Review: Very quiet - Love this filter/pump. The video has sound....but you can't really hear the pump its so quiet! I haven't got fish in yet, but I see no reason to doubt its capabilities. On the advice of another reviewer, I have gone one size up. My tank is 25l, but I got the CF1. Very happy with purchase and love the environmentally friendly filters.

## Questions & Answers

**Q: My cf3 filter arrived and it has no fittings for the back to fit to the fishtank. When i try to order replacement it only gives me the option for refu**
A: I’ve got the same problem ~ no backplate rendering the whole thing useless!

The only option I have is return it but I don’t want to go to all that trouble as I’m housebound..

**Q: Got my filter yesterday with no back parts to filter can i get these sent to me or can i buy them seprate dose anyone know? Thank you**
A: Of its brand new check the box and inside the filter itself I thought I was missing bits until I checked everything if not return it and ask for a replacement

**Q: How do i put the suction cups back on?**
A: If you look on the back you will see a hole and a thin line push it in then slide up. These keeps cups attached as they get wedged by the thinner part of the filter.

**Q: What is the black plastic with raised hole on it for please? I can't understand from instructions**
A: The holes and the black plastic is for different height to sit in the water level? Hope this helps

### ⭐⭐⭐⭐ Maybe RTM
*by R***D on 30 June 2024*

Item arrived ... but I noticed that it had a big rattle noise coming from the botom of the unit. I plugged it in and started it going, but there was almost 0 water flow through it. I thought the bottom section was sealed , but decided to actually read the manual ... actually the bottom comes off so you can clean/service the unit... and a small plastic piece had come away..I pushed it back on , plugged it in and off it went - now doing what it should be doing... I notice that some other reviewers have had the same issue... The unit is not as fast as the Marina S1 which it replaced , but it's half the cost and half the noise also... so hopefully the fish is happier with it !
