Water temperture

[dreamz]

Hi bro/sis, my Submersible Digital Thermometer when submerge in water, it read 30degree.. but when i bring it just above the water level, it drop to 28degree.. is it normal? all along i thought water temperature will be lower then the room temperature..

not exactly when your equipment used are not energy efficient.

if your equipment are of low wattage then it will not contribute much to them temperature.

but however, if your equipment uses high elec, then it will be higher then ur air temperature. the type of light u used will contribute significantly to your temperautre.

think it this way, all your equipment used on wattage are conbimed into a heater for your aquarium. then of course ur water temperature will be of higher than ur air.

china made products are known to be not energy efficient. especially on their high wattage circulation pump.

and welcome to have your first post here. do ask more questions in this forum to help urself with ur aquarium.

thx for ur fast reply.. but when i did tis is during light off, and the 2 pump i using is eheim compact 300, 300 l/h, 5W, 230V, 50Hz for my skimmer and return pump is using eheim universal 1048 pump, 600l/h, 10W.

been only using tis 2 equipment. it is a 2 x 1 x 1.5 feet tank wif ios.. any other possible reason? wanna keep coral but tank temperature may go up to 31 during sunny days..

measure ur water temperature just before lights on. thats reading will futher give us more information.

alternatively, you can use a fan to blow at the water.

try putting your ehiem pump in a small pail of water and leave it for 30mins during a windy raining day. the water confirm much warmer than the air temp.

You will be surprise how much heat the water pumps / wavemaker generates.

As a rule of thumb, any one of the above mentioned generally increases temp by 1 deg cel.

So it is not surprising that the temp is cooler at the surface then in the water.

hmmm, i guess really due to the pump.. using a min dymax W-4 series cooling fan but don seem like any help lei.. any recommended fans to introduce? thx for all the reply...
