Re: invisible filtration for small planted tanks
Bill,
The link shows what's locally called IOS (Internal Flow System) and regardless of what's said, I will be using this filtration for my bedroom's 4tier 3ft setup. Henri filtration, which worked extremely well in my main rack, will also run simultaneously with the IOS (partially diverted output from the powerhead in the IOS will drive water up the Henri).
I don't think maintenance is a big issue if the prefiltering media for the largest debris, is at the front or easily accessible. It is then only a matter of rinsing this when necessary. The rest of the media or compartments should ideally be left undisturbed. If the sight of bacteria-coated media is considered an eyesore, adhesive based veneer (material of your choice) can be used to hide it.
Instead of the IOS running the width of the tank, it can also be rigged length-wise, albeit sacrificing some tank depth-of-view. A sculptured piece of black foam can provide a nice background while hiding the various compartments.
Go for it, Bill. Systems like these are very low in maintenance and it's a worthy Spring project. I'm a sump-nut and will be comparing notes with ya.
I'm back & keeping 'em fingers wet,
Ronnie Lee
