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

Have my F/E co2 system set up, it running but when the solenoid switches off, the water above the level of the bubble nozzel inside the glass drains back down the tube and into the one way valve and the section of pipe above it. Also a bit of water sucks thru the ceramic plate on the diffuser into the tube connected to it. Each time the solenoid comes on it never quite fills properly, so i cant see the bubbels, ive been topping the counter up with water each day!

Also im looking for tips on getting the 3 bubbels per second, i can get none per second, and i can get what is probably 50 per second, the knobs are so sensitive. The canister at the moment is at 10 bar and the regulator pressure is at 40 bar. Ive tried a few different combinations of bar but cant find anywhere near happy medium.

Thanks in advance Jason

Hi Jason,

The returning water into the tube can take ages to be expelled by the C02 and the water can cause the non return valve to stick. I ALWAYS use two non ret Valves a few inches apart in case one fails. Make sure you have the non ret Valve the correct way around.


Sorry Jason, just re read the post, don't think my solution is a solution.


Kev.

I know nothing about co2 systems but the pressure you're talking about seems very high.I've read that 15-20 psi is sufficient for a co2 system, which works out at 1-1.5 bar, the larger bar number of 40bar i presume is the tank pressure.Please correct me if I'm wrong.

Yes you right about that. He must be thinking about tank pressure around 40 and then 10 or less in system.

Jason when you setting up CO2 make sure you open tank only 1/4 of turn to reduce pressure on regulator. Then open regulator only 1/4 turn to reduce pressure on solenoid and needle valve. Needle valve should have less pressure as possible. From some reason some one spreads around info about fully open tank and reg but why you would do that if you have such precision piece of equipment like needle valve??
Less pressure on valve easier to regulate CO2:-)

Sorry just back to me you are using FE dont you?? Just open FE and then try to open reg only 1/4 turn and see if you be able to regulate CO2.

Needle valve it is sensitive so just be sensitive like with woman on first date:-) and dont forget you need to be patient as well as CO2 expands slowly and its expands depend on temperature. Its different on the morrning than its on the evening. Also need some time to fill tube etc when you setting up so when you do any changes give some time (10-20mins).
