Replacing Filters
« on: December 31, 2011, 08:22:09 PM » |

I just added a canister filter on my 75 g to replace a HOB power filter and am running it to test it and needed info on how long should I run both before taking off the HOB. There is other filtration going with another filter also, BUT I know it takes time for bacterial to colonize in the new filter. Anyone have an idea as to time how long ?

Thank you for the quick reply. I had no feel as to how long it would take to colonize bacteria in a new filter.

It's the SunSun 303 B , the same as Aqua Top rated at 375g/hr. I loaded it with extra pads, lava rock, and c nodes with a fine pad before the pump outlet. It's been going for about 12 hrs and seems to be doing fine. Came with a UV that I am planning to run 1 hr/week. I t has a spray bar which is new to me but puts out good water movement. I saw it on U Tube and wanted to give it a try. It's my second canister, had a Marineland C-160 on a 29/g. The second unit is a Fluval C4 which I really like. Will take the Emperior 400 out of service and store it. Probably needed a new impeller as water flow had slowed quite a bit.

I have a HOB that I will still be using and had no idea that the new canister would need to run for awhile. I knew I would lose some bio activity but wasn't sure how long it would take to have the bacteria colonize within the canister which should have far greater capacity. I should have moved the C nodes from the Emperior.

My new canister filter is working like a charm. Ran the UV for an hour and removed/clean/and replaced the Emperor 400 and saw a big improvement in water flow. Reused old media and will wait a couple of weeks before making it my spare as the canister filter colonizes the good bacteria. As a side note I wonder whether the gunk and snails had much to do why my nitrates stayed above 20 on the last w/c.
