It is not fully fluidizing at this point but all the sand is moving. The holes are left over from the sides being aquarium lids. Most of the water flows out the sides that form the angled sides. I'm working out the kinks of an air purge system to so I can put finer media with more surface area.

Tank Plumbing

In my fishroom all tanks have at least one bulkhead. Lager tanks have two out the back. The holes a 1 3/4 inches for a one inch bulkhead. The hole is drilled 6 inches in from each end and 4 inches down from the top.
One bulkhead is plumbed to drain so it can be used to empty the tank by rotating the pipe down or as the primary drain if run on a flow through configuration. To make this work as a drain that can siphon the tank empty the plumbing needs to be vent free to below the tank. Just think of it as a siphon tube running through the wall of the tank. If you vent at the bulkhead you can run the intake on the bottom without emptying the tank. Generally I plumb the first way and if I want bottom suction I simply put a tee at the inside of the bulkhead instead of an elbow.
The other bulkhead is plumbed to a central filtration system in a surface skimming configuration. Water is supplied to the tanks via a plumbing manifold with a supply valve at each tank. Water can be from the recirculating system or through a hose for large water exchanges. All tanks have box or sponge filters.

Ranchu mold mark on a Gatorade lid

Soon after the Ranchu bug bit me I found this on a Gatorade bottle. I
thought I was crazy seeing Ranchu every where. Just found it in my
desk and thought I'd post a picture.

180 Gallon Truvu

Swapped out 6x 29 gallon tanks for a 180. It's plumbed to drain and to the main goldfish system.

Here's what it looked like when it was installed originally.

Resealing my first 6 foot tank for the 3rd time


I first saw this tank at the cichlid hobbyist's house who sold me my first african cichlids when I was 14. The tank had a colony of brundy frontosa. We caught a dozen fry from the tank and I was on my way. After high school he took up gold mining so I bought the tank and put my frontosa in it. It's been in every one of my fishrooms.This is the third time I've resealed it. It is a 1979 all glass 100 gallon (72x18x18) with 5/8 inch glass. It is plumbed to the central goldfish system through a 1" bulkhead and to drain with a second bulkhead. It has a very primitive frame, well trim actually so I'm going to put in eurobracing around the top so I can put better lids on it.
Here is one of the hockey pucks from the bulkhead holes. A great tank resealing article.

The Original Clear Zebrafish: Beyond Blingless

This line is called “Beyond Blingless” and was developed by Znomics Inc. a now defunct biotech company in Portland, Oregon.  It’s was a clear line but it utilized Albino^b4 which is a deletion line that is very weak in comparison to Nacre alleles making it difficult to produce.
