Pond Boss Forums AERATION Should I aerate? In a New Pond????

It won't affect the heat transfer of the loop. It will have some effect on the performance of the heat pump (HP). Temps & pressures are relative so a 10 deg rise in temp will have a relative rise in pres in the HP.
In the summer the loop is your condenser (high pres. side). A 10 deg. rise in water temp is going to have very little effect on HP performance/effenciency.
In the winter the loop is your evaporator (low pres. side). A 10 deg drop in water temp will have a greater effect on HP performance/effenciency.
Conclusion: In summer I would aerate with no reguard for the HP. In winter If your fish are happy (not too cold) the HP will be happy.

It has been repeatedly stated on this forum that people who sell fish are inclined to sell fish . The forage base should be firmly established before adding preditors. Most of the experts here advise patients. Wait till next year & your forage base will have a better chance of sustaining itself over time.
