Hi All

Thought of a few things I need to ask the pro's before buying the new reef tank.

1) Does a Sump enclosed in a cabinet cause condensation, and if it does how to prevent it.

2) What is the best sump type to use ie. Sand bed, etc

3) How does every one sort out there power outages.

Just a few for now

Regards

The fact that it is in a cabinet wont cause condensation, however you will have condensation as well as salt creep, try and run a fan into the cabinet to to get the moist air out.
2) What is the best sump type to use ie. Sand bed, etc
Many options but this sump (idea stolen from Millepora) is simple and ver effective in fact you can run a hugely complex system on this

Generator? I have DC airpumps for my sump and display, need to do the generatoer thing.

You could get away just running one or 2 flow pumps and a return pump and a heater( in winter)

Hi Mustang (Hi Mekaeel/Kanga)...

I am agreeing 100% with what Kanga said.... But just in addition:
- I got my 12v power-head/pump (bilge pump) from a shop in Cape Town city centre that sells boating equipment - this works very well (the water flow of the pump is 1375 litres per hour) in keeping some water flow in the tank if the power-outage is extended (and if I am home to switch on the pump).
BUT, that said - I have noticed that my tank (and it's inhabitants) can handle power-outages fine, of up to about 6 to 8 hours..... I would start to really worry after that.... This of course depends on the size tank, the amount of water (and amount of dissolved oxygen in the water) and whether it's day or night... (night times should be better, because a lot (not all) of the inhabitants are fast asleep then and uses less oxygen when resting).....

Generators does indeed help (I have a small one in the garage for real emergencies - it would most likely cover my tank's return pumps, the two power-heads, and perhaps our fridge... :)

Otherwise I use a car battery-pack (emergency start battery pack) - which supplies 12v just fine for quite a while (a few hours in any case - running the 12v power-head....

Good Plan, Could maybe make it a little more complex with a relay of some sort, if the power goes out, other 12v motor kicks in. Will check the web for some circuits. Just a little worried playing around with 220V. I was browsing the net trying to find an example of a trickle charger for the 12V battery using solar power. This would be ideal, if the power is out the whole day, system will still run. Night time will have to worry a bit :). 1375 litres per hour is pretty good for 12 V
