Recommendations for filter cup please

[lacrosseboss18]

Looking to order 4 filter cups. Something that I can just reach my hand in and pull out the floss. Would rather not have to pull out the entire cup each time and flip it over.
I ordered some and they are only 3” wide and too small to get my fingers down to pull out the floss

thanks

I know Red Sea sell them, I have 2 although I’ve not been using them, I decided socks and the washing machine was easier for me personally

Yeah I’m trying the cups out. I find that I’m more likely to change the floss out because I can just leave everything under the stand and just toss the floss and put more in. No smelly socks waiting to build up to make a wash
