Those nutrients are a little lower than I'm comfortable with. But plenty of nice tanks out there with PO4 that lowI'm hitting it hard. I make a budget bottle with bacter7, af np pro, roids, fuel, and calcium carbonate. 100-150ml/day (1 or 2 feedings). 125g + 20 gal frag tank.
Then I alternate, a separate batch with biodigest bacteria, instead of bacter7, because of cost.
Both seem to benefit the tank. Not dialed in yet but nutes are still fairly low (.03po4/5ppm no3)
