Fans are a simple way to augment the heat rejection from your tank. There are two principal means that fans can help with relative to aquarium water: 1) Blowing hot air away from the tank such as under a hood with metal halide lights and 2) Blowing air over a water surface to increase evaporation and cool the water. The first technique is obviously done near a heat source such as your lights. The second can be done in the sump or the display tank. Either can be effective for small amounts of...

Chillers are the most effective means to cool down the water in a tank. Very simple process, the aquarium water is circulated through a “mini-refrigerator” where the aquarium water passes over the cooling coils of the refrigerant. I have seen two means of implementing chillers from a plumbing point of view. 1) A secondary pump supplies water to the chiller and circulates water from the sump to the chiller and returns it to the sump. 2) The return pump has a secondary leg cut off...

Heaters Notes

Heaters… got have them but is there anything specific you need to know about them??

It seems that everything in the reef aquarium hobby has “more to the story”. This axiom holds true with heaters as well.

Let’s say that your average room temperature is 73 degrees. Let’s also assume you want to maintain your reef aquarium at 79 degrees plus or minus 1 degree. That’s a 6 degree differential… but not really. Before we go into heaters, let’s discuss a few other topics. Latent...

As with many thing in Reef Aquariums, stability is the key to success. The same is true with temperature…. Big temperature swings stress live stock.

A poll of 3reef aquarists found that most reef aquariums are kept at a temperature of 79 degrees plus/minus 1 degree. Some people keep their tanks a bit warmer or a bit cooler. The results of this poll can be found here.
