Flourish Tabs – 40 fertiliser tablets

Flourish Tabs are root fertilizer tablets for planted aquariums, intended for hobbyists who want to feed plants directly through the substrate rather than through the water column. They suit both beginners and experienced planted-tank keepers who need a single product covering the nutrient needs of their plants.

Why it matters

• Phosphate- and nitrate-free formula: the tablets contain no phosphates or nitrates, the nutrients that tend to promote algae growth.
• Delivery to the root zone: tablets are pushed into the gravel, so nutrients are released close to the roots where plants take them up.
• Slow, enzyme-driven release: nutrients become available gradually as plant roots act on the tablets, which reduces the need for frequent dosing.
• Ready-to-use dosing: 10 tablets are enough for a substrate measuring 150 x 60 cm, so calculating the amount for a typical tank is straightforward.

What it works with

Flourish Tabs are designed for substrate-rooted plants in planted freshwater aquariums and are dosed by substrate area, so the 40-tablet pack is matched to a tank bed of roughly 150 x 60 cm. Per the manufacturer, the tablets do not change pH; in very soft or unbuffered water they may have a mildly acidic effect, similar to peat. Use them together with a gravel or sand substrate in which the tablets can be buried.
