Flourish tabs are a gravel bed conditioner for your planted aquarium. These tablets are slow dissolving tablets designed to be inserted in the gravel bed of the natural freshwater aquarium. Each tablet contains a rich assortment of important trace elements, vitamins and amino acids.

They are rich in iron, manganese, magnesium, calcium, potassium, insitol, choline B12, biotin and other factors that have been determined to be beneficial to aquatic plant roots. Contains no phosphates or nitrates that would promote algae. Each bag of 40 tabs is sufficient to fully treat a 12" x 30" gravel bed eight times.

Directions: Insert one Flourish Tab in the gravel for every 10–15 cm (4–6 in.) radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed. Push each tablet midway into the gravel bed. Add new tablets once every one to three months for optimal plant growth. Tabs will not alter pH, but, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.

I like that you only need to put new tabs in every 3 months. A lot less maintenance as a result

fab fertilizer for fishtanks!


easy, dependable, thorough and lush is what you have with these fertilizer tabs. Convenient once every three months dosage provides substantial nourishment for growing plants, stabilizing aquarium chemistry and encouraging lush greenery in the tank.

Flourish Tabs Great for the Tank


I love the convenience, quality, size and shape. Easy to pick up with my big tweezers and bury in my 75 gallon. They are particularly good for plants that root.

for lush aquarium this meets the challenge!


Flourish is a convenient safe and concentrated fertilizer that does what it says. The plants are lush, green and healthy. Does not harm the biosphere in the tank the fish are unaffected by its presence but the plants are remarkable in their growth. A wonderful product for the planted aquarium
