Corner filter suction cups

[lauren]

My axolotl graduated to a filtered 10 gallon tank today (He had been living in smaller container as a juvenile with water changes every other day). I bought an underwater corner filter for him with low flow, but its suction cups keep coming off the side of the tank. Is there any way to make them stick more permanently? Do they sell extra ones that I could put on for better hold?

Thanks

Some suction cups are just pieces of junk, try and by new ones.

The softer they are the better i think they tend to bend more so you can get better grip.

If the suction cups don't hold at first, they never will. I'd suggest using a rock or brick to hold the filter in place (wedge it against the side of the tank, don't put the heavy object precariously on top of the filter).

Thanks everyone, I'll go buy extra suction cups and a rock today (can never be too careful

). I think part of the problem is that the cups are only on one side of the corner, maybe if they were on both sides they would push eachother into the wall.
