Anyone experience something similar? Going strictly bio-balls without having a nitrate problem?

I Switched Over to 100% Bio-Balls and Could Not Be Happier!

I've been a silent lurker on this and many other salt water aquarium forums for years, but I'm the type that spends almost every day reading discussion threads, but never signs up for an account or posts anything.

For some reason, I felt compelled to finally create an account and post something. And the only reason why is because my actual experience seems to be so different from what I've seen discussed in numerous threads and forums throughout the years.

The basic topic revolves around the use of bio-balls, and in my specific case, switching over to "100%" bio-balls. I put "100%" in quotes because, there is a caveat to this which I will explain later.

I have a 90 gallon uniquarium (70 gallon DT and 20 gallon built-in sump). My stocking is pretty heavy as I have 1 Bartlett Anthias, 1 Lawnmower Blenny, 1 Royal Gramma, 2 False Percula Clowns, 1 Yellow Pearly Jawfish, 1 Neon Goby, 1 Red Tail Tarmarin Wrasse, 1 Green Mandarin Dragonet, 1 firefish dartfish, 1 purple firefish dartfish, 1 Bengai Cardinal, 3 medium-sized hermit crabs, and 6 small-sized hermit crabs.
I'm a heavy feeder, and feed strictly frozen food (mysis, enriched brine, and bloodworms) pretty much everyday. Yes, I usually feed 2-3 cubes a day.

I have 100+ lbs. of live rock (various original sources & types: south seas base, various type of dried coral, lava rock, coral pumice, stuff I picked up from the beach, live rock from the fish store, etc.) and 100+ lbs. of live sand 3-5 inches deep.

Yes, over the past year+, I went from running 2 protein skimmers, sponge filters, 2 types of filter floss, carbon, bio-balls, and LR, basically down to just bio-balls and nothing else except the LR in my display tank.

I didn't all of a sudden remove everything, but did this over the course of a year. The first to go was reducing my protein skimmers from 2 down to 1, then to none. Then stopped using carbon and reduced my filter floss from a lot of 2 different types to essentially none (just a very small scrap remains to break the force of the splashing water coming from my external chiller). After essentially everything was gone from my sump except the bio-balls, I essentially doubled the amount of bio balls and stuffed every compartment available in my Uniquarium's sump to the max with additional bio-balls. Roughly 14 gallons worth of bio-balls.

My flow is a standard 10x with the return pump plus an additional 10x when my 2 additional power heads go on controlled by the Wavemaster controller.

So I know everyone's setup is different, but this has been the best configuration I have tinkered with so far that fits my specific situation.
I know some will say that bio-balls are good for fish only aquariums or heavy stocking and feeding, which is essentially what I have. Others will say that bio-balls are great but they are "œnitrate factories". This seems to be true in many studies, backed up by scientific theory, and practice, but in my specific case, my nitrates are strangely lower now (<5) with my current configuration compared to my previous ones. I'm not sure why, but I have some theories.

Others will say that LR is superior to bio-balls in that in can house anaerobic bacteria which can break down nitrates which bio-balls cannot, so it is best to replace the bio-balls in the sump with LR instead. Unfortunately, for me, LR in the sump wasn't as efficient at the first 2 stages of the biological filtration process as bio-balls, and plus I already had 100+ lbs. of various types of LR in my DT.

I've seen debates on "œBio-balls or LR?". It seems the debate is always either or and not both. Some say that having bioballs will out compete the aerobic bacteria from colonizing the LR thus making the LR not only less efficient with its aerobic bacteria, but also its anaerobic bacteria because the anaerobic bacteria work best when colonized in live rock under layers on aerobic bacteria.

Anyways, I'm not sure why, but that doesn't seem to be the problem in my case. I'm not sure if it is because I have so much live rock with so many various types, densities, porousness's, etc. that I was lucky enough to stumble on the magic balance?


Here is a little more info and some theories as to why this seems to work so well in my specific situation.

Although I have a so many bio balls, I more than doubled the flow in my sump and through my by doing the following: 1) removed the filter floss, carbon, pads, etc. in the pre-chambers that was doing mechanical filtration but slowing down flow. 2) removed the filter floss over the drip tray so that the water more quickly and evenly disperses over the entire drip tray. 3) running a separate pump for my chiller which has exit plumbing right above the drip tray creating even more flow.

I am guessing the high flow prevents detritus from accumulating, but is just the right amount and the high quantity of bio-balls still allows for the bacterial to remain intact.

The large amount of fine deep live sand bend houses anaerobic bacteria to complete the cycle that the bio-balls don't finish off. The so many different types of live rock of various porousness's may have the right mixture to house anaerobic bacteria too.
 
Personally I think the old school methods of reefkeeping are largely overlooked nowadays. Granted, all systems are different, but it seems that over the past 10 years, more folks have been jumping on the" cleaner is better" bandwagon. Now, it seems more and,more people have realized that cleaner isn't always better. People are dumping reactors, carbon and other things.

This is just me, but I've moved away from RO/DI units. I can remember when I used to use tap water and a chlorinated, my tanks always appeared healthier. I've had more issues in the timeframe I've used RO water and it always seemed I was chasing this problem or that. I'm not saying this is what people need do, in fact I'm sure I'm in the minority. Now, instead of using RO water or tap, I use a dual carbon reactor with matrikx blocks strictly to remove chlorine from the water. My tanks have been set up since August of last year (after a nice long break from the hobby) and I am very happy with my systems. I have zero algae issues, no Cyano, my parameters appear to stay pretty consistent and I have good color and growth from my corals. I feed my systems heavily every day too. I have good sponge growth and a thriving fuge filled with pods and the like.

I've also noticed that a lot of hobbyists are jumping on board with siporax. Imo, this is basically the same thing as bio balls.

I'm a firm believer in simplicity, a good skimmer that's rated appropriately and a good fuge on an alternating light cycle.

People want too much high tech, and not the science behind it.
 
What do you think the bioballs are doing? What is worse if you don't have them? many of the things you removed are not going to be replaced by bioballs in any quantity. Organic removal by GAC and skimming, for example, to keep the water from yellowing.

There is nothing wrong with bioballs if you have adequate export of nitrogen from the tank. But if you do have a problem with nitrate, removing the bioballs may help.

That said, I don't see a way that phosphate is being exported from the tank in the above description.
