Vodka dosing as primary nutrient export

Recommended Posts

Hello, I'm just want your honest advanced opinion. I have a 40 gallon reef tank and I did vodka dosing on it and the Phos went down to 0ppm and nitrates are gradually coming down that started from 40ppm down to 15ppm. Now my question is I'm building a 120 gallon fish only tank with no LR and no substrate. My filtration is a 30 gallon sump with some mech media, bio ring, activated carbon, chemi  pure blue, ASM G4 PS up to 400 gal capacity. Can vodka dosing be beneficial with FO tank to remove nitrates? it worked on my 40 gallon reef. will it work on my 120 gallon since i have a 4x over protein skimmer for it?

not what you're asking but I would suggest ceramic media like Marinepur offers vs bio ring

Yes, carbon dosing will work for a FOWLR just the same.  But why no rock?  Will it be like a coral insert?

 

You must not have had much phosphate in your reef tank as carbon dosing will lower nitrate faster than phosphate.  If phosphate is 0.00, then that becomes a limiting factor in reducing nitrate.

 

ChemiPure Blue seems a little redundant when already using activated carbon.

hey Seabass, there is some boulders of rocks but not pukani or any saltwater rocks. I was planning to put a tesalatta eel and a bunch of blue damsel on that tank. so i'm just wondering it it will work.
