Fluval Plant Stratum is the ideal substrate for planted aquariums, featuring a light non compacting porous structure. Its ideal properties as an aquarium substrate are highly beneficial to nitrifying bacteria which rapidly colonize the vast porous surface, providing optimal water quality for fish. Stimulates strong plant growth. Plants flourish as their roots easily spread and take advantage of available nutrients. Help support a neutral to slightly acidic pH. Will not discolor water and helps to control organic discoloration usually present when natural driftwood is used.
