Just doing a conversion at the moment, and I notice that my temp reading is now considerably lower than previous.
The same heater, in the same tank previously held constant readings of 25-26 celsius or 77-79 fahrenheit. For the conversion I have added
(2x T8 globes were running on their own previously) 2x 32+8 LED lights and 2 internal powerheads. There is also an Aquaclear HOB running at all times but this was running when the tank was FW.
I have also changed the substrate to coral sand and added approx 4.5 kgs of LR
Now my temp readings are around 19-21 celsius or 66-70 fahrenheit. As far as I can tell, the light on the heater is on so it is trying to heat but nothing seems to be happening? I havent changed any setting on the heater
Luckily I havent added any coral or fish etc as yet but Im pretty sure this issue has murdered my cycling process :(
Any ideas on why this is happening? Does higher water circulation mean the tank loses heat? Does the LR have something to do with dropping the temp (I dont see how it would)???
