I picked up a couple of power heads for circulation. Only problem is after time the suction cups no longer stick. What does everyone else do? If the tank was dry I would just silicone them in place. How about hot glueing to a small rock? What's everyone else do?
Thanks, Jim.
I would return it and get a maxijet. The Maxijet comes with a bracket you can hang from the tank. I was getting shocked in one of my tanks when I touched the lights with my hand in the water. I tracked the problem down to a Rio I had in the tank. Do a search you will find several posts about Rio's failing.
A neat trick is to glue the powerhead to an inexpensive cleaning magnet and then use both sides of the magnet to place the powerhead wherever you want it. You can also move the powerhead easily just by moving the outside magnet.
I clean the glass daily, and it seems most suction cups only seem to last less than a year. I was looking for something more permanent. I bought a rio 800 yesterday and wanted to attach it to the side of my overflow but no matter what it won't stay stuck on for more than an hour or so. I was thinking about the glueing to a 3" rock idea and just sitting it where I wanted. That way I can move it when needed and it stays put the rest of the time. I was just looking for ideas - I figured some people out thee has some "creative stuff. I'll keep checking back, Thanks - Jim.
I attached it with rubberbands to a rock and dropped it down to where I needed it - works fantastic. Stays put, no one can move it, don't have to worry about sticking. If it continues to be a success I'll glue it to the rock. I wanted to put a powerhead down low next to the overflow and couldn't get one to stay for any real time. This seems to be doing the trick and will look natural in a few months once the coraline covers it. I though about the magnet but wasn't sure if it would effect the powerhead since it's virtually a magnet it self. If that works then that's a great alternative for getting one in a hard to mount spot.
Keep an eye on your rubberband - they degrade ion saltwater fairly quickly. You may come home to find the rubberband broken and the PH pointed in another direction (usually straight down into your sand, but straight up at the lights is possible too, depending upon which would cause you more trouble
