I've just trimed my chaeto, Tear out about 1/3 of it and threw it away (Dunno if it's the right thing to do?). The remaining still covered with a little of the red dots stuff. Hope they dun get infested and overrun by the red dots again. I think most of them r a type of red hairy algae, while some is coraline cos it looked purple to me.
So does that means that u can't preset the channel for the white & blue % at different period, e.g. 1pm to 3pm 10% white, 90% blue, 3pm to 5pm 30% white 70% blue, 5pm to 9pm 50% white 50% blue and so on...? Pardon my ignorance.
