Retirement and forum shutdown (17 Jan 2022)

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

A guy in work has told me that he noticed his goldfish seem to be hanging around the top of the tank somtimes gulping air.

I think I found the problem after asking some questions.
I gave him some offcuts of some plants from my tank. He had not had live plants before this. It turns out that the light on the tank is only on for a couple of hours in the evening, with that tank in a darkened room.
Am I right in assuming that the plants are taking the oxegen out of the water because they are in near darkness the majority of the day?

Remedy:
1st step is to complete a partial water change.
2nd step is to remove the plants or increase the lighting to about 10 hours a day.

The plants aren't causing the problem. In fact they should increase oxygen as plants do the opposite to animals by taking in C02 and giving off oxygen.

We would need to know some more about the tank. What size is it? How many fish and what size? What type of filtration?

You're right in terms of the first course of action being a water change. I would recommend at least 50% using water the same temperature as that in the tank and conditioned with dechlorinator.

Regards,

Ken.

Hi Ken.
Plants do release c02 at night. Thats why in a planted tank
the pH drops during the night.
I cant` see the darkness being the problem. More than likely
a water quality problem.

I'm not sure if that's true. I know if you're adding C02 to the tank, that the level goes up during lights out as the plants don't absorb it. I don't think they release C02. However, I could be wrong.

All that aside, I do agree that this is a water problem and would be interested to know what filter is being used and if the tank has been cycled.

Regards,

Ken.

That is why flowers are always taken out of hospital wards at night. Because during the night(darkness) plants will take in oxegen.
The tank is a small tank with approximatley 50 litres in it. It has an internal filter rated to the tank and the system has been running for over a year now.

what about adding an air pump to get some surface movement going?

I would doubt that the plants are the cause of the problem. Do you have a facility to test the water. Most likely it's a water problem.

Ken.

Another idea ... once the water has been tested and the parameters are showing ok, would be to add a friend to the tank and see how the new addition reacts ?
