Anchor makes plain, washed aquarium gravel - the sort of substrate you buy because it does its job and gets out of the way. It is inert and pH neutral, so it will not drift your water chemistry as the tank matures, and it works equally well as a plain gravel bed or over an undergravel filter.
Choosing a finish
- Multi Brown - a natural riverbed look that settles most community fish and hides detritus well between siphons.
- White - throws light back up into the tank. Striking, but it shows every scrap of waste and can make shy species hold to cover.
- Multi Mix 4-6mm - a coarser graded mix, better where you want water to move through the bed.
Before you buy
Work out the depth you want first. Roughly 3-5cm suits most freshwater setups; deeper beds look good but need more care to avoid anaerobic pockets. Heavily planted tanks will still want a nutrient layer underneath - this is a cap, not a plant soil.
