I’ve only just seen this thread. Happy New Year to you Darrel and thank you very much for all your helpful comments over the past year.
Seasons greetings to everyone else as well!
I’m having an issue with brown algae in one of my tanks and noticed that it was growing on a cleaning magnet that I keep in the tank. Magnet easily removed, cleaned and replaced. It then occurred to me that perhaps I could deliberately place something in the tank to “collect” the diatoms to...
I have diatoms in a Nano that was set up several months back. It’s a 10L low tech with a 7W LED and small internal filter. Temperature is about 25c at the moment. Photo period is about 8-9 hours. Substrate is just Unipac aquarium sand and I’m using rainwater exclusively. I do about a 50% water...
Turning off the filter is presumably to prevent beneficial bacteria being affected?
I had some green dust algae in my 10L Nano so I’ve been adding 1ml of 12% H2O2 with some fresh water once a week. The actual water volume in the tank is 7L. It was daily to start with but weekly seems to be...
Thanks for posting the link Iain. It says on that site that lack of oxygen can be part of the problem so is it worth adding an airstone? I thought that would drive off CO2 making things worse?

I think Fluval also make them so surface scum can be a problem.
The old trickle filter systems used to be fed with surface water pouring over a weir...
I used to get that quite a lot and it's not uncommon. Ehiem make a surface skimmer to connect to your intake pipe. ADA also make one. Some folks think the oil content of some fish food contributes to the problem.
