S.W.A.P. [AC] vs Traditional DC

SWAP vs DC

My basic conclusions........
One does not have some overwhelming advantage over the other in all situations.
Each has comparative advantages and disadvantages under different circumstance for different demands.

SWAP :

[Minus] Takes longer [is slower]

.
[Plus] SWAP doesn't build up Silver/hydrogen bubble clusters on one electrode that can lead to stuff dropping into the water that looks worse than a few sparklies.... which are the same thing of a different size in a different place.
Reduces silver oxide buildup on electrodes to a minimum. [the black stuff]
Large batches don't have large batch/ time related Silver/hydrogen bubble cluster buildup problems that can fool the auto off circuitry and don't drop chunks and fluffies into the water as crud laden electrodes are removed that look worse than a few sparklies.
Very Strong and very large batches are easier to make without problems.
No silver slick on the surface from surface tension transfer.

[Neutral] May or may not produce more "sparklies" that later settle and/or disburse into particles that appear to be exactly the same as DC made particles.
* If stir speed is just right for the container size, very few sparklies are made with both modes.
* Sparklies are nothing more than "particles" trapped in very small hydrogen bubbles..the bubbles cluster, not the particles.
*The mag stir running a liter with a small spinner is about perfect

DC:

[Plus] DC is faster.
Smaller batches look nice sooner and can be used quite fresh.
* Perfect for those who believe [as I do] that very fresh CS has properties that older CS doesn't and make very small daily batches and think that sparklies are "bad". [As I don't]

[Minus] Electrode deposits can get really heavy.
Strong batches sometimes develop a silver slick on the surface that can foul meters.

[Neutral] End results after 24 hours are pretty much the same either way with the same variances between batches

Commonalities:

Sparklies, fluffies, floaties, chunks and slick are all the same thing...silver particles trapped in the surface tension of various water interfaces...not necessarily larger "silver" particles.

Auto off determines ionic content.
Particulate content varies with overall PPM and several other factors common to both AC and DC operation. DC tends to keep that content on the electrodes but doesn't always do so. SWAP tends to put it into the water.

One could start with DC while things are going slowest, then switch to SWAP as electrodes blacken.

It's a matter of preference within individual circumstances.
