Use in my aquarium, and plants are growing very well! Rapid growth!GoodWorks as advertised.Great Product works great been using it for over a year nowI bought this thinking I was going to save money over Seachem Flourish. Flourish is $16.00 for 16oz, Aqueon plant food is $11.00 for 17 oz.... But with Aqueon you dose 2tsp per 10 gallons.... with Flourish the dose is 1tsp per 60 gallons both once a week. So you need 12x more Aqueon every time you use it.Item came without a lid . So If I open the seal there is no way I can keep it sealed anymore.I use this for a water column firtilizer bc not only is it less expensive than fluval or thrive but it work just as well and doent need to be used as often as is stated on the bottle. Fluval fertilizer is not complete and you have to buy a lot of other vitamin liquids to make it work well. Thrive is complete Firtilizer but very expensive to use and doesnt last as long in the water column. I use this product with low light plants and they are very well fertilized once a week with this fertilizer. I recommend this product fr nano tanks with low or medium light water column plants like Java fern, water westeria, Anubis, and other floating plants to maintain their health and not harmful to fresh water fish.The lid on this bottle leaks when shaken...for a product that says shake well on the bottle it's a little annoying.Added to aquarium didn't see much difference in the aquarium plants, product was very chunky when added to water.Not sure when aquarium ferts got so pricy, but this seemed competitive enough. Arrived well packaged and no leaks at all.Este producto me ha funcionado bienLas plantas se ven sanas y han crecido bastante bien ,la verdad no he probado otros productos pero en mi opinión me ha funcionado.The plants are doing well so no complaints. Price is good.
