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

Under Aquarium Support

Just wondering do many people put supporting material under their aquariums, and in particular, Juwel Aquariums?

Just setting a Rio 400 and I have some 9mm MDF that should fit under no problem, but the Juwel manual clear states "DO NOT place any additional
support, e.g. polystyrene, under the aquarium since this is not necessary with our aquariums."

Mainly I'm concerned by the weight a large amount of rocks would add to the aquarium. The aquarium is 400L, but due to the water displacement when adding the background, rocks, substrate etc, I reckon I'm lucky if there will be 300L (300Kg)of water. At a guess the substrate will weight in between 60kg - 100kg out of water and I haven't a clue how much the rocks will weight themselves.

So the question is - should I go against Juwels instructions and add the support? Or will the tank be able to handle the weight?

As long as there is equal weight distribution, no loose rocks and your tank is perfectly flat then in theory you could fill the whole tank with rocks and water. As long as rocks are stuck in place there is no reason for glass to crack or seals to leak.To distribute weight stack from the front to the back if you know what I mean

side view
---top

---bottom

Do the same from the sides in.

This way the side supports dont take an acute amount of weight,it is evenly distributed around the 3 sides,with the bottom taking the majority which is the safest.If you have an inch to 2 inches of substrate the weight is dispersed even more.Try to avoid having sharp rocks in direct contact with bottom glass as this is a concentrated point of pressure and will weaken that area.

if you already have a flat bed i.e. jewel stand then you wont need it. if you look closely at the under side of the tank there is a gap between the black plastic surround and the bed, so no matter what you put under the tank the gap will sill be there.

May your fish be with you:

I'm thinking of a couple of sheets of wood to go between the floating base and the actual Juwel stand. More or less have it supporting the glass base not the perimeter of the tank

just as a reply to my own post. Searching over on another forum I found a post where someone mailed Juwel about this. The response was that they bottom glass has multiple layers of support and it's possible to fill their aquariums up completely with rocks and water. So that should be that.....
