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.
Easy soil to use. Beginner Friendly. Does not leech ammonia. Does not break down after a year. Will need to add root tabs to supplement plant growth after a year or two.
With controsoil I can add more to my tank even with fish in it, with no problem of leaching ammonia etc. I like the fine grain for small or large tanks.
It’s got a nice brown color and it’s easy to work with. Not too much else to say on the matter. Good
My order was shipped and arrived quicker than I expected and it was exactly what it supposed to be. I would absolutely recommend aqua lab aquaria to anybody looking for aquarium supplies!
There is no - or not much - of an ammonia dump with this controsoil so i use it when I have to get fish and shrimp back into a new tank set up quickly. I have scaped the tank, flooded it , hooked up an established filter, and stocked the tank with fish, shrimp, snails all in the same day without any loses. I still do a 50% water change the next day. Maybe two days. But that's just to be safe. I have also added large amounts of controsoil to an existing tank with said inhabitants also with no problems related to ammonia leaching. Great Stuff, and grows plants well.
