Film/scum at surface of water?
×
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin

Hi all, I'm getting a clear film of stuff on the surface of my new planted tank every day. Sometimes it can be a tiny bit foamy but mostly just a thin film that I remove daily. There's no fish in the tank yet but it's co2 injected and has quite high lighting (1w/ltr)
Any ideas.....................

I've found that some flake food causes this. If your water parameters check out and your fish look ok, then I wouldn't worry too much about it.
Regards,
Ken.

It's a new set up and I haven't added fish yet? I've never used co2 before could that do it?

May some surface agitation might help you solve this problem ?
I hope this helps.
Regards,
Valerie

Is the tank open / have a large opening? Could be just dust settling.

I used to get it a few years ago. I think it is a harmless bacterial thing, but i could be wrong.
You can remove it by either blotting the surface of the water with kitchen towel of aggitating the surface with the filter head.
It's harmless so i wouldn't worry about it.
Smoke me a Kipper, I’ll be back for breakfast.

Pauly IMO the surface scum you mention is mostly from any plant fertilizers you are using.
1. you can add slight surface movement but you will have to increase the Co2 to compensate.
2. you can drag a paper towel over the surface to remove most of the film. Do this before Co2 on or after Co2 off so you wont effect the Co2 levels in the water.
I have this problem in a planted tank so i syphon from the surface about 1L of water. Let the spraybar agitate for a few minutes and then top up with water again.
I do this about once a week.
Hope this helps, Darren.

That sounds like it could be it Darren, I gave the tank the first time high dose last week of ferts so sounds right. Thanks, I'll try that
