A nice low flow venturi seems like a wise idea.

IU- I'm heading to Albany to redo the 125 for Guy this SAT.
I've never used the African root in any scaping before, but will this time.

I recently got some Aquaticmagic.com ADA beetle knock off diffusers, the 1000 and the 5000's.
10mm and 50mm basically.

You can check out the effectiveness in the coming weeks with good flow and the mist method.

I suppose the tank is big enough to add a 3/16" venturi cheapy Kent.
I'm going to do all disc though, the set up is perfect it for it and the tank has lots of plants for scaping very close by

The AM disc seem to be every bit as good as the ADA stuff but about 4-5x cheaper.


Seems like if you could have a little bubble chopper like the needle wheel thing/ides but driven faster by flow rate, that might be better for low flow applications than venturis.

No pump, just a drive system that spins the chopper impeller wheel around, that would not take much energy to zip the speed of the impeller fast.
The constriction from the venturi does drop the flow down considerably.

That's the rub with the darn thing.
I use 2 seperate large powerheads for the large behemoth.

On future Zoo exhibits, we will use venturis and disc, the mix gives the desired results like a 20 gallon tank in terms of getting enough CO2 in there fast, great response time.

Larger tanks are a bugger to get enough CO2 with high lighting.
I know I've solved that issue now so I have no problem doing anything massive. If you control the CO2 effectively, then the rest is easy, dosing/lighting/water changes etc.

Massive planted tanks in the Zoo's will be awesome.
BTW, Tenji, the group I work with for the engineering is doing a lot of the Steinhart tanks in SF's revamping of their Aquarium.

Mark might have me do some of the work there.
We will see.

I have the wood, I have the rock, I have the CO2, I have the lighting, I have the soil, I have the routine/dosing/ferts, I have the plants.

Not much else will stop me from promoting planted tank world domination

If those in power have them and like them, then the rest will follow.
