And Tom, don't you use an inline system on your 180, with external pumps and a mazzei or did you switch it out for a sump?
The mazzei is fine for in line applications using canisters, but, you have to be more careful, with sumps, much less so. Ask yourself why that might be.
Also, looking at the mazzei implementation/addition, the sump design is much easier, can use less electric etc.
Not the wrong thread at all.
Very applicable to the selection of a mazzei and CO2 misting.
Basically you can get more out of it and for less, while I decided to really pursue the canister approach, and I still use them etc, I also look at other systems and weigh the trade offs there, not everyone is going to need/want a 150Watt external pump, big OC canister etc.
Many use wet/drys or sumps.
I have both so I can compare notes.
I also have a nice O2 meter and a CO2 meter.
Few, if anyone here does.
My concern is more for the fish and the O2 levels/CO2 levels.
Some have rightfully warned folks about gassing their fish.
Not hard to do with a canister and mazzei.
