Attn Chemistry smart people.
I have a question i cant figure out, i know its a chemical reaction of some sort but i need a bit more detailed explanation. I recently Mixed some Expert Gardener Brand all Purpose Water Soluble Plant food , with tank water for a little experiment in using it to grow Aquatic Plants(no worries no fish or snails in the tank) and i got a chemical reaction the confuses me, the temperature in the cup i was mixing it up in dropped to under 40 degrees. Any one explain why? The tank has been Dosed with K2So4, CSM+B and H2KPO4 as well. Im no Chemistry Wiz so can some explain the 30+ Degree Drop in the water temperature in the cup?
The expert Brand Contains 24% total Nitrogen broke down as follows:
3.1% ammoniacal Nitrogen
1.2% Nitrate Nitrogen
16.1% Urea Nitrogen
.09% Other water Soluble nitrogen
2.7% Water Insoluble Nitrogen
Available Phosphate (P2O5) 8.0%
Soluble Potash (K2O) 16.0%
Total Copper(copper sulfate) .07%
Total Iron (Chelated Iron) .15%
Total Zinc .06%
Before any one says it No live stock at all of any kind will be going in this tank again, i am Strictly using it as a Small Grow out tank With 4x2-liters Bottles DIY Yeast CO2, for Plants only.
So can some explain Simply and in detail what caused the Temperature Drop? Im not a Chemistry Guy so please use layman's terms if possible.
