This is such a great forum. Thanks for all your help. I will reduce half the amount of pellets and really crack up the flow. I a pump that will do the job for sure.
I just received 1L of the new Warner Marine EcoBAK pellets to experiment on my personal 180gal display. I have been intrigued about the solid vodka dosing for some time know and with the a company like Warner Marine entering this market I just had to give it a shot. With work and summer activities my tank has taken serious neglect so effects of this product will be easily noticed and I plan to keep everything controlled for 4-5 months to evaluate this very promising product. If it works like I imagine it will this will be added to the list of common reef necessities like GFO and activated carbon.
A little about my tank, equipment, livestock and maintenance.
I have a standard AGA 180 gal with a 75 gal sump. The sump contains a DSB of about 8" but I no longer have any macro algae. I have a Reef Octopus XP3000ext on the system and only use activated carbon on occasion. The systems circulation is provided by 3 MP40 Vortechs. I will place the new Warner Marine EcoBAK Pellets in my ATB media reactor and will feed it off of my manifold that is fed off my Reeflo Dart return pump. I plan to test the water parameters tonight and place the media on line.
Here is the most recent shot of the 180gal with the LEDs on. I will get a more up-to-date shot tonight to document the results.

So far the only thing I notice with the initial use of the WM Ecobak pellets is that they tend to clump together inside the reactor. Not like the way GFO can turn to rock but more like a soft bond that is easily shifted out of place. I've read this is normal and only temporary as I have only been running them for a few days now.
^ That is exactly what it is like.
I have been using them also for a bit, and mine too are still sticky. As indicated, you can shake the reactor a bit, and they separate. However, a day or so later they are back to sticking. My algae has changed since discontinuing the vodka and exclusively using the pellets. I am using 1.5 liters on an estimated water volume of 140 gallon fowlr which is heavily stocked. My algae has completely vanished in some places and actually become greener with more growth in other places. Very strange.
Is it possible you are leaching nutrients from these areas?
That was my thought. It would explain why such growth is occuring on rock because the rock in those places absorbed phosphate. However, what is strange is that I am seeing some very green hair algae growth on my overflows and powerheads which I do not think can absorb nutrients.

It's a flow related issue. The currents hand deliver nutrients to the area of growth. It's just a symptom of not completely stripping the nutrients from the water. I'm coming to the conclusion that while the pellets help, unfortunately they are not a complete solution in many cases.

Thanks, and that makes a lot of sense. I agree that the pellets may simply be unable to handle a particular's systems nutrient load. I have an extremely stocked tank and feed enormous amounts of meaty food daily - some which definitely breaks into little pieces which rot in the system. Even with this in mind, I am running 1.5 liters which should be able to handle up to a 300 gallon water volume. As such, I do not think adding more pellets is the answer, at least, for me. Now, what I have to figure out is what to use in conjunction with the pellets to solve my nutrient problems. Although I have not been testing because it is pointless in light of the false readings I would get due to the algae, my strong suspicion is that phosphate is my real problem and not nitrate. I just put some GFO on line, but I imagine that it will become saturated fast and pretty expensive to use to reduce my phosphates. I have been looking into alternatives to reduce phosphate, particularlly lantheum, but I have not pulled the trigger on the lantheum because I have yet to find a method to dose which I am comfortable would remove the percipate and am concerned about those who report fish deaths from its dosing. I wonder i there are other waste water cleaning technologies that could be adapted to aquarium use, like the pellets, which more directly target phosphate?
