Just a quick update. I will load some new photos soon, been so busy with work and every spare moment trying to tweak the tank! I took the bio-pellet plunge too quickly after not being in the hobby since 2008 and reading some misleading info on the interwebz. I thought this was a miracle cure to no3/po4, which I could easily see it being so on a larger, heavy bioload system, but my not so heavy bioload quickly got out of balance, within just a few weeks I had a terrible outbreak of a brown stringy algae that really pissed me off.
I read hours on three different algae problems: Dinoflagellates, Lyngbya and diatoms. I really could not determine which of these issues I was having, since it was spreading so quickly and covering EVERYTHING, but the corals, it had characteristics of all 3, which was weird. I upped my snail population, which helped, but did not rid the ugliness. I finally started googling "downside to BP reactors" and BINGO.... I had never seen algae like this in years past, so I figured it had to be something new I was doing and the only thing new was the LED set up and the BP reactor. After reading the "negatives" of BP reactors, I decided to take it offline.
I immediately noticed that areas i scrubbed with a toothbrush were staying clean and after roughly a week of it being offline, I do not see any new nasty algae growing and the favia and a few other LPS were looking better. Sad thing is I read quite a bit on these BP reactors prior, but I was only getting the good side of things in ultimately keeping a LNS, maybe it was select reading, I do not know, but I am happy to state that I have a better "hands on" experience with these pellets and will use them with MUCH more caution in the future, if the need should arise. I installed it early on, because I read several posts around the webz that stated to not install one on an established system, or it could crash.... Now I see why, these things strip nitrates FAST and leave me with .04 po4 (red sea test), which i guess is just enough imbalance to cause the nuisance algae to go nuts. So, my guess is that folks who have success with them have a pretty heavy bioload of fish and feed pretty heavy, this , I assume, would in essence leave enough traces of nitrates to keep things in balance.
I'm sure everyone has had different experiences and I am by no means knocking the ability of the BP reactors, just chalking up my experience with them. So don't bash me lol. I did start with a small amount of BP and only slightly increased it after the first week, was well under the recommended dosage of BP. I purchased a reef octopus reactor and had an adjustable eheim pump dialed down to the recommended flow to keep the pellets churning / tumbling. I did not, however; add a bacteria additive,a s some folks have suggested and this may have led to the algae outbreak, I really do not know. All I know is my tank looks better now without it running and I still do not have a trace of nitrates (red sea test) and my po4 remains at .03-.05.
I am about to set up a media reactor and try out Brightwells Extrax phos, which seems to be a cheaper, cleaner, easier way to deal with po4, as opposed to GFO. Does anyone have any comments on the Brightwell X-phos?
