How many FOWLR don't use Chiller? max temperature reading?

For me I would think 27-28 is ok. Considering dive sites in This part

of the world to have approx that temp. Pulau Tioman is 29c n is thriving.

Most shops recommend below 29c, so I feel 27-28 is safe.

Maybe u can google on Your Frenchie. Perhaps frequent WC or

trace element dosing would help her recovery in 1 mths time.

i set chiller at 28.5. believe fishes have better colouration at low temp, especially angel
