i have a 150 gallon tank with dual overflows. 8 blue ziere fronts and 2 live caught blue ziere fronts that look great. then i have 15 peacocks which are 3 different types then 3 bristlenose 3 gold nuggets and 6 white and orange band trouphes and 5 blue dolphines. i do water changes every week at 30-40% and all my water test are always looking great. my tank has a 40 gal sump which before my sump there is a tank that all my water goes thru a 100 micron bag as a prefilter before the water gets to my sump. then in my sump i have 3 200 watt heaters, filter floss about 4 " of it then bio balls the 4 bags of carbon and ammonia flakes that my water gets pushed thru before it goes back to the tank. my return pump is 1450 gph. I see on here people will have a large sump and then on top of that will have canister filters to assist in the filtration. is that something that i will need look in to for my setup. i currently have 2 100 micron bags that i rotate every 4 days while i wash the other. i am just new to the sump setup
