Default RA4 printing with Tetenal - A warning!

I have recently had to change my RA4 baths in my Nova processor because of under replenishment. The replenishment rates were not given in my 5 litre kit so on advice from Tetenal they advised me about 10cc per 10x8 print would be adequate - WRONG!

Since then the company has undergone changes and the new RA4 kits are different. That 10cc replenishment may have been OK for the old previous formula, but that has now been changed to make it odourless.

The instructions in the new kit I am using states that a 5 litre kit will be sufficient to print approx. 230 10 x 8 prints which equates to a replenishment rate of slightly over 20cc per print, a significant difference. This also applies to the bleach fix as well.

With this increase in replenishment volume makes the Tetenal kit which was already pro rata, roughly twice the price of the Kodak Ektacolour RA4 20 litre developer and Blix 20 litre bought separately. Now double the price again because the replenishment rate for the Kodak is still 10cc per each 10x8 sheet of paper.

Once this Tetenal kit is finished I am going back to Kodak.
