Weight

[malky.g]

I have just bought a Trigon 190 and given that the glass bottom is unsupported i am a bit concerned about the amount of gravel and rocks that i can put onto the glass. I know that Juwel will have thought of this but it just dont feel right putting a pile of gravel, rocks and water onto a piece of unsuported glass. Also should I put anything on the glass first. Thank you for any help out there.

most of the juwel tanks have a plastic frame the supports the tank so you dont need to put anything under it iirc it tells you in the manual too

In my rio 180 theres around 30kg of substrait (gravel/plant) and 6 kg of stone/rock then the weight of the water aswell

Hi.
If you have the exact weight of your rocks, and substrate, along with details of the type of substrate you have, you could try posting in the Old World Cichlids forum (I think mubuna are old world), they should be able to help. This is because many of them will have true-to-nature biotope aquariums, with large rock displays. One of the member there will know if the weight is safe on the substrate in question.

i've just got the trigon 190, the glass goes streight onto the wooden cabinet so the weight will be dispersed through the glass and on to that.

i have loads of gravel and a large chunk of granite in mine as a centre piece

i wouldn't worry about it!

I checked my trigon 190 again and I Have a 1cm space between my glass bottom and the wooden support on the unit. ???

quote from the trigon 190 manual.........................

We strongly recommend that the appropriate JUWEL Aquarium cabinet is used. They
have a water-repellent surface and they have been made to match the dimensions and
to bear the weight of the filled aquarium. The cabinet must be positioned on a level
surface. The JUWEL Aquarium is built with a special bottom frame for security. The
aquarium should be placed directly onto the cabinet. DO NOT place any additional
support, e.g. polystyrene, under the aquarium since this is not necessary with our
aquariums.
Weight of the aquarium in kg filled with water:
218


its on page 2 of the manual

hope this clears things up for you

You can put a lot more rock in a tank than you would think. I have 130lbs of rock in a 75gal tank with no problems, and that's considered about average for mbuna tanks. Reef tanks will have even more. There was some clip floating on the web showing someone who kept adding rocks until the tank busted to find out how many it took. By the time the tank actually broke, the rock filled the entire tank with more stacked above. So unless you want rocks instead of fish, I wouldn't worry.

You can also use eggcrate, (light diffusers sold in most hardware stores, it's just a big plastic grid) it's purchased in large sheets and can easily be cut down to size. You put it on the bottom of your tank and place the rocks and substrate on top. The idea is to disperse the weight of the rocks to the whole surface instead of one point. Personally, I don't think they are necessary, but a lot of people use them.

130 pounds of rock in 75 gallon reef is a bit much but there are lots of people who do that, most only go up to 100 pounds of rock in 75 gallons.

Is the glass tempered?

i was wondering about this as well my landlord owns a rock shop/fossils, gems store and i got a few rather large, heavy pieces of petrified wood that i put in my tank. i dont seem to have any problems but i was worried about all that wieght, i made a little cave by putting two next to each other and a longer one on top so the wieght is all in one corner. i have a five pound piece of lace rock on the other side.

It's not a reef tank, it's an mbuna tank, just the standard 75gal tank.
The amount of rocks isn't at all unusual for a Malawi biotope, there are plenty of others on here that have as much rock or more than I do.
