Yung tubig mo sa tub mo mas mataas pa sigurado nitrate nyan sa tank mo dahil dun na nabulok corals mo. Since doon mo na pinabulok at matagal na un, im sure nag cycle na yang tub mo at nitrate na lahat yan. if you're planning to still keep that, get a test kit and measure whats the parameters of your tank and tub water. Also find a way to get Nitrate down to almost 0 by using chemicals or natural way such as macro algae. But remember, algae need strong lighting. As macro algae grows, kakainin niya yung nitrate mo then trim mo yung macro algae then give it to fellow refer or just throw it sa trash can.
pag nahihirapan ka rin financially, alisin mo na tub mo dahil laki ng water volume niya. imbis na mag waterchange ka rin dun, gamitin mo na lang yung ipang wawaterchange mo dun sa main tank mo. NO TAP WATER
