No i do not use a sump. I have a HOB and a XP3 Canister, and a skimmer. I have my nitrates about 15 but cant seem to get them below 10. But it never goes above 20. I have a problem with diatoms and i am looking to get rid of them and i know a fuge would help.
I have a 10 gallon tank but im not to sure of how i would go about doing that.
If i put the 10 gallon below my main tank and ran a tube from the main tank to the 10 gallon being gravity fed then i would put a powerhead in the 10 gallon to pump the water back up into the main tank. Im afraid i wil have a flood doing it this way.
