Vortech and acrylic tanks

[triggerfish1976]

I am looking for feedback from anyone is using vortechs on acrylic tanks.
I am mainly trying to find out the following:

Heat problems: Has there been any problems with the tank associated with the excess heat given off by the driver? Any temp. increases or negative effects on the acrylic itself?

Scratching: Does your vortech scratch up the acrylic?

they do get pretty warm, although I dont think it should affect the acrylic

man they run at 150 degrees.. ouch....

I read that thread already and it appears that there isn't any real long term data on what the extreme heat will do to acrylic over time since they are a fairly new product.
My main worry is if the heat will be comprable to what metal halides can do to acrylic over time as far as expansion and contraction. I am not really worried about it causing the tank to fail but there are other negative effects that can be caused by this.

MY LFS store uses one on his 300 gallon glass display and you cannot touch it for longer than few seconds, It gets super hot

I think they all run at about 140 degrees at 100%, and yeah, thats pretty damn hot!

 

[jnarowe]

I wonder if that heat actually translates into adding heat to the water column on glass tanks?

 

[sherm71tank]

I'm sure it has to add some but most of it is dissipated into the room air (which also has an effect on tank temp). Overall I think it's minimal and for sure is better than having the motor in the tank water.

 

[jnarowe]

I'll have to do some tests and see what the temp. is on the inside of the glass.

Jnarowe you have WWD's yet?

 

[jnarowe]

got 3. 2 are working and one works but sometimes needs to be reset. Waiting on 3 more.

Your welcome to check my tank if you would like. I got back from town about 30 minutes ago and the roads a pretty bad (nobody around here can drive in the snow either). The temp has also dropped back down to 32 so I'm sure they are going to start freezing into a sheet of ice very quickly.

ok so i have a 3/4 inch acrylic tank, brand new not set up yet , should i be worried when i move all my livestock and the 2 vortechs i have running?

Check my thread:

I can only add that I've seen Jonathan's tank in person and to call that "crazing" is the understatement of the year! I use the Vortech pumps on my tank but it's glass. NO WAY would I recommend them for acrylic tanks. He has multiple other spots where they have caused only cosmetic crazing as well, which would have been enough for me to crap a brick.

Thanks for posting this.
That is just crazy
