The original filter and lighting will not be used. All that i am retaining from the chi is the tank itself. it is going to have pressurized co2 injection along with a small canister filter (still undecided on which one) for filtration.
Sorry this reply came a little late, but you can see picture of the way I modified the lighting on the Fluval Chi. Just ditch the filter it comes with and replace it with a submersible. I added a 10x10 glass lid with modified shelving pieces I got from Lowe's. I also used a $7 off petco coupon at Petsmart and got the Marineland LED lighting for $25 and it is powerful. i have it on a diurnal electric timer. I ordered a CO2 injection kit and it's coming this week. So hopefully I can get my hairgrass to take off (I've had a couple runners so far).
