aqua clear is hands down the best option. i do the craziest stuff with mine (double carbon, chemi-pure, amonia pads, phophate remover, organic absorption resin). the truth is, for larger operations, if u want to have strong and legit filtration, you wanna tripple your tanks capacity in filtration (i have 250 gallons of Aqua clear filtration on my 75, and i have a gorgeous tank with PERFECT levels)
