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

hi all, just wonder, can I use peace of perspex to protect bottom glass when building big rock structure?

Good thinking to protect the glass from rocke damage....I've come across some who have not been so fortunate to thing ahead.

The only problem that I could see is the possibily of having an anaerobic microbial slime layer build up between the perspex and the base of glass.
It is, however, difficult to fully predict if that would have any detrimental effect or not when the tank is fully set-up as the effect would depend upon a number of factors.

yes, I was thinking about that aswell, that will be anaerobic microbial slime layer between the perspex and the base of glass... what do you think igmillichip ? is it worth to try or not?

You're likely to get that in any tank system and in many places (eg behind those glue-to-the-side corner filtration units in fluval tanks etc).
It is a potential hazard, but if the water is in good condition and well balanced then you may find it is fine.....I just mentioned it as it is a realistic hazard.

I would, however, suggest that when you evenually come to clean it out then take normal protection for yourself (as we should all be doing really in any form of handling water)...ie don't be messing with cuts on your hands or eating your chips whilst messing with the slime on the bottom of the glass. :)

If this is for freshwater, then I would recommend not allowing your nitrates go to zero (that may sound like somethign that goes against normal aquatic logic....but there is logic in it)

I was hoping nobody would ask :)

It isn't as simple as an easy reply could show, but the anaerobic bacteria that reduce nitrates to nitrogen gas are not bad for competing for nutrients and energy.....in doing so, they out-compete anaerobic bacteria that produce hydrogen sulphide (for example). If, however, nitrate is totally removed then that leaves the anaerobic sulphur reducing bacteria to get a better grip and produce toxic hydrogen sulphide.
It's more to do with water-balance than concentrating on one particular water parameter.

To avoid any Anaerobic spots simply put the Perspex on the floor of the Tank after piping silicone on the Tank floor, first a line around the perimeter below the sheet and some lines say around 3 ins apart from the middle out, this area beneath the perspex should remain dry even if under a column of Water.

Christy, I pm'd him re Egg Crate but there is a big difference between the cost of Perspex and Egg Crate and Egg Crate isn't available everywhere so that may be a factor.

Silicone the perspex to the glass? :unsure:

You know you're addicted to fishkeeping when...you spend €200 to accomodate a €5 fish.

Silicone it to the glass, inside the tank. Otherwise any dirt/sand/gravel that gets under it would be pressed against the glass which could crack it. So ensure its sealed all around the edges aswell as several lines across side to side to reduce point loading/pressure.

would just a bed of silicone do a job?

I got two peaces of this stuff, they are 50 x 50 cm, is like squares which you can connect together. I have no idea where they use this stuff in construction, but friend got it from the site.

this is the peaces I cut of the squares

Thats a nice tank. The fireplace looks well too.
You might want to silicone some off your rocks too, to prevent crushes from rock falls aswell as cracks.
Is that the plastic stuff for wiping your feet on ? You'd be aswell to put something like that in before the sand.

@ Dar: A bed of silicone or close even would be fine.The more contact the better.
A run around the perimeter of the tank with a grid of silicone lines, place the perspex in, then another run around the edge when its in place would also do the job.
If your ever underwater in a car, you can break the glass with a key. That one point concentrates enough energy to break the glass. Similar to a stone or sand under the perspex against the glass or just having one or two lines of silicone.
