hi bro piero, thanks for reminding me to check on the chiller pump.. apparently my dad didnt heed my advice, and went on to use a 1000L/H pump for the chiller.. stubborn as always.. worse, he doesn't believe me that returning direct to tank is a better idea, and insisted on returning to sump..
anyway brought him to consult a fren, and my fren told him that its a super bad idea, den he believe..
therefore now up-ing the pump to one thats 3000L one, den return direct to tank.. now under construction..
