When it comes to learning how to choose groundbait, black and dark groundbaits work well in clear water. They don’t stand out on the bottom, which prevents attracting unwanted attention from diving birds. Also, potential prey fish don’t like hovering over light groundbait patches on the bottom in clear water, because this makes them stand out to predators. You can buy special groundbait dyes if you need to tone down a favourite light coloured mix.
