A lot of time, money and effort invested, with as many failures as successes - I think it's a passion not a hobbyGorgeous little beast. Congrats, it seems like you're having a great time with this hobby!
Hi Steve, being in the UK I can't get Turface but wanted a clay based substrate (though I know it doesn't have calcium benefits like some), so opted for Akadama. It's advertised as 3 - 7mm grain size - i'll get my calipers out at some point and confirm for you lolHi, I see you use Akadama in both your frog and plant growout tanks. Any details on granular size/grade?
Cheers
SteveC
