I would love to run the tank sans gfo but have experienced 4 full crashes over 20 years prior to discovering it, so I figure just plug along ULN. I don't have the growth that Tyler does, and in fact I get zero growth unless I do aggressive water changes (5 gallons per day, every day), so I think nutrients are also being stripped from mine. BUT I know there's nothing being stockpiled in the DSB or the rockwork, so the coral can just figure out how to live on light alone
This is a beautiful tank, I'm okay being envious of it
I'm not quite following you, you run the GFO to keep a relative ULNS, and the 5 gallon daily water changes are adding back nutrients you think? Or you're just keeping the corals relatively hungry by having 0 nutrients in the water column and having them rely on light only? I'm assuming this is what you mean as usually water changes are a net nutrient export... either way, the salt companies must love you... I imagine you'll be stocking up come boxing day soon
