Default Re: new wooden hill stream tank (constr jrnl)

hi Nick,

I havenīt really more photos than I already showed. Basically the plumbing is like this:

there is a tap at left side with a RO attached. Then there is small tank with an RO water reservoir (about 20 gallons) and a rest water reservoir (about 8 gallons).
At the right hand side under the tank is a 64x20x20inch tank used as a biological filter; the 4 pumps will be placed in there delivering a 5000 gallons an hour (well, less because of the height of about 3 feet to the points where the water flows into the actual vivarium).

I have 4 points where the water flows into the viv, 2 right above the right hand side of the tank, one about 1.5 feet higher and one with a horizontal arm attached to create a broad dripping wall (well, a bit more than just dripping - make that small waterfalls).

At the left hand side I also have a pump as used for central heating systems to create a 3 ft high waterfall there.


The water refreshing system is simple. Each week I plan to run a little pump in the large reservoir for a couple of minuts, to get about 10 gallons of water to the sewer. Then I run another small pump in the RO water reservoir to add 7 gallons of RO water and then again another small pump to pump 3 gallons of rest water into the reservoir. That way I can get water hardness (is that the technical frase?) I like.

Then there is a lot of water evaporating from the tank. I just can pump RO water to get things back to the level I want.


The water level inside the vivarium will be mainly 30cm / 12inch, apart from the right hand side where I try to get water levels of 10cm and 40cm higher respectively (a bit like rapids in a small burn).

Between the pumps and the actual viv I made a connecting pipe and 4 taps (cocks?) enabling a precise regulation of the amount of water flowing at the different points into the viv.


Again, I hope I make myself clear - just ask in case I am not
