redracer77 Posted January 10, 2011 Report Share Posted January 10, 2011 I cleaned my CF1200 filter on the weeekend and found a couple of weird things about it, The entire inside of the filter, baskets as well had no bio-film on it, everything rinsed clean as new. Second when I put it all back together the baskets didn't fit very well, I tried without the rubber grommets between the baskets and still didn't fit well. I had to force them together to get the filter running again. This filter is running on a 300L tank with a Fluval 405 as well Any ideas of what has happened?

blueether Posted January 10, 2011 Report Share Posted January 10, 2011 You broke it , you can post it to me as I'm sure it is of no further use to you as it is... On a serious note make sure the bottom basket is sitting correctly on the little lugs. Quote Link to comment Share on other sites More sharing options...
ryanjury Posted January 10, 2011 Report Share Posted January 10, 2011 What is biofilm? You have to push the baskets together when you put it back together to make sure that it seals that is fairly usual for these things... Just make sure that there is no media or anything in the way and that everything is on straight etc.. Quote Link to comment Share on other sites More sharing options...
smidey Posted January 10, 2011 Report Share Posted January 10, 2011 also with the baskets try rotating them, they may fit better another way. bio film?? Quote Link to comment Share on other sites More sharing options...
spoon Posted January 10, 2011 Report Share Posted January 10, 2011 must mean some slimy brown algae growth that normally coats everything Quote Link to comment Share on other sites More sharing options...
redracer77 Posted January 10, 2011 Author Report Share Posted January 10, 2011 Yeah bio-film to me is the brown slimey stuff, appears once everything has cycled. I have tried rotating baskets and even without the seals still doesn't fit together like it used to, Its like the baskets are deformed, but not sure how or why it would happen. I have had the filter for over 2 years and haven't had a problem before. I have replaced the seals already a few months ago due to the old ones deforming so much. No media in the way, I checked that a few times (just in case I had a boy look the first time). I don't want to have to buy new baskets because they are pricey compared to a whole filter.

spoon Posted January 10, 2011 Report Share Posted January 10, 2011 do the baskets sit flat on a flat surface? if they dont empty the deformed one of media and put it in boiling water to soften it and staraighten it out you will need to use the small black seals on the pipes thruogh the media baskets or the filter may not work correctly Quote Link to comment Share on other sites More sharing options...
antwan Posted January 10, 2011 Report Share Posted January 10, 2011 Mine had a bit of trouble getting back in last time so I bashed them a bit, didn't take much but works fine now Quote Link to comment Share on other sites More sharing options...

phoenix44 Posted January 10, 2011 Report Share Posted January 10, 2011 Does the 405 work fine? Quote Link to comment Share on other sites More sharing options...
smidey Posted January 10, 2011 Report Share Posted January 10, 2011 ah, if i think back i may have used a piece of sand paper to skim off the edges a fraction so they slide in better. give that a go, i am sure it will be smooth after that.

redracer77 Posted January 10, 2011 Author Report Share Posted January 10, 2011 Thanks, didn't think of boiling water. Yeah black seals are on there now, just really needed to force it all in. they still aren't sitting together properly but seems to be working ok, bashing didn't help much. I will try boiling water, then sandpaper or stanley knife if that doesn't work. Quote Link to comment Share on other sites More sharing options...
ryanjury Posted January 10, 2011 Report Share Posted January 10, 2011 I have never had any issues with the ones that I have, are you sure you have everything lined up right before forcing it? I tend to use brute force before I actually find out why it isn't working and break/bend things and make it worse.. Quote Link to comment Share on other sites More sharing options...
redracer77 Posted January 10, 2011 Author Report Share Posted January 10, 2011 Yeah pretty sure, I spent about 1/2 an hour trying to get it to work, I thought at first it wasn't lining up, but definitely out of shape somewhere, I have never had an issue with it before, it normally seems to just go together. I know it sounds odd, thats why I asked here, I know a lot of people here use them. Still confused as to what happened to the brown slimey stuff (bio-film) as well, does that mean the bacteria has died off? I haven't noticed an ammonia spike but probably wouldn't with 2 filters running. Quote Link to comment Share on other sites More sharing options...
