Question about power filters (HOB) and intake tube length

[tomdkat]

When choosing a power filter for a 55g aquarium, how important is the length of the intake tube? I notice the MarineLand filters (Emperor and Penguin) tend to have shorter tubes than the AquaClear filters, for example.

Is it important to have an intake tube that goes deeper into the aquarium, closer to the gravel/substrate or is it preferred to have one that stops at a mid-water level?

In other words, "does size matter?"

"Danke for the smokes"

I've had trouble starting an emporor in any aquarium. The water MUST be near the top capacity of the tank, or it will not start.

In answer to your question, as long as adequate circulation of the water in the tank is provided, any size intake tube/hose will work. Personally, I like Marineland's Magnum 350 Deluxe w/biowheel the best. It makes my tanks sparkle. (Also comes with an extention tube for the intake, for the "deeper" filtration you want.)

That's the canister with the biowheel that hangs on the tank, right? I've never used one but have been intrigued by the biowheel part.

One of the basic functions of a filter is to remove particulate matter. Generally, particulates settle to the bottom. The closer to the bottom the intake is, the more likely it will suck up the heavier particulates, provided the current is strong enough to move them to the intake. As long as you gravel vac, you'll be alright either way.

I run two AC110's on my 75gal, I have one uptake all the way down to the substrate and one mid-level. The lower uptake gathers the most detrius.
IMO single uptake tubes should be as close to the substrate as possible.
Substrate can be sloped to direct feces/food towards uptake, a power head or return flow jet/spraybar can be used to help keep particles in suspension longer to facilitate pick up by uptake.
