Well po4 is on the rise now. Thats why im planning on doing the switch now. My po4 is at .07. My nitrates are at .05 but thats the normal. It dont really get to much higher then that. Im only planning on using 200ml of pellets to begin with with 180 total water volume.
Is NOT about Bio-pellets, it is HOW to use ( # 1 will be the Reactor design then #2 is the right move of Bio-pellets) i find very few guys, that use the right way, in You tube. This is one ,good.
if you watch the bottom of the reactor, it is some kind off bang to the edge, that why i said if use round bottom, will increase the move w/out bang, you don't want to be aggressive move, have to be gentle move, then efficiency go up to the sky, by using only 1/2 they suggest.Tthat biomass , have to stay around pellets ( like white film) , any way this guy from Video , is close to the point.
Dan u right, that way i said , may need balance, i now lots of ppl. add Flourish Nitrogen , until PO4 go down to Zero , then stop add, most of reef tanks start to got Cyno ,when over dose Carbon (even Vodka etc.) for some reason most of the ppl. got sand or lots of sand got big chance of Cyno. A good way ,start 1/2 they suggest. http://www.marinedepot.com/ps_viewi...tm_medium=cse&utm_campaign=adwordsfroogle&utmAfter i try so many way to control the PO4, i come to one conclusion .
Now ,there r Pro. and Cons.
I never , got a better success to control the PO4 safe , no spikes .
My clams never grow better, sponges ,my Coco worm grow 1 1/4 in few months
Price cost low (compare GFO) i prefer http://npbiopellets.dvh-import.com/
Need to understand , how BP work.
Need 1/2 Gal. up reactor (depend size of the tank)
Need all Bio-Pellets to move nice and slow, just like dancing, NOT to be grind by reactor walls or move to slow (clog)
Never shot of the pumps (for hours)
Keep same flow all the time .
Do Not use sponge (will clog)
May need balance, start 1/2 they suggest
Need good Protein Skimmer.
Very few Reactors works well.
My best reactor, was the one w/flash light reflector in the bottom, help to move ALL Bio-Pellets , easy , melts all in same time, keep the biomass, around pellets.
