help with coldwater tank filter/water #1
hi all I had an 1000ef external filter but the canister got cracked and there was water all over the floor so I had to get to town quickly and buy a new filter I bought a fluval u4 and the waters gone all cloudy bad thing is I have the fish in the tank my tank is a juwel 180 its been in 24hours and has not cleared I think it may be a bacterial bloom side view of the tank

Did you put any of the sponges/media from the canister into the new U4?

If not, then you basically have an uncycled tank and are doing a "fish in " cycle. This article explains what to do to protect your fish.

Re: help with coldwater tank filter/water #4
What else was in there apart from wool? Are you also running the built in Juwel filter?

Re: help with coldwater tank filter/water #6
OK well it should have had ceramics, sponges etc too. The bacteria you had would have been in the wool/carbon, though they would struggle to hold enough long term, especially as wool needs replacing every month or so, but as they weren't reusable you're doing a fish in cycle now so check ammonia and nitrite at least daily and do a big enough water change to reduce back to 0.25ppm or less whenever they exceed that. The article I linked to in the previous post has full details of how to deal with a fish in cycle.
