740 Gallon Plywood tank for Discus

  • We are currently upgrading MFK. thanks! -neo
I used epoxy and harder from a dutch company called polyservice.

I used Polypox GT 600 as epoxy with Polypox 355 as hardener
It's without solvents and I've already made a few backgrounds with it without any problems. The oldest ones about 8 years old by now.
The picture below is an example of my old tank which I built in 2002.

The epoxy itself is transparent so I mix it with some black pigment. Other colours are also available.
When hardened the epoxy coating is quite shiny. And stays shiny.
That's why I always use sand (terrarium sand for my plywood tank) and put a thin layer of sand on top of the epoxy (when it's still wet). That gives the background a natural look without the epoxy shine.

The tank in the picture is made in the same way but then using 0,8-1,25 mm filtersand used in swimming pools. The problem with this background was that the colour is a bit too bright so it was quite difficult to achieve a sense of depth in the tank. Later I coloured the background darker and that was a lot better.
 
wow that is great!!!
 
Sterbai corys are a neat little fish, i have 4 that sticks to each other in a 30 gallon planted tank. Nice choice, you could fit a school of 10 in there.
 
:ROFL: Cosby sweater!! :ROFL:
It's my favourite one when doing all kind of work around the house. Bought it in Norway and come to think of it....could very well be from the Cosby area ;)

Yup! they school very well indeed, and they go very well with the higher temperatures in discus tanks. I was thinking of a school of about 20 of them.

The sand is in the tank. About eight bags of 25 kgs. I will need two more I think. But this was all the shop had got.

It's a bit difficult to get it photographed properly because of the light reflections. So made some additional shots with only the HQI.

The sitting area. The HQI is placed loosely above the tank. Later on it will be hanging on a chain from the beam between the windows.

Placed some wood in the tank. It's not entirely right yet, the middle still needs some attention. But it gives an idea.

With the bright wite sand and only the HQI it looks a lot brighter than with the black bottom. It's brighter than it appears in the photograph.
 
stunning mate
is it just the photo or does it really look that deep?

with a little tweaking and planting you could make it look like its endless :headbang2just gets deeper and deeper
