JBL Florapol and granulated peat questions . . .

[Wookii]

• Has anyone used this product as a base layer, particularly under sand or other inert substrates?
• If so, does it live up to its marketing and really provide a long term nutrient supply?
• Also does it stay in firm/solid granules, rather than break down in the water over time?
• Does anyone know what it is made of, and are there any better alternatives?

Fluval Aquatic Peat, 500 g (17.63 oz)

Peat Granules provide an all-natural way to soften aquarium water and achieve the pH levels required for breeding and rearing certain tropical fish. Peat contains humic acid, tanning agents and trace elements that are essential for various life processes. Highly concentrated and compressed for...

EHEIM Torf pellets 450g

Depending on which type, chemical filter media control the pH-value and the water hardness (peat) – or reduce the phosphate level and inhibit the…

The idea being these will be easier to handle and use, and easier to contain under a sand top layer, than the light loose gardening peat.

My plan would be a mixture of crush lava rock, the Florapol above and the peat granules as a nutrient rich base layer, but I'd welcome suggestions of alternatives?
