Aquarium Pharmaceutical (API) Water Test Colour Cards

For those of you who have mislaid the colour charts for checking your water tests using API (Aquarium Pharmaceuticals) I have made a copy of mine and made them available for you to download. If you right click and then click "save as" you can save the images to your computer. I would suggest using a good quality colour printer if you intend and printing them out.
