Diameters?

[KribensisLover1]

I’ve researched this for a long time and haven’t found great answers. I have an AC 50 and an AC 30 and I would like pre filter sponges that fit well. I have fluval edge prefilter sponges on both AC 30 and AC 50 but they fall off constantly—I’ve gone through quite a few Bc eventually they rip through the bottom as I try to get them to stay. I also have these mesh ones in the pics below which worked for a short time and then bent and fell off.

SO, I would either like the dimensions of the thinner end of the intake tubes (Bc I can only find diameter of the larger part of tubes) or a prefilter sponge recommendation that works! TY!

These are what I use for my AC 50. No issues

I've bought most of mine from Aquarium Co-op. I buy one size smaller than recommended.

Oh nice! I see how they rec certain sizes. Cool. Thank you and thank you Skrabbitskrabbit.

I use this with my AquaClear 110. They come with adapters that supposedly fit most filters.

Ahhh I see. Thank you! I’ll probably try those as well as the other options (I’ll get one for each of my three filters—the 70 I have a prefilter that works but it’s becoming really hard to get on Bc it’s mesh and bent.

It’s a great pre-filter.

If you give it a try, just be careful with the fittings/adapters. . . They are sort of brittle and will crack if you put too much pressure on them. I’ve already had to use some of the extra ones I bought.
