1. Teflon Tape Winder -
The wheel on which the tape is wound was cut to make 2 plastic disks. The inside diameter of the 2 disks was increased by cutting it with scissor.
2. Aluminum wire mesh was cut in round shape to match the size of the 2 disks (2 pieces of alumimum wire mesh disk) connected the electrical wire with the help of soldering rold. Two ends of wire to 2 pieces of wiremesh.
3. Now the challegne was to avoid the contact between the 2 wire mesh disks, so found out as old tennis racket (plastic) of my kids and cut the inside plastic squares so as to wor as a seperator beteen the 2 wire mesh disks.
4. The outer ring of the Teflon Tape Plastic was used to fix the parts as under -
a. made a whole in the out ring to insert the electric wire
b. bottom layer plastic disc
c. on top of it wiremesh disk
d. plastic squares cut from the racket on top of wire mesh
e. 2nd piece of wire mesh
f. covered it with the 2nd plastic disk
g. made another whole in the outer ring to fix sucker
h. connected the wires to 12 volt mobile charger
Thats all. It took about an hour to do all this and the cost is about RS. 150 (120 for charger & 30 for wire mesh).
Lets see the results. The equipment is costing 5500 on one of the onlie sites in India.
How much time should it run? What about only to run in night? Plants and fishes/invertebrates both produce oxygen in night.Solcielo lawrencia wrote:Do not run the device 24/7. The supersaturation of oxygen will result in hyperoxia, and kill all your fish and shrimp. Oxygen is far more toxic than CO2 in water. The concentration that animals start to die is ~20ppm.
How much time depends on how much O2 it produces and how much O2 is depleted by plant, animal, microbial use, and outgassing. There is no way to offer a suggestion without knowing this information. But to err on the safe side, maybe 5-10 minutes once per hour.SCORPIO wrote:How much time should it run? What about only to run in night?
