Thanks Terryz,
Temp swing is very minor in my tank maybe from 27-28.5c max. Only worry was the constant water topup guess this is not too good for my tank. Thinking of iceprobe or the dolphin mini chiller (anyone use this before? any comments? price is more affordable for a non-compressor chiller comparing to iceprobe, but not so sure about efficiency). Yup 16w T5 lighting from aquazonic for 1.5ft is in the market, is it still neccessary for LED?
Thanks. Really appreciate all these question, really help me in improving. Keep it coming
