Great tank!
Would you mind providing details on this statement about bio pellets?
"I struggled with carbon dosing, but decided to try biopellets and as expected found them to be very detrimental to maintaining a diverse biological balance as part of the mini ecosystems we strive for...."
I added a reactor to my 120 "reef" in hopes of keeping nutrients down. The jury is out on whether they have helped or hurt. I am looking for educated opinions on how BPs have worked or not worked for others.
Thanks
sure thing:
I struggled with carbon dosing
I hope some people don't interpret this wrong as I never did carbon dose in a liquid form, I just didn't want to as a means of reducing No3 or No4.
but decided to try biopellets
bio pellets are just another form of carbon dosing, reluctantly I decided to try them.
and as expected found them to be very detrimental to maintaining a diverse biological balance as part of the mini ecosystems we strive for
Carbon dosing, including bio pellets, basically super charge bacteria cultures that are other wise population constrained. I often refer to carbon dosing as bacteria on steroids.
In an established system super charging bacteria cultures will starve out other established nutrient consumers (sponges, bivalves, feather dusters, other bacteria etc). As expected I saw significant die off in my system of these beneficial filter feeder type critters that reside in well established bio diverse live rock.
In new systems this die-off of established consumers should not be an issue as the system hasn’t had a chance to fully establish themselves to a system balance . Consider the cycles we see as a system matures; bacteria ---> algae ---> worms ---> snails etc). The systems we build will try to reach a biological balance, if we chose to offset the balance in favor of bacteria, other things suffer.
My other concern is for the health of corals that grew up in a non bio pellet environment. It would appear that for some corals if they grew up and or acclimated themselves to a non bio pellet environment, the introduction of them can take away from what they are use to consuming. There is also some speculation growing that bio pellets give off some sort of by product that may create issues to an established system (be it polymers or dead bacteria) and is why many people discharge the reactor to their skimmer for export of these by products.
