I use a home made filter.. PVC pipe
Enterance has a stainless or PVC drain cover, then some filter floss (Fish Isle at Wal*mart) then a bottle of activated charcoal (The plain stuff, not the algae control) then more floss then the other type of drain then the outlet.. The body has male/female connectors so I can replace the non-hardware (Floss/charcoal) makes an amazing difference but here where I'm at now.. NOTHING takes the bleach taste out, the city (Actual city, not park) over chlorinates.
So i fill the tank, let it sit a bit, and then it's good (like 5 minutes)
Home is where I park it!
