This sounds like important information. Where could I obtain the anode? Thanks, Terry
I don't mean to alarm you, Aqualu is a great brand from what I heard; I just have lots of experience in aluminum & steel interactions, especially in the situation where there is contact, and a source of ground to interact with O2 to create electrolysis (or galvanic conduction). That is why your tub came with stainless harware and unique rubber body mount spacers - to reduce contact. By adding a pice of Zinc, which is much lower on the galvanic scale than steel, and lower still than aluminum, the electrolisis happens to the zinc, and not the body mounts, seams, etc.
Now this is not going to happend overnight, or even in a year but with a small current (any residual from wiring, stray voltage, normall stuff.), oxygen and regular steel, the point of contact with the most current will deterioriate into a crumbly substance that loses it's integrity. Most of what I am talking about refers to experience in the marine industry, which is accelerated due to saline (which speeds up electrolysis as it is a better conductor, and positive isotope) as well as my current field, where optical frames have been tried in various configurations for years, all resulting where there is an interaction in the lower galvanic medium failing (thus why we use alloy or titanium).
Now I know this is most likely TMI, and I am getting close to a BrotherRob length of post
, but it might be good idea to pick up a small zinc anode from anywhere on the net, and weld, or wire it directly to the tub (not steel) take a look at it now and again and you will be amazed as it starts to get smaller, and pitted due to the galvanic conduction of the two metals.
That's my 4 1/2 cents.
