Well just getting back from a trip to the LFS
I inquired about changing my set up from canister to a sump and the answer I got was I it's not broken don't fix it .
I don't get nitrates above 10 ppm
but for the extra volume and for pods
I thought it would be a good idea .
A few questions :
1) besides routine maintenance what are the pros and cons of a canister compared to a sump .
2) what should I have inside the canister to filter and polish but not to trap nitrates ?
I have ceramic hollow hollow pieces , about 2" of floss and a dense blue foam that is 2" thick .
I'll take pictures when I get home ,
There is a 1/2" can under the ceramic and the bottom of the canister and again between the floss and the ceramic.
Any suggestions ?
