i recently purchased a new bio wheel filter 150, it is 8 inches long and the hole at the top of my tank has only 7 inches to spare, how can i make it longer? can i cut it somehow
oh, here are some pics. the hole is gonna be where the filter is, im planning to make it longer, u prob. kno already that there are fish in there. and water
oh btw, i saw the video of ure gar and that thing's sick!
Lower the water level enough that you could mask off the entire top of the tank so no debris will get in it. Then make your cut, and vacuum out the shavings. I think this would work with plastic, but again, I don't know much about acrylic.
I generally discourage people from cutting into their aquariums. What I would fear in your case is cracking the acrylic. I'm sure someone around here works with the stuff and can give you pointers however.
That being said I have to ask why you want to change filters? If you believe you need more biological filtration you can always step up to an AC50. I tend to get the next size up when buying filters. Mechanically speaking I don't think you'd see much a difference in an AC30 and a penguin 150. Also if you need more current in your aquarium I'd probably add a small powerhead or 2.
Ah now I get ya. I'd still like to hear from someone who works with acrylics on this thread. Where I used to work we had some acrylic fixtures and such and when they cracked they generally cracked very badly.
the dremmel is just that easy...use the 561 or 9901 cutting bits, or the 650 router bit(dremmel brand #s)...as said before...lower the water...cover...and cut...take your time, and keep the radius corners
