Re: How much rock in my sump? Ok so this is the theory on LR in a wet dry. Think about it. You take out the bio balls why, To help keep nitrates down correct. Then add LR to the sump for what reason. The LR is doing the same thing as the bio balls if you think about it, building up nitrates. This is the same responce I got when I did this. Eventually bought a new refugium. You should figure out a way to add some biosediment to the wet/dry with a light thats ran opposite of the tank light and some cheato. Now this will start to help reduce nitrates and start a better filter for you..... |
