Some of these places do 100% daily water changes, with most of their tanks running on one small sponge filter or no filter at all.
There is never any type of "phantom crash" that some people believe can happen and there is no worries about any lack of beneficial bacteria with each and every water change.

Facilities like these disprove some water myths that some people believe.

They still have to dechlorinate though :).

I forgot to ask Juan at the CCA June meeting how he does water changes in Mexico. The water there is basically watered down bleach...EXTREME amounts of chlorine (at least in the area I was at on the Yucatan Peninsula in the state of Quintana Roo) that rivals the smell of the olympic's pool maintenance rooms...

That's awesome though. Now THAT'S how I want to do water changes (minus draining all the way to the bottom) in my garage, just let all the water spill out of my garage (or via hose) to the gutters or lawn.

And your floor gets washed at the same time!

some tanks had little water left, doesnt that stress that...or having the jet of water hit them while they are laying sideways?

Oh, this isn't new. Asian discus breeders have been doing this for a long, long, time. There is no crash from lack of beneficial bacteria because there is no ammonia in the tank -- the water is replaced daily, some do it twice daily. Hence, no cycling of a tank or beneficial bacteria needed. Most don't use filters, b/c the daily water changes take care of everything. With 95% - 100% water changed (to the point where, as you saw, the discus lie on their side and barely enough water covers them), the fish are able to be fed frequently and heavily, have their water changed continually, and grow quickly and very big in size. As for stress, sure, it probably stresses them briefly (my discus in grow out tanks would get stressed with my 50-60% water changes 3 times a week, but fish gets stressed in the wild, in getting netted / moved in our tanks, etc, and they recover and do just fine) but the benefits of the constant water change outweighs the brief periods of stress.

I love this technique….I just wouldn’t want to be wading around in that water with all that fish poop like they are doing. :lol:

I agree. They could have build a drainage pipe or draining canal... bet yah that place smell, but then considering it is in asia, might be an open space.

Thats cool. The Discus don't look to thrilled about it.

The reason they do those water changes twice daily:
