Not really glass, but acrylic (aka Plexiglas). But you get the idea.
The story is this: I designed my own aquarium to be made of acrylic sheets, 3/8" thick. For strange reasons that are pointless to this query (regarding additional stress to that side), I made one wall of the tank to be made of two sheets, side-by-side. So it’s actually 3/8"+3/8" = 3/4" thick on that side.
I ran the water test today, to see if there were any leaks. There is no water leaking outside tank, but I see clearly that there is some water that found a way to sneak between the two sheets of acrylic. :smack: So it is trapped between these two sheets on the side of the tank. It made some interesting little bubble patterns there as well.
Actually, it was kind of strange to watch the water get in there – by capillary action, it immediately rose above the waterline to fill all of the space between the two sheets, except where it cut itself off and made little bubbles here and there.
Question 1: Will this water, as I fear, grow algae or some strange substance, and so turn green and then brown as it all dies out, forever cursing me with an ugly brown stain on the side of my tank?
Question 2: Can you think of any way (short of ripping the whole thing apart) to get that water out? If it were a glass tank, I’d think of shoving the whole thing into the oven and baking it at a low temperature… but it’s plastic and it wouldn’t fit anyway.
I wouldn’t mind drilling one or two or four pinholes in the side of the tank to release the water (then plug them back up with silicone), but I doubt that would get all of it anyway. Simple gravity won’t pull the water out - water, with its adhesive>cohesive properties, will stick to everything other than itself (in general).
I think I’m stuck.
