Will putting a foam block to block microbubbles lead to nitrate increase? thinking of using the white 10 inch bbrick sized blocks that come with freshwater filter
i'm adding 2 small ones to help with the bubbles when i do my sump. I have 3 blocks currently in my nano and i have no nitrate problems. Juts have to clean them weekly/bi-weekly, take em out and squeeze/rinse them in RO water.
