So I went with this mod: Cut out some filter to jam between the Intank Media rack and the tank. Fits like a glove. Also did the egg crate to narrow the channel of the water flow (CA glue melts the egg crate so watch out!
Middle rack is chemi pure blue (2pcks)
Bottom rack is Phosguard. Is that supposed to float like that?
2nd chamber is the stock fluval bio rings in the pouch.
Any thoughts on this set up?
