Controsoil Fine Soil - UNS

20 items left

Choosing a quality substrate is an essential part of a nature aquarium as it provides vital nutrients for lush plant growth and helps balance water properties by decreasing the hardness/pH to optimal levels for aquatic plants, shrimp, and most tropical fish.

Originating in Japan, Ultum Nature Systems x Marfied Controsoil consists of high-quality natural soil and volcanic ash. It’s common for competing substrates to cause ammonia levels to spike. While this helps “jump start” a tank and promotes plant growth; it is toxic to livestock and can cause unsightly algae during initial stages of an aquarium set up. Controsoil provides the perfect level of nutrients without excess. Many have successfully added livestock within the first 24 hours of a newly set up tank with this substrate without worry. We do however suggest making sure that ammonia and nitrites are eliminated before adding livestock.

Controsoil is available in various granule sizes and colors to accommodate user preference and aquatic plant choice.

    Works as intended

    Got four bags to fill my 65g. Water rinsed clear and soil did not float too much from the bottom. Currently growing hairgrass and crypts and they are doing extremely well. Will see how long soil could last with basic plant supplement tabs.

    Aqua soil that doesn't turn water brown

    This is great soil that doesn't sludge up the water and does not leech a lot ammonia. Plants grow like crazy in this.

    I'm really impressed with this soil! I've only used gravel before, I'd never go back. This doesn't show all the funk and **** that gravel does and it is super easy to clean.
