haha, ya thats the thing, i am doubtful it will work [letting the water seep and force through the sand before entering the next compartment], doing a vote to see any 1 done it before and how's the filtration [if it really works and not blocking the water flow]
SeaGel is a blend of MatrixCarbon and PhosGuard, i poured around 250ml inside, have been using it for my last setup therefore using it here too [it's ok i think], using it because it's cheap haha.
maybe will invest in biohome, any bros know where to get for 1-2kg <-- is it enough? and whats the price you bros get it.
there's C328 nearest to me maybe i can check it out there.
Any particular step i need to do for biohome? just put it inside and let it cultivate?
