Sandra the fish rookie Posted June 16, 2021 Share Posted June 16, 2021 I added coral to ALL my tanks! I added a bit at a time not to over do it all at once. 10G got 1 pound , 20 gallon 1 pound, 40G 2 pounds and the 5G has a little less than half a pound.. I added it after water changes. the 5 G has some in the filter and a bit in the tank. I am thinking he needs more in his tank. The PH is still dropping to around 6.6 - 6.8 ish... I have hard water. 280... Should I add more? Wait??? ugh.. I do water changes every 2 weeks sometimes every 3 weeks if all is good chemistry and looks wise.
