Ultum Nature Systems Plant Food - Live Aquarium Plant Fertilizer for Fish Tanks - Provides Essential Macro and Micronutrients for Aquatic Plants (500ML, MIN)

Love this plant food for my planted tank. My plants are really loving it too. Like the simplicity of just adding it and not needing to measure it, just pump and go.

High quality aquarium fertilizer at an equally high price. I'll grant that there is much you need to keep out of aquarium fertilizer, and unusual minerals to go in, but a pound of Miracle Grow (don't use that in an aquarium for God's sake!) runs about $10, there should be a low cost aquarium fertilizer on the market. I boughtr the Ultum because it is a highly reputable, quality brand. But the price? Ouch!

Arrived leaking, and about 20% of the fluid was missing. Other than that, it does it's job. Fertilizing plants in my tanks. I'll be switching to Seachem in the future, since they seal their products. Maybe I was sent a previously opened unit, which is honestly worse than if the company just doesn't seal their product.

Just got it and have been using it for a week. Checked the water parameters and it is really good proportions, hard to maintain if you use separate additives. I only add Fe. So waiting to see how the plants react to it!

Super potent.Be careful using this and if you do you’ll need a phosphate remover or else you’ll get algae.

Looks a little used and bottle seems a bit dirty

Works excellent and particularly if you have Contrasoil as it’s designed to add nutrients back into the Contrasoil. Great product.
