Replacing internal filter
Hi everyone, I just brought a new INTERNAL filter for my 20G, (480 L/H), I couldn’t take the (600 L/H) because it was too tall to be fully submerged. The old filter is internal too, and I also have an UNDER GRAVEL FILTER that has been working since the tank was established a year ago.
The OLD internal filter was recently cleaned (4 days ago) by replacing the polyster piece in it, and squeezing the ‘juice’ of the old piece of polyster over the new one, according to Lenny’s suggestion in his filteration article, so I don’t think there’s a lot of colonies in there yet.
The question is: can I replace the internal filter without having to run the two internal filters togeather for the next couple of weeks? will the UGF do the biological (Nitrifying) work until the totally new filter is colonized with sufficient N-bacteria?
BTW, I don’t usually run the UG and internal filters at the same time to avoid strong water current in the small 20 G tank. will I need to run them togeather to establish the new internal filter properly?
All the best, Noura
