What can be the cause of an oily looking film on the surface of my water? :cheers:

Un eaten food can cause it or food that is out of date. To get rid of it get some kitchen roll sheets and put them flat on the surface of the water. once they are wet pick them out and carry on doing this till the film has all gone. It will clear it up for you :)

It is also caused by lack of water of movement (which isn't really nesercary in a tropical set-up) but it could mean a filter's power has decreased if there was plenty movement beforehand.

I think there is plenty of surface movement but what can I do if I think the filter power has reduced? :gulp:

Just take the rotor and give it a rinse. That usually sorts the problem out. Just about all rotors are magnetic so there's no screws to take out or anuthing.

The film is "usually" built up protiens. Surface agitation will break it up fine, but drives off CO2. Usually if I add too much fertilizer or trace I get it, or if I wait too long between PWCs. Another trick that works to remove the film is a small cup. Dip it just below the surface to collect the film and discard. When all the film is gone, top off the water level. --------------Just had a thought, is this the planted tank? If so, when you figure out your CO2, you can use an airstone to agitate your surface agitation enough to break up the film so the filter gets it. Adjust your CO2 injection accordingly to offset any loss. I do this and it works nicely.

It could also of ment your filter needed a good clean. If this was the new tank you just recently got, I'de say, that was more than likely the case. Other than that and I dont mean to insult your inteligence, but have you checked the flow control?[

Missed that, read it but missed it until Mick pointed it out. To add to it. Sometimes I have trouble in a planted aquarium with plant debris getting sucked into the filter tube. The solution is a pre-filter on the tubes intake. This can be just a *** filter sponge cut to fit, and slide over the intake. You can see when it gets full easier then in the filters chamber,canister/or whatever. This will also reduce need for excessive media rinsing, and can save the impeller some damage. I would use a bottle brush and scrub the intake tube and impeller also, then install your prefilter. Check the pre-filter daily for blockage. That is if it wasn't a flow control brain fart.

I did yes. I've cleaned the filter a little and scrubed out the spray bar. I've moved the spray bar up a little and I've added an air stone. I'm not sure which part helped but the oily film has gone. Thanks for your advice. I think it might have been because I added the UV clarifier after the filter and with extra pipes (all of which are the correct pipes) and going through the UV clarifier I think the flow rate is reduced.

The solution is a pre-filter on the tubes intake. This can be just a *** filter sponge cut to fit,

Would this not cut the flow rate down even further?

I was pleased to find I have Physa snails in one of my tanks - apparantly these guys will happily eat the film... I'm not sure how true this is, but I certainly haven't had any since I discovered them...

Physa snails are cool, hopefully you will get t see them do the backstroke thing over the surface of the water! It's amazing...I'm sure I have seen pics somewhere...I will have to look them out for you!

Hehe, yeah - they use the surface tension to cling and walk across the underside! It's quite weird, because most snails do the cilliary thing, these guys don't have to!

:ot: Re. Physa snails, I put a link in the <a href='http://allfishforums.com/index.php?showtopic=1017' target='_blank'>thread</a> by Quirls you might find it helpful.

Back on topic. The prefilter sponge will work fine and can (if need be) be cleaned on a daily bases.(little jug of water taken from the tank, quick rinse). If none of these suggestions apply then the only other thing I can suggest is that your filter medium could be too dense. Not all of it, just the final part of whatever mediums you use. As for the UV causing a problem with impeding the flow, this could happen but not as a rule.

yes, a little, the thinking behind it is that possibly the internal sponge or mechanical filter and media get clogged pre-maturely. Also, the impeller gets more buildup and possibly damaged from a larger plant leaf. IME, Reduction is minimal unless it gets clogged with leaves.
