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

Purchased to help Java fern from growing, and I have seen marked improvement in just a few months! Dosed lighter than instructions indicate, as I do water changes less frequently than it recommended. Easy to use with the pump head, and I like to keep the little pump lock on at all times to prevent toddler hands from spraying this all over my living room.

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

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.

Received the package with about a fifth of the bottle gone. There was a wet hole that burned through the package. It’s a good fertilizer, but the packaging was careless and put in an undersized box. A little disappointing paying extra for a quality product, and less of it.

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!

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.

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!

Get this package today, bottle is very dirty and doesn’t look new at all. There’s also a thick layer of sediment at the bottom, which makes it look like an expired product. I am going to return it.
