Filter Socks! My holes look funny. Trigger sump!

[CayeCaulker]

I purchased a used Trigger sump and got online to buy filter socks for it and I am more confused more than ever. These are oval!

If any of you reefers out there have this sump what do I use and where do I get them.

What's the hole diameter? Chances are it's the standard 4" filter socks - but you'd need to confirm the model and measurement. You can also use media baskets with filter floss instead.

one way they are 4" 1/4 the other 3" 1/2
