Anti-Foaming Agent

[cabrera]

is there actually any answers for anything on this site, i mean no disrespect but i read nothing but "questions", "maybe's" or "perhaps this might work"
is there anybody on this forum thats got any confirmed experience with catalysts ? if anybody does, im simply wondering if anybody knows exactly 1. whats better, potassium hydroxide or sodium hydroxide
2. where can i buy it locally
3. and exactly (or even approx) how much do i mix in per ltr of water

Brendon,
Definitely potassium hydroxide! Like Lee, I also use a 28% mix and I control the amperage draw with a PWM.
Finding KOH locally has always been a problem. You want to use food grade KOH. (at least 90% pure) I get mine from.
Essential Depot.
They usually deliver within 2 days and their quality is excellent!

on the subject of electrolytes, i would recommend somebody to try sodium tetraborate (aka Borax). it should be available in hardware stores.

it may be useful to have a mixture of Borax : KOH of about 1:10 (so for 280 g/L (28%) KOH, use 28 g/L borax)

Definitely the best I have worked as an antifoam, SS wool is sold in the supermarket, placed in a small tube attached cap with two of them with PVC and the other only to pressure, also serves as a "fuse" of pressure.
This stops the foam and serves as Drie
