First let me thank you for for previous help - it was really useful and thinks are now stable.

I now need some more advice please. I have an Eheim wet/dry filter which I only have half full of of the filter media (I cut this down worried that it might be a nitrate factory) . Recently it has started getting very noisy and after power shutdown it often leaks (unless I regularly I replace the O-rings). Is it making a significant contribution to my tank or is it not worth the hassle. Should I replace it with something else?

I have a 300litre Juwel tank with internal filter, 40kg live rock, an external Eheim cannister filter, 4 powerheads, and a Red Sea prizm skimmer

6 medium sized corals, 3 cleaner shrimp, 1 Regal Tang, 1 Yellow Tang, 2 Angels, 1 Cleaner Wrasse, 1 Goby,2 Clown, 6 snails, 3 red leg hermits

It has been running fine for 12 months though my nitrate levels are higher than I would like.

Thanks guys - this forum is such a great help.

It leaks after only 12 months? Thats no good.

I use vaseline (silicone grease) on the sealing ring to keep it leak free. The main problem I have seen with the 2227/2229 is failure of the piston. I have diabled a few of them and used them as wet/wet filters successfully.

If you are going to use a canister filter, I would use all the media. If you are worried about nitrate accumulation just clean it out every month, or as necessary. A canister filter isn't necessary on a reef tank though, so you can ditch it and rely on the live rock, internal filter and skimmer for filtration.

I am a huge fan of their canister filters, but have had more problems with that model than anything else they make.
