I’m finally happy with the flowrate in my test bucket, no media is at the bottom of the bucket, so it was time to install the filter in the aquarium. This is currently installed in a 170l aquarium.
Three Angelfish, Kribensis and Albino Ancistrus sp. can be seen in the picture. This filter is driven by a Maxijet PH600 powerhead, I cabled-tied some spare filter media onto the media adaptor supplied with the powerhead. I usually obtain my cable-ties and other electrical bits and pieces from the following website JLB Electronics, a small business located in the West Country of England, fantastic customer service, delivery and good quality products, the cable-ties are excellent. If they don’t list it on the web site, just ask them JLB Electronics. This stops any large dirt particles getting into the media. I’ve mislaid the water deflector which helps to aerate the water, I’ve emailed PentAir for a replacement, so to aerate the water, I’ve fitted a Eheim diffusor, this ads some back pressure, so the media is not fluidized completely at present, to add additional aeration to the aquarium, it is necessary and important to do this because bacteria in the fluidized bed filter can reduce the oxygen content in the water to dangerous levels.
