I’ve been looking for a 7” filter cup for ages I saw that kraken were making 4” cups so I gave them a ring I spoke to a guy called Dominic I told him what I was looking for he said he would look into it I rang him back a week later he said he would have a go at it a week later he sent me this see pictures this cup is top quality I haven’t installed it in my sump yet but I know it’s going to be great no more washing filter socks😂 Dominic was very professional and incredibly helpful well done mate 👍🏻I would recommend kraken to everyone if you need anything for your hobby give them a ring...⭐️⭐️⭐️⭐️⭐️
