First of all my lady friend says i have to much time on my hands and i should go back to work ,im 66,my kids say its aulztimers ,the fact is i have this big ol den that is just 'there'.and i want to take about a 12'x17'x 20" deep part of it and turn into a fresh water tide pool,
and have the normal pond critters.at least every thing i can find in tn.
my questions are ,will a sand filter ,say 2 55gal drums of sand be enough .
and i had thought of having 200 gal
of water dechorinating on the side.and will a water fall ,of sorts, put in enough air .or will i need more air.
i,m use to 75 and 100 gal
, but 1400 gal
i need some expert advice,
