tetra whisper 10-30 sufficient for each bucket

Sais it's good for 10-30 gallon tanks. I think this is a Canadian model or something cause the packaging and labeling is different from the american counterparts online. In the US they have tetra whisper 10, 20, 60, 100, etc. So I'm assuming this is the equivalent of a tetra 30 in the states.

Also you guys think I would be better off with 2 airstones or some porous tubing(punctured with needle).

I personally use a "10-30" gallon pump if I remember as well ( bought in US ). I just remembered I made sure the lower range ( 10 ) was double my actual size ( 5 )... actually in a 5 gallon bucket you have about 3 gallons of nutes so you are actually roughly 10x over the adequate level.

I use 2 6" air stones one on each side of the net pot, either that or I use Ts to connect 4 of the cheap fish ones

Thanks for the quick response much appreciated.

Not a Whisper pump fan. Bought 2 and both tore a diaphragm right after warranty expired. Tore them apart and reassembled one. That said, I use a 60 gal Whisper pump for my 12 gal res and a 10 gal Elite pump for my 2 gal bubbler.

Surface turbulence is where oxygen is absorbed. Get that surface rolling.

Hmm so the roots only absorb oxygen on the surface? So aslong as the surface is evenly boiling I should be good? I was unaware of this and thought that turbulence below the water level was just as important.

Unrelated open question: Is it possible for the water to get too cold? My buckets are gonna be sitting on the basement ground and I heard 68F is optimal but what happens if in the night it dips to mid or low 60's? Thinking about running my light at night because of this...that and the lower electricity rate.

No. Sorry for sloppy writing. Surface turbulence is where oxygen is absorbed by the water. Bubbles disturb the surface and cause circulation, spreading the oxygen throughout the res. This allows roots at the bottom to breathe even though submerged.

Waterfalls are the most effective means of aeration. Two turbulent surfaces crashing through a third.

I didn't notice a stall till temps hit the 50s. A small aquarium heater will maintain temps at 68º.

I agree with freezer except to me surface includes all surface area, regardless of what gravity is doing, so I would postulate that o2 is absorbed in all areas air touches water, mostly at the surface... Not sure if thats what you mean exactly or how you would define surface... regardless more agitation at the "surface" allows the o2 to dissolve better. plus you dont want standing water for a variety of reasons other then just dissolved oxygen. PH "hotspots", nute "hotspots" ( for lack of a better term when your nutes settle on the bottom for ex. ), algea, pathogens etc

Nice explanation. Thanks man.

That's why I mentioned waterfalls. Waterfalls are a sheet. A sheet has two sides or surfaces. Because they're falling, they're both turbulent. When they crash through the water body surface, that's a third turbulent surface.

While airstones are less effective, they take up less space and are quieter than waterfalls: Two strong considerations for cab growers.

So with the waterfalls is there some thread on here that explains the best way to create one? Don't bio filters need to be close to the water level? Whats a good way to create a wide sheet at a higher distance from the surface?
