I am using biopellets and the NO3 is hovering at 20ppm.. Looking into wet skimming with auto top up..
1 Parapercis nebulosa (In QT)
1 Suttoni Lineata (In QT)
1 Petroscirtes breviceps (In QT)
1 Liza alata
In addition to that, my skimmer is an overkill, plenty of bacteria housings, DIY K1 media reactor, a Mudbed in my refugium...Basically that is all..
Im using K1 media as well but in a trickle tower
are you fluidising yours and how much are you using ?
