Hi help needed. We have had our tropical tank running 5 months and 3 days ago put a new filter in there - Hailea - since then it had gone all cloudy. We have washed the filter and done a 50% water change (when it initally went cloudy I took out 2 buckets and then the 50% changed) but it is still not getting any better. Does anyone have any advice for us please. thanks in advance.

It's because your tank is no longer cycled due to a change in filter, you will have to recycle the tank, use the search function and search for cycling a tank on google ect.

This could well be the case, did you leave the old filter running or transfer any media from the running filter to the new filter?

Oh gosh, no our old one broke so didn't get to have a swap over as such. So do we need to take the fish out for several days to cycle the tank again? Thanks so much for the answers and I think we will use this site a lot for advice and help as we are struggling to find people in wanganui that can help - you never know thou, might be able to contact some through here

Do you have another tank that is cycled? Of the same temperature. If so and the fish you're putting in there aren't going to get eaten you can put them in there, and increase water changes. You then can cycle your new filter in the tank that it is currently in.
