My dad has a DIY
tank that's about 200 gal
. It' a big cube, about 3 ft on each side. What do you guys reccomend for filtration on a tank this size? Menards has a pond filter on sale for $129 that's rated for a 3000 gal
pond. It's just a giant canister filter with a couple compartments for media. Has anyone used a pond filter on a big tank? What do you suggest?
