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

turn the heaters up . I have to do it. bring them up by a degree every day until you hit your temp. keep an eye on it when it gets warmer outside(summer) as you may need to reduce the temp again. Ambient room temp generally causes the issue

i normally don't look at what the heater says, turn it slightly/wait/raise again till you get right temperature

Have you positioned it in a way that the water being heated is flowing straight over the heater's thermostat? Could re-adjust so top (thermostat) is at angle facing into the current.

The thermostat settings are not an exact science, so a bit of trial and error is needed anyway.

and they often need a bit of time to stabilise their action.

What sort of temp is being reached in the tank?

If the thermostat lights are regularly going on and off yet the temp of the tank is nowhere what you set, then as recommended above....reset the thermostat a bit to a higher temp.

If, however, the thermostat lights tend to be constantly on, then it may be that the ambient temperature and the size of tank is too much for the heaters you have in it. If the heaters are constantly on then their lifetime will be drastically reduced. Maybe either add a 150 watt or increase the insulation around the tank (2 inch polystyrene from Woodies).

Hi matey,


As above, what temp is the tank holding at or fluctuating between, therein will lie the answer, where have you got em placed in relation to the intake. Same end or opposite end? One at each end.


I have a 300w and a 100w in my 450, they are side by side, and coped quite well with the cold, the tank is right next to a window and they still did the job.

Is your aquarium covered properly?

Also I had both of my heaters set to the same temp, if one is 1 degree less and at the other end of the tank the entire tank drops a degree before it will turn on giving it a lot of work to do and hence some fluctuation in the temprature.

use a floating/internal thermometer in your tank to show the correct temp, the stick on "digital" strips are ok as a rough guide but not as accurate. and i have always found that the temp grades on all the heaters i have are not worth their poo, to get 26 on a 500l i have 2 heaters one in the sump and one in the tank, both set to 24, and in a 100l i have a 100w set to 26.5 to get 24. put your thermometer the opposite end of the tank to the heaters and make sure they are in the flow of water so the heat is as evenly distributed as possible

20/22 degrees.......I have a eheim 2075 600ltr filter running with spary bar I think that the 300 watt heater was placed behinded the spary bar would that be the problem???? I have just placed the 2 heaters side by side and the flow is in front of them as Mark said one set at 24 and the other set at 25 !!!! I hope it does the trick
Thanks a lot

I'd set them to the same temp matey, if the one set to 25 degrees manages to work hard and keep the tank at 24.5 by staying on a lot then the other heater won't come on and the leccy usage will be actually higher. You want to heat the greatest water volume in the shortest time. Basically, if you have 2 300w heaters on together it is 600w of heating power fighting any temp drop and so addresses that temp drop very quickly and the heaters go off.

Even for me at home with the hot water, it is cheaper for us to keep the boiler hot than to constantly keep heating up a cold boiler every day or twice a day.

I think myself that if you are having no temprature issues with your set up and the heaters are not coming on a lot then, if it aint broke then don't fix it springs to mind

I only recommend it if one heater is struggling and the other is 4 5 feet away on a large tank. Though, if they are at one end a decent flow is needed to disperse the heat evenly about the tank.
