really??? 28celcius doesnt sound too high, I know I normally run that high and dont have any heat stress related problems....it may sound crazy but if you arent using it try using a drop or 2 of superthrive in your water.......hello...well ive found out the problem...it was really a heat stress, cant belive it really...need to get some more ventilation
the box didnt cost that much, about 100 euros for a complete setup. Ive done most of the wood work myself. New pictures will come soon
have fun
