Review on 🌱 Ultum Nature Controsoil Freshwater Planted Aquatic Substrate - Classic Black by Heidi Smith

I have bought this bag twice before, one bag is enough to cover the bottom of my 3.5 gallon semicircular aquarium and it is perfect for the Growing Plants! The pieces are small and round, unlike some other substrates. For my 10 gallons, I mix this larger substrate with a smaller substrate to give the plants a chance to take root. other substrate mixes are cheaper, typically $25 for a 5 liter bag, that was $17 for 1 liter, but the consistency of the pellets themselves is more consistent.
