Spraybar will lower temperature?

[daveteogh]

I installed a spraybar recently and realized that the temperature actually drops by 1-2 Deg C. Of course the spraybar has to be installed at the surface of the water to create water wave to increase contact with the surface air.

Anybody share the same findings?

I think spraybar somehow has the same, if not slightly worst effect as what a fan can provide. Agree??

Share your thoughts!

Surface agitation increased evaporation?

Yes it does increase evaporation...

[David Moses Heng]

let me try first then let you know.

[nys]

Yes! Temperature will drop about 1 deg.C. I experienced it. Water needed to be topped up every few days.

For me, I using a rainbar below the water surface. The holes were "pointed" ~5deg upward. With the flow pressure, wave created.

Oh this is what I mean as well... the spraybar holes slightly below water surface and water will be sprayed out about ~5deg upwards.

I think this is the best method to create a wave with no noise!

Most important cool the water

Will it cause CO2 to escape?

I believe CO2 might escape if we use reactor to mix the CO2 with water from the filter.

It should be fine if using diffuser in the tank I guess...

That's my 2 cents thought

Why Diffuser no have this Problem .Please explain. thanks

This is what I think... might not be accurate.

Diffuser will diffuse the CO2 into the tank water directly and thus will be mixed within a large volume of water inside the tank.

Using a reactor... CO2 will be mixed within the filter water and as it is sprayed out from the bar, there is more contact with the surface air and thus more CO2 will be lost. It depends on what reactor you are using. If it is inside the tank then I guess it should be fine. I do see people putting a reactor on the external filter side.

Both methods will lost CO2 but the amount will be different I guess.

Again... my 2 cents thought

Suppose if you direct a fan at the output from the spray bar, it might cool even better? But you have to top up water more often.

I am sure the cooling effect will be better with a fan and spraybar... this creates more contact between the water and air from the fan

But... be prepared to top up water very often! I am already topping up 500ml of water everyday depending on the temperature of the day. It works great as well as we are introducing new water into the tank.

One thing to note though is by adding water, we do not remove any waste from the tank, we still need to do water change for the benefit of the fishes & plants.

How often do you suggest to change the tank water? Weekly? bi-weekly? monthly?

Is it true that the smaller the tank size, the more often we need to change water?

Only the evaporated H2O is removed. When you top up water, nothing is new, maybe some new chlorine and chloramine + whatever is in the tapwater.
