Hi Andy Kong
thanks for the comment and explanation. well it is just too hot, got to have a cooler.
For the UV may be I just keep using it for the time being, as the green algae is not that strong, hope not get any worse as I put the tank beside a bright window.
any better to put the cooler in between the filter and UV light?
I read there is a chiller call Fishcooler Nano same size as 130A , it is much better control on noise and heat, the electric bill should also better control, but not on the unit cost. Can the P20 can push this one too?
many thanks
