what the best way to reduce No3?

[K3nneth]

Yes, ATS works. Reduced my NO3 to 0.68. Downside it consumes a lot of Ca. Dosing 80ml of Part A daily with additional separate 1 cup of Ca solution weekly, maintaining Ca at 380 and cleaning the ATS every 5 days. After switch to biopellets, my Part A reduced to 60ml daily, maintaining Ca @ 460. NO3 @ 0 to 0.25. Biopellets add a bit every monthly, but biopellets cost $100 for 1L. Both works. Cost and maintaining them are the 2 main factors here. Up to individual, what they are comfortable with. Water changes also works but for me, very tedious, unless yours is nano tank.

Sorry what is ATS?

Vinegar? I tot is vodka?

Same... All go into the carbon dosing category... needs proper dosing as excess may end up as food for bad bacteria like cyanobacteria and such...

ATS = Algae Turf Scrubber or algae scrubber.

ATS = Algae Turf Scrubber or algae scrubber.

It actually provide a place to grow algae. So all your algae will be concentrated in one area for easy removal.

There is a discussion on this ATS under general reefkeeping. U will be able to know more from there, it is very detailed.

no best way, find a way that suit your style

for carbon dosing, an over size skimmer is a must

Algae scrubber is working for me. Not much more maintenance than other methods. Just takes a little time to build one.
