I have a Jebo 70x70cm corner tank for my Malawi's.

Problem is the stupid design of the lid makes the condensation trickle down the side of the tank, because the lid doesn't fit into the lip of the tank, but rather edges over the frame.

A stupid design which I didn't think of when buying, and only became a real problem now that it has destroyed the cabinet due to it getting wet constantly.

So I read somewhere about a condensation plate, something unheard of to me, but which I immediately figured is of course the second layer of glass slides you often find it most rectangular tanks.

Now my question is rather who would I go about making one of these things? Presumably I can't just cut a piece of perspex and plonk it down on top, because then then it wouldn't be able to breathe at all.

So I'm guessing I could drill the thing, but then again how many holes are enough, and how many are too much thus making the thing redundant?

Maybe there's another solution other than perspex?

a picture of your tank cover will help us help you better.
the easiest way to solve your dripping condensate is to put
barrier on the lid. cut strip of flexi glass and adgere it
under the lid just inside the perimeter of the tank. it will
serve as barrier and will block the flow of condensate outside.
condensate will drip back to your tank

Here's the canopy.



The Lid



And lip of which it sits on the wrong side of.



I was also thinking just adding something on the inside of the lip would make all the difference, but the first problem is getting it dry long enough to stick something there, which I guess a hair-dryer would sort out.

Benefit of a plate, would mean no more problems with the lights getting full of algae.

just cut plexiglass to fit the inside lip !!!!!!!!!!!!!

I think you okes need to draw me a picture, because I don't quite understand what you mean.

You mean like a massive sheet to cover the entire interior surface, and rest on the lower lip?

Doesn't the tank need to breathe?

yes you got it ...... no it doesnt need to breathe....but you could cut one back corner off 2" x 2"for your cables for heater .....this will be enough

I'll probably just run it up to the filter box, since the pipes need to come down there.

Cables run out at the back through a small cut out, but thinking about it the filter is still above the suggested surface, so it would still breathe via that space.

Too bad the trickles of water were so slight, because I only realised what was going on now that the cabinet is buggered from taking water, which is why I want to put this plate in now before the bloody thing gets replaced.

Hmm, I didn't think about the feeding hole at the top.

If I leave a little gap at the front for feeding purposes you think it would still cause condensation in the lid?

no it should be fine to cut a feed slot....no need to stick it down though ..just leave it loose and lift it slightly to feed ...

Yeah I don't plan on sticking it down, it's just I don't want to wear out the canopy lid by picking that up every single day either.

the way i look at your picture, the lid is overlapping the
whole tank..... and you have the air bubblers in that part
of the tank, creating a condensate effect. unless you have
big difference in room temperature to that of your water tank,
then you have condensation problem. if the temperature difference
is not that much, then what you have there is just an effect of
bursting bubbles in that area, misting the cover until all mist
drip to the side. i suggest you relocate that air stone in the
other side where you can easily wipe the dripping water.

The air bubbles come straight from the pump, basically has a feeder hose running out of the tank with a little tap.

Even when turning if off the problem persists.

Tank isn't a problem at all in summer, heater hardly ever goes on, so it's purely a case of outside temperate contrasting inside temperature.
