Under my tank

[ruffkin]

This is my filter under my tank. I hope it all work out.

Wow....looking good....the only thing I can see that may give you problems is the chiller under the tank...it puts out a lot of heat...and the water in your sump may warm some....Might be somewhat counter productive.... :)

Ron
You think I should move it from under the tank. The back is completely open.

[Doctor_Reef]

You will have to play it by ear...I have mine setting outside the stand...It does put out a lot of heat!!!!

Thanks Ron,
The temp inside the tank is at 77 I will keep an eye on it. You keep your at 80?

If you can put it behind the tank that might be fine, some people will put it underneath the tank, but then install fans to remove heat from inside the stand, but unfortunatly this adds to the sound quite a bit.

If I move it out of the tank then its going to be visible in the family room. I do not want to drain the tank and move it # inches yet to hide the chiller I may try the fan first.
Thanks :idea:

LOL, yeah... thats the thing that suck with an aquarium... once you fill it they are a pain to move.

I once moved my 75gal I drained it half way and was able to move it with the sand and live rock still in with myself and 2 friends.

But yes the fans are an easier option.

I think you are forgetting one thing, a chiller is suppose to chill water, even if it emits heat from operating, its visibly doing its job ... like you said, you have your tank temp at 77, closely monitor this and if it seems to fluctuate than do apply the fans, if not, then there is no reason to preform these extra tasks ! :thumbsup:

[maxwellwhothunk]

See the thing you are not seeing is the fact that you are unnecessarily heating the water again, so you are using extra energy and also you are overworking the chiller which will eventually lead it to its early demise...

Yes this is true...but the heat that is emitted by the chiller, "which is considerable"...will heat the water in the sump and it will take the chiller longer to get the water to the desired temp.... Without venting the chiller it will work much harder to chill.... I am wondering why the LFS or whoever sold the chiller didn't mention that....????

I keep my tank at 79…in the winter and 80 in the summer…..

[Sefu]

Never had a chiller... do they really emit that much heat ?

[maxwellwhothunk]

Yep, because when you remove heat from water, it doesn't dissapear, it has to go somewhere, which is off the back of the chiller. Also since we know that there is no such thing as a perfect system, which is the reason why a perpetual motion machine cannot be made, we can assume that the chiller is letting off at least about 50% more heat that what it is removing from the water (this is with the assumtion that the machine is 66.6% efficient therefore letting off 33.3% of heat from the work).

[Doctor_Reef]

Wow....Couldn't have said it better myself!!! :lol:

[maxwellwhothunk]

Thanks Ron! Just as a side note, most chillers on the market are probably even less efficient than that! An efficient car these days is using about 30-35% of it gas to actually get people/things places, the other 65-70% is let off as heat from the engine and friction, and once you turn on your air conditioner that efficiency drops considerably. Hybrids are a step towards more efficient power usage, since instead of breaking with friction, you are actually breaking with an alternator (basically) supplemented with breaks. So when you press on the break you are engaging the alternator which then charges a battery. This is why hybrids are less efficient on the freeway... because you break much less.

The human body is also only about 30% efficient, but that other 70% of inneficiency is what keeps us warm blooded... and therefore alive :)

[Doctor_Reef]

Then I am glad we are not so efficient!!! :lol:
