My green house for fish

[severum1]

This Sunday the rain didn't stop, so I could'nt finish covering the rear windows. But I began the structure to cover the rays tank.

I think the images speak for themselves, so no big coments are needed.

Cement to fix the structure

It's almost ready. Only a small welding failure.

It rained a lot.

All the reservoirs and tanks were filled .

2 pics from my male motoro

The water temperature was at 24ºC

Now that the weekend has passed and things are align, i'm already planning the heating system for the water from the big tank.

If it results I have plans to expand to the other smaller tanks

Well I plan to build a system for heating the water from the tank, even if it's just +1º or +2º centigrade, to minimize the electricity costs.

To do this I'll buy plumbing pipes in stainless steel, a few T's, a few curves and unions. Build a structure in H shape held against the roof of the greenhouse, by the inside, and paint it black. I will get a system which measures the temperature of the tubes and start a pump, eg start with more than 24ºC and stop over 35ºC. This sytem requires that the pumped water from the tank travels on the tube and heates it.

This is my plan. What do you think? I am thinking right and the thing should work? What is your input for this invention? what do you think about that system for measuring the temperature and trigger the bomb? Ideas?

I want to do something like this

I recomend that you have a 'Low temperature limit' for your heater as well- say 18 degrees C. If your pump turns on at 24 degrees and its a particulary cold and cloudy/dark day then your heating system may act as a chiller and cool off your tanks.

Better yet, design your control circuit to start your circulation pump once your tank temp drops to 23 degrees and run until it reaches 25 degrees. Set your low limit for 21 degrees in series with the upper temperature limit so that it will also shut off the pump if it gets too cold by dropping out the holding coil for your pump starter.

The range of two degrees either side of 23 degrees will be less stressful to your fish and allow you to store more heat in your heating coil. 35 degrees is a bit high anyway don't you think?

If you want a "high temp" limit you should probably consider setting it closer to 30 degrees IMHO

Awsome set up by the way. I've been watching this thread for quite some time now.

Thank you for your input and for your help.

I'm thinking on using the same system used in poultry incubators (i don't know if it's the correct name), chicken incubators. It's not expensive and it works, i think, for what i want. The objective is that when temperature reaches, for example, 24ºC near the ceiling the pump starts. If it lowers that temperature, the pump stops. In winter it will work like that. In Summer it will be stopped.

In saltwater is used, here in Europe (I don’t know that if in the States it’s the same system) the ATC 800, that do the same thing but it’s more expensive.

For now I’m not defining a maximum limit for the temperature. It’s a big tank and I don’t think that temperature it will be so high that a limit is needed. Only experience will tell.

I already have everything to start building my heating project.

More ideas????

im looking into a idea that might be good for you alberto.... ill let you know what i find out...

Whichever system you use make sure that the pump starts at one temperature and shuts off at a higher temperature of at least a couple of degree's other wise it will be constantly starting and stopping, causing premature burnout...
Good luck with your system!

Here I am with the developments of the weekend.

It took some fishes that were at my home, to a new home, because my things here aren't ready yet.

Here they are

And this panaque that I love.

Let's see how they adapt to the new home.
