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

Jeff did you leave the heater in the tank unplugged for a half hour or so before plugging it in?
And it's a big tank wait till the morning to see how it's getting on

I just got a new heater aswell which I thought was playing up also and for a few days it was so unplugged it for ten or so minutes and bobs your uncle it seems to be OK for now.
Unplug it and see how you get on... Someone else here might have something different to do?

Sorry jeff

no thats cool il give that ago for now see what happens cheers mark,
i was just thinking what if i put the 2 of them in. the 300w in the filter box were the heater go's at 32c and the 200w down the other end at say 30c like a booster heater and then when the 300w is at 32c the 200w will stay off and just be a standby heater if the other one broke in the future, would that work?

Check the flow of your Filter, make sure it is positioned to flow to the Heater, in other words, opposite the return.

Just my opinion, but, I had a Juwel heater and it stuck, nearly cooking my Fish, Shrimp were nicely cooked but Fish survived, also, at the minima and maxima I find heaters are rarely spot on, especially the cheaper ones, I'd buy an Eheim Jaeger and you won't be disappointed.

Yep.
The thermostat settings on the heater are at best just a guide; and even if they are spot-on then they are the temperatures sensed at the thermostat and not necessarily the temperature of the water (in a combined heater/thermostat).

So if the water in a localised area, say inside the filter box containing the heater, gets to a certain temp then the heater will switch off....even if the water in the tank is not at that temp.
Then you have a thing called 'hysteresis' kicks in......this is a lag built into on/off thermostats that allows a drop in temperature somewhat below the set temperature before it kicks back in again.

The lag-time will depend not just on the thermostat but also on the power of the heater, the size of the tank, the water flow, the outside temperature, and insulation.

If the on/off style thermostats didn't have that lag built in then they would be switching on and off every second and would be of little use and soon burn out (or stick on....and have fried fish).

Hence, the idea is to allow a settling in period for a heater....use a thermometer and keep on adjusting the heater until it stabilises at the desired temp (that could take several days in some cases).

I'm not a big fan of high wattage heaters....I prefer multiple heaters of a lower wattage for larger tanks. But that is just my personal preference.

cheers ian
ive put the heater in the filter box up to max 35c around lunch time and its slowly climbing up its now at 30c on the thermometer so il have to keep an eye on it for the day,

is it a good or bad idea to put the other heater in aswell i was thinking down the other end from the box, i could hide it behind some rocks
the 300w is in the box and the 200w would be on its own down the other end or by doing this would
the weaker one 200w be doing all the work

or should i forget about the heater in the filter box and just put it in the middle of the tank flat on the bottom (which i would not like the look of i think the box idea is goog cause u dont see it)
