Giant Pink Gourami – Billabong Ontknoping

Still testing...

The siphon gurgles but doesn't seem to want to do the siphon-action and suck out the water faster than it comes in.

Hmm...

Time for fine-tuning:

a) adjust the Aquael pump flow (either up or down)

b) add an elbow on the bottom pipe to encourage formation of a solid flow of water

c) alter the height at which the siphon is supposed to start (ie. lower the level) as there's a good 10+cm of water above the scoria.

Urgles...  watching the water level change is worse than watching grass grow !

( is going to ignore the siphon on the weekend and re-pot water iris plants for the GPGs instead )

Billabong Re-vegetation

After deciding to ignore the BBF & siphon (as seen above), Grover resurrected one of the Elephant Ear Islands today -

This will be planted up with Elephant Ears and floated on the Billabong when the blue cover comes off in Spring.

Theoretically, Spring is already here in BrisVegas, but the EVO is still running on & off to keep the temperature at 26degC. 

So don't mind me if I keep the cover on for a little longer...

Cheers,

Grover

(will be getting some new varieties of water iris from Watergarden Paradise Nursery some time soon)

Right... back to the Siphon...

A combination of tinkering with the actual plastic of the siphon (adding the 90deg bend at the bottom, and using silicone to seal the top cap of the "bell" part), then  adjusting the flow rate from the Aquael pump, and temporarily setting the timer seems to have gone close to getting it sorted today!

It not the sort of thing Grover is going to video as the entire cycle takes about 65min, and he realizes there's only one exciting bit in the whole thing - where the siphon suction actually breaks and the water stops gurgling. Thrilling it ain't :?

 

Here's the BBF in mid-cycle, as proof that the water actually does rise and fall -

and here's the scientific documentation recording the parameters used for experimental purposes (the numbers are in minutes that Grover stood there, bored, but watching) -

As you can see, this is well-documented for future budding siphon-builders :typing:

Grover has rejected the "Fast" timing in favour of the "Mid". Some of the technical terms may be hard to follow, but 'gurgle' is clear; 'fill & stop' or 'fill & down' are a bit tricky; and 'empty break' you'll need a science degree to master :yield:

Cheers,

Grover
