Difficulties / obstacles in the implementation of the aquarium

- Openings for exhaust and supply: Before the pool was delivered, I started to build the base unit. After delivery I noticed that one of the holes completely rested on the side wall and was therefore covered :( Since Y-Tong but can be processed well, the problem was sawed and ausgepfeilt after a short time :) Fortunately, I have the holes in generously chosen the plywood so that they were consistent with the Beck holes.

- Space for pool equipment: As stated above, I have laid the base cabinet in e-form. The center column I had to put something so that the T-basin, at least some space on the outside has (therefore not a classic E). With a height of 50 cm, the basin was too high. So I cut it to the left (towards the end) and front to 10 cm afterwards. The other 2 sides have left so.
Of course I could have just substantiate the Cabinet later, but that would have been too high to me at the end (especially because the main pool a 70 height). Now it can be reasonably well off work and I get anywhere easily tuned.

- Overflow shaft: Where to start? Probably a subject that was staying most :) The biggest problems I had certainly with the tightness of the duct. Since I probably have drawn too thin at first, the joints and even from the outside, the pressure in a tank 70 was too big. Again and again found himself a spot where water trickled through. So I grouted thicker and also still in what was not so easy with my thick arms. Eventually the well ended up being as good as sealed :)
