Sorry about the delay folks. The new instructions are posted in the online manual.

You can convert to the new system with an existing set-up. It uses a much weaker concentration of acid, so you just need to dispose of your old solution and mix up new. The ratio is 3:1 distilled water:acid.

The new system uses a low and slow method. Instead of letting the process draw what it needs from the power supply, you add a rheostat (bulbs, rectifier, dimmer switch etc) to control the power much in the same way as plating. The system needs 30 milliamps per square inch area of your part. You anodize for 90 mins.

This has the advantage of NOT heating up your acid bath as well as giving you a consistent, easy to follow process. The reduced power means less heat in the bath, eliminating the need to cool the tank and eliminating problems with pore size caused by temperature fluctuations.

The weaker solution means less fumes and safer handling.

The results are a consistent film thickness and pore size, which of course means consistent dying results.

It's a greatly improved method.
