What suggestions do you guys have for bringing up nitrate and phosphate? I have a Reefer 300XL and it seems no matter what I do the nitrate and phosphate are extremely low, and now I'm battling dinoflagellates. Even after doubling my feeding and ceasing water changes my nitrate stayed at 0. I...

Hi, I'm battling green hair algae in my 14g tank. I started by getting phosphate levels under control and trying to maintaining levels of <0.1. Levels creep every few days, though. It's helping but not completely. According to my Red Sea test kit, the nitrates are undetectable, which seems...

How much Nitrate in an LPS and Softie dominant tank is considered too high? Mine are between 20 - 50 ppm and after spending months with Nitrate at 0, I am not sure if I want to lower it.

Hello all, I tried doing searches here as well as general Google searches but can't seem to find an answer so I thought I would just post the question to the experts. For transparency this question is for my freshwater setup but I assume will also apply to my saltwater setup once I get that...

I am doing training to learn about peritoneal dialysis, which uses diffusion across a membrane to remove waste products from people with kidney failure. Has anyone heard of using a membrane and freshly mixed saltwater to remove nitrogen/replenish trace elements this way?
