High temps, how to protect tank?
 

Environment Canada says that it will reach as high as 34 degrees (93f) on Monday and then 32 on Tuesday and wednesday.

How can I make sure that the tanks don't get too hot...besides buying a 600 dollar chiller?

Does your house have central AC?

Use it!

If not then start freezing some RO water and get ready to put it in your sump.

Only run one pump if the temp gets too hot (main sump return) turn off CL pumps and skimmer pump.

Turn off lights.

Run a fan over the sump and tank.

Keep canopy open and sump door open.

Based on the tanks in your sig you should be alright. The acrylic will hold more heat than a glass tank, be ready with the ice. If you don't have RO you can always freeze a 2L pop bottle full and just float it.

The Nano should fairly ok, leave the lights off or run for a couple hours at night and keep a fan handy.

Thanks guys. I was thinking about ice as well. I've been watching both and there is no signs of major temp fluctuations..so far so good :)

An interesting article on DIY chillers, don't know if it will work but the idea is worth looking at.

I run 100 feet of RO feed line through my sump.

Cools my sump and warms up my water before the RO unit so there is no condensation on the unit and it works more efficiently.

Total cost $8.

That will work as long as you have good city pressure.

At 100 feet of tube, you've made a conciderable pressure drop at the r/o unit inlet.

You think? Its only 1/4" tubing. From my RODI to my tank is about 50 feet, twisting and turning, and there is no pressure problem, and that is after the RODI, not before.

Easy enough to test, and the tubing is cheap!

After doesn't matter at all. (Since it just trickles out of there anyhow.)

But, there is a minimum amount of pressure required before the r/o membrane.

I just think any normal house pressure would be adequate to pump water 100 feet through 1/4" line. There must be a formula for figuring this out there, any fluid dynamics people out there? I haven't touched that subject since second year engineering!
