I have an AC 20 on it, I like to feed heavily and clean the tanks often so there is allot of waste. I do agree that is a bit much so I'll probably cut it down to twice a week
Well depending on how much you are feeding them and how many there are in the tank you probably should change the water 3+ times a week. I have ac110s with my colonies and I don't feed very heavily so I don't need to change the water very often but it seems like you very well might
Here are some pictures of the tanks I have up and running in the fish room and some close up shots of some of teh inhabitants including a picture of newley hatched siquia fry!
