160ppm nitrate suggestions?

[Doug]

My friends run denitraters from SWC. I would have to look to see if still sold there.

This was the ATS I used. Screen was app. 240sq. in. Never had any phosphate or nitrate in that tank.




The "guru" of plenums. Bob Goemans, has a site here that may help for plenums. He eventually conceded that one in the tank was a nutrient sink, that would eventually crash. Mostly because it was not easily accessible for cleaning.

I,m pretty sure he now runs a remote, so he can clean the top layers when needed. I liked Sprungs suggestion I once read of using all crushed coral substrate for it, closer to 5mm than 2mm. Allows for better diffusion, IMO. But then Goemans is suppose to the most knowledgeable on them and has written on them since they first became popular.

This is Sprungs article on the Goeman website. Not sure if in there where he suggested 5mm or it was in a Fama article.
