Lol.I was trying to figure out what a PIA was. Thought it was abbreviation for a scientific aquatic term. Could not find it in my comprehensive aquarium encyclopedia. I think I have it now.
Its a life scientific term.
Yes you can continue dosing to get to a ulns- ultra low nutrient system, thats a system 0 ammonia 0 nitrite and below 2.5 nitrate near 0 p04. At least in salt. Supposedly corals do better. But if you take nitrate readings at reefs where corals are flourishing readings are anywhere from almost nil to 20ppm some times higher. I found I had the best growth and coloration at about 15ppm. I got a large biopellet reactor and started that puppy up. Once it was running it was pretty easy to check flow output once a week and tweek if needed. Hit a nice stability about 6 weeks later and got a good routine down and just went with it. Corals did great fish were happy.
I've been thinking gow to get a better handle on nitrate mine arent terrible about 30ish by wc day. But I do 90% water changes weekly. I'd like to control nitrate and get it to say 20 ppm with biweekly changes. I'm not into doing the carbon dosing thing. But I have been trying to figure out a good way to get and support a beneficial anaerobic bacteria population without carbon dosing. Biohome supporters say their products are a perfect media that does it, but I don't want to pay that for a gimmick or I should say somthing that may work in a perfect world.
But this is a sand thread not a liqueur thead or a ulns thread. I'll stop derailing now
