Does it matter how long the filter tube is
like the length and how close it is to the ground, would it affect the ability of the filter and suction? right now its a good 2 inches above the gravel.
I think it's up to you as to how long you want your intake tube to be. Over the years, I've had them at every length and I really can't tell a difference in the filters ability to function. If you have multiple filters, then I would recommend 1 short, 1 long. This way you get filtration close to the top and close to the bottom.
I agree. The length doesn't matter, as long as the intake remains above the filter, gravity will continue to siphon.
My only thoughts are to do with circulation. Water comes in at the top, so I try to have my intake as low as possible.
The other consideration would be your substrate. If you have sand, you may want to have the filter intake a little higher so as not to suck sand into the filter.
I like mine halfway for emergency purposes. In the unlikely event of a filter malfunction you'll only loose water down to the intake. It's happened to me twice and I was glad there was still plenty of water left for my fish to swim around in. (My fault the filter malfunctioned as I didn't put clamps on the hoses and one came off)
My intakes are generally within 2 inches of the bottom.
I have gravel so it won't matter, so I might add the final piece which is atleast 1'' long.
Ken stole my idea. I usually have one high and one low. I also like to put something on the wall of the tank so the intake tubes stick out from the wall.
I run mine 1 -2 "from the substrate.I do have 1 that goes in the gravel.I wanted to try it to see if I notice a difference.But haven't noticed any difference so far.
the strainer is buried in the gravel? That's a neat idea... I bet it might work well with an UGF... Connecting the filter intake to the UGF?
On my largest tank I do the same as Ken and Luke. One is midway down, the other one is several inches above the substrate.
Jaysee,It is half way in the gravel.I use all hobs on my tanks
