You could control your current manually with a ceiling fan controller wired in-line on the hot side of the 110v input. You'll need an accurate method of measuring the amps to the parts, and then hand control the current throughout the entire run.
An automatic charger doesn't work for this. Instead, go for the cheaper manual model.
Just so you know, red is one of the harder colors to master. Anodize too long and it will turn out chalky. Anodize too short, the red will be pink.
Different alloys anodize at different rates. 6xxx and 5xxx go for a full 1mil according to the 720 rule. 2xxx and 7xxx, go for .75mil.
Also, watch your acid concentration and temperature. 1:3 acid/water, @ 68-70F.
Use aggressive agitation too.
