![]() Found this interesting video on Bio Pellets from LA Fishguy. Has a cool new reactor design, a decent experiment and a good theory on why bioPellets have been problematic for some people.

![]() Creative use of a single pump to recirc and also pull from sump and put it back I like.
They mention stripping things out too fast... I wish there was an answer for people like me with algae doing just fine and levels of p04 close to or zero on a meter and nitrates the same. I can't really adjust a reactor properly when according to tests these levels are super low (they mustn't be though). |

Now having said that, it was suggested here and I've heard/read many times that you don't necessarily want your nitrates and phosphates to be zero. Various organisms need some level of these nutrients. |

![]() *Sigh* now where can i buy this reactor lol. I think i should just unplugged the reactor and let the chaeto does it job and trim it more frequently.

![]() Honestly. I've been just growing cheato and mangroves. Im maintaining 0 nitrates and very low phosphates no problem.

![]() ya, personally I think that just about all methods for reducing nitrates work. macro algaes, mangroves, bio pellets, zeovit, vodka, suger, etc, etc.. All of those methods will reduce your nutrients just fine. It really just boils down to which method suits the hobbyist. If you are reducing nitrates just fine with whatever method you've employed, yet are still having problems with corals or our tank in general, I would suggest that there is something else going on. What that "something else" could be is the greatest mystery of this hobby.

![]() I like to think of it this way.. Testable levels of anything are sort of like the level in a tank that is being emptied and filled at the same time. If the tank is being drained faster than it is filled, the level will be going down, or possibly even zero if the trend continues long enough. If it fills faster than being drained, the level will be rising, unless it rises to a point where the higher level pushes water out the drain faster and thus reaches a steady state.
A test reading is a snapshot in time of where the level is "at that moment" but to determine if there is a trend you have to take many snapshots over time and compare. So taking what we know into account (like "fish poop from time to time") we know that ammonia is produced but we never get a reading in a healthy tank because it is consumed as quickly as it is produced. The bacterial strains that consume nitrate however, take longer to establish and are less hardy than those strains which consume ammonia and nitrite. Those that consume phosphate even less hardy. I guess what I'm getting at after all this is that just because a reading is 0 doesn't mean that it's not the explanation for something. You could have a nitrate or phosphate reading of zero and yet algae is in the tank or coral growth is affected. Not saying that testing is not worth it (far from it in fact) but it can only show you so much. At some point you have to rely on your instincts and intuition as well.
