Flow in propagation tanks

[bristlebasher]

Howzit Anthony,

I understand that you use airpumps in your greenhouse facilities to generate flow in the tanks.

I am thinking of using this in my new , small scale " for fun" ,prop wet room.

Could you provide more details and suggestions of how this can be done ?

Heat will be a major issue and I am hoping that this will place less heat in the water than a dedicated pump.

Cheers

Hilton

its really as simple as you could hope for my friend... 'tis really old technology. The premise is to use airlifts (like an old undergravel filter) to very inexpensively deliver a bulk portion of your water flow without heat issues. You will still need to use some electrical pump(s) to fully satify the systems needs and to finesse the total dynamic of water flow in the system... but even this too can be readily optimized (see my article on a closed loop manifold in the article "goodbye powerheads" on wetwebmedia.com or on advancedaquarist.com (Sept/Oct issue).

best regards,

Anthony

Thanx for the fast reply.

Obviously you are up early

Are they used on the same principle as an u/g or would they be able to lift enough water so that water from a sump could be moved ? Do you fit airstones to the ends or let the pipes empty unobstructed ?

really just like an UG filter... the lift depends upon the air supply of course and can be quite impressive (towards 3 feet with average blowers)... but is still most always used in-tank for circulation only. Its really not practical if even possible as a return from the sump.

kindly,

Anthony

Hey Anthony,

When I was at Harbor Branch. They were talking about the future would have no pumps. You would use airlifts only with aquaculture. He would not elaborate so I don't know if they were working on something or just a guess.

PS...Did you know that Rocky lost his GH in the Charley hurricane?

No way! :sad1:

Matt- He and his family are ok? Did their house make it?



**Hilton, forgive the off topic. Just concerned**

They are ok and their house made it as well........... the greenhouse, well that didn't take it so well.

Thank you for the link gpajon. How awful. Here is the RC thread about it.

No worries , glad to hear your friend is ok

exactly, Matt

it is the very thing I published in my BOCP1... although its not the "future" though... but has been around for many decades. Very efficient for much of the needed water flow to be created.
