well nothing is ever perfectly 0.0000 I run a very tight and sensative test 2 to make sure and nothing seems to be off. everything is as it should be. Everything listed is all I have but I just got in a huge 100gph skimmer with a 600gph pump. So as for skimming....Check
Carbon. well I use double the amount on my skilter and leave the penguin along by using somthing else thats white...Cant remember but I will start putting black carbon into my penguin again. I didn't at first because my nitrates were so high that it changed a color not even on the freakin tab. I thought my test was bad but it wasn't it was worse at the shop. Nitrates were off the chart so I needed to up the bacteria so I did some fiddeling around with things and replaced the black carbon with somthing that would harvest more bacteria. I guess now I can run black carbon again since my bacteria is up. My open brain is doing great it is really bulbous and loves to eat. He is doing fine along with my medusa. I will make an effort to take out the leather toxins but if I can't I will just move them to my predator tank. Oh and one more thing I have lots of flow for my tank yet I still have detrious dust on the rock when I moved things the other day. I can't seem to get enough flow where it needs to be. I made a graph and have it going in 2 large circles that are overlapping almost like a figure eight. I used cubes for supliments the last week or so and things seem fine but I will start liquid sups. as soon as I can afford it. Thanks for all the help anymore ideas please post.
