## Questions & Answers

**Q: Are these foam blocks for the foam screen?**
A: Yes they come is packs of 2 what I do is when I do a filter clean I wash then in clear water then dip them back in the water from the tank this is important then put them back in the filter.  When I replace them I only replace one at a time. Replacement therefore on a rota system.  Once again before you put a new one in rinse it in some water from your tank prior to placing it in the filter.  Helps to keep the water at a good level. Hope this is helpful.

**Q: Will this fit the 307?**
A: Hi - I no longer use the external filter - I think I had the 206 model - it fitted it fine - I imagine the 307 would be fine as it's the same filter but just updated a bit - I would recommend asking maidenhead aquatics - they're online

**Q: Does this do the fluval 205 pump, as the box i have just received says 206/7 and 306/7**
A: No I don't think so pal the 205 is an older modal with different size smaller foams they could be trimmed I suppose

**Q: Will this fit the 407**
A: No the box says it will fit the 205 207 305 and 307.
