Aqua tech 5-15 (Pictures to follow as soon as I find my cord.)
This mod merely increases the retention time in the filter. Why would you want to do this? GPH
flow rate isn't really a true measure of the filtration capacity of a filter. Suppose that in 1 hour your filters bacteria are capable of treating 100 gallons of water at average everything. You filter moves 240 GPH
. That extra 140 GPH
dosn't accomplish anything. The "retention time" Time in the treatment system is what matters. For mechanical filtration of course more is always better.
On to the filter.
Pull out of box. Open top and measure area filter cartridge was going to be inserted into.
I took an old and broken whisper 40 filter but almost any sort of sturdy water container that is plastic and can be attached to your filter will work.
I cut the pump area (which was broken) off of the whisper 40, sanded and washed the edges and then glued it to the side of the aqua tech 5-15. After a day I siliconed the inside of the join.
Allow the silicone to dry and then cut out along the wall between the aqua tech and the whisper. I made sure to leave a nice cushion on that part.
Insert sponge into filter. Insure it has been cut short enough top can close. Add a second sponge over the outflow area of the add on. Fill area behind the sponges with bio balls. Attach to aquarium and allow to run. Congrats! you have set up your own filter.
Maintenance: Every 3 months after a PWC
I take out the sponge and the bio balls and put them in a bucket with the spent aquarium water. Gently shake the sponge in the water to clear it. Put it back into the filter, then do the same with the bio balls. This should keep your filter clear. If you have a much bio load you may wish to do this more frequently. This is all the maintenance required.
