CO2 fertilization through the gravel via under gravel filter

[David Moses Heng]

Dear, all,

I read this in one of the books from C328 that this is possible and that it is being practise in Taiwan. Can anyone confirm this and the effectiveness?

Do you have pictures, or diagrams to show ? U mean pumping in liquid fertilizers or solid kind?

Hi David,

Quite keen to know how this would work as well. Any reference material on it?

Cheers

sorry for the late reply. Let me go get the book from C328 first and after which i wil post the pics here. But from what i have gathereed when i was there( one book was open for sampling), the co2 is in jected into the under gravel gas form. I did a check with Alister from Polyart and he mentions that Azoo has already launched a new product: CO2 enriched substrate.

Cheers!!

I bought 2 packs of CO2 enriched substrate from my lfs at Woodlands Vista Point for my 1.5ft shrimp tank. About $48 per pack. Can't really remember what brand it is. It's working thus far. I have a CO2 system installed in the tank too, but if i even try to turn the regulator to 1 bps, most of the shrimps would bite the dust. Initially thought it was the water condition or plant fert.

cool..but once it finishes we'll have to change the substrate?

Understand that the CO2 can last for a year or so. Dun have to change, just leave it and have a CO2 system set up to continue after that.
