Hi, I have a 55gl that is about 6 months old. I have a yellow tang, Niger trigger and a tomato clown. About 26 blue leg hermits and an emerald crab. I also have a ton of what look like feather duster tubes and little "pods
" in my sand and filter. OH and I have about 30lbs of LR
and am ordering another 30 or 40 this weekend.
My question is... I want to start adding some calcium supplements to the tank to help with the coraline growth. Do I need to take the carbon out of my HOB
filter? will the carbon remove the supplements? I have a penguin 330 with bio media in the baskets and 2 filter cartridges.
