So I’m thinking that even after the nitrates have been reduced through water changes they are bound to go back up when the psycho anthias resume their accustomed feeding schedule. It just doesn’t seem reasonable that even with an adjusted feeding schedule water changes alone are going to export enough nitrates unless I want to do a FOWLR.
Right now besides LR I have two fuges. One in the sump with LR and cheato, and one HOB with, I think Richard called them, Dead Mans Hands(?) . Obviously these aren’t working efficiently enough for export. There seems to be no magic bullet when it comes to nitrate reduction. I’m looking to expand the surface area for denitrification beyond what’s available in just random piles of LR in the sump and thinking about Pond Matrix that was mentioned in another thread. I’m thinking about taking out the cheato and LR, placing a series of baffles to direct the water flow thought the pond matrix before the return pump.
1) There’s only one person that chimed in with experience with Pond Matrix. Anyone else?
2) Are there any inherent dangers for the tank in pulling the already seasoned LR and cheato? The secondary fuge will still be in place and I can run an external canister filter for a month or two to seed prior to the swap.
3)What if I just fill the canister filter with Pond Matrix and run that? Will that be enough surface area to make a difference? (100gal total vol) It would make cleaning much easier.
4)Thoughts?
