well i dunno how many gallon can my tank feed in

but the size of my tank is 2 feet width n length n also 1½ feet height

how much gallon of water can feed it??? i oso dunno..hahaha didnt count

it is a DIY tank actually....did it myself
i'm now using a filter n i think it is a canister filter

if i put in more plant....i think it will make my water changing process to be more difficult...wouldn't it be???
