Filter Always Slipping Down!

[Loops]

Hi everyone, Happy New Year

I have a Interpet PF1 filter, very good keeps my tank lovely.

Problem is, it's like the suckers are not strong enough to hold it, its forever lifting or slipping.

Anyone else have this trouble and any suggestions? I have looked forf bigger suckers but then they don't fit

Thanks x

We have the interpet PF2 and it slips down too. I just rested the bottom of it on the gravel and it seems fine.

Either place a rock or something below it to rest on or get some fishing line, wrap it around the top suckers and something like a matchstick on the end, loop it over the tank rim and trap it with the hood
