Never saw any HA or cyano in my tank after adding the pellets.
Stinkiest skimmate my ER250 has ever produced. Now I have to clean it before it fills up or Irene complains about the smell. I also have to clean the skimmer cup in the middle of the night or it stinks up the house.
Have seen better polyp extension on my sps compared to before.
Still need to clean the glass a couple of times a week (was hoping that it would be reduced to only once a week).
Just retested the Nitrates and it used to be literally off the charts
and now its reading 10-25 ppm which is probably the lowest its ever been since the tank was first set up years ago. I have a very, very heavily stocked 210g (lots of big, hungry fish - over 10 tangs including an 8" Vlamingi and I feed alot - several times a day including full sheet of Nori and 3-4 feedings of pellets & squirt of frozen foods), so any reduction in NO3 is amazing.
Similar reduction in PO4. Was also off the charts prior to adding the pellets but now at 1ppm (yeah, still high, but way better than before) without any water changes since early June.
Originally, the 550ml did nothing probably due to a number of factors including not enough pellets for the bioload/tank size and inadequate tumbling with the poor flow and mulm clogging up the Fluidized sand bed filter. There is now 1000ml + of pellets in the container and tumbles well as long as I shake it once a week or so (still a bit of mulm production).
With the positive results, I will probably rinse out and add some more pellets to the FSB filter.
Haven't done any water changes since before the swap meet so all the reduction in nutrients must be due to the pellets.
So, to summarize:
Added more pellets mid-June
Got the pellets to tumble better (after the swap meet - cleaned out the filter and flow increased).
Nitrates dropped from off the charts to 10-25ppm (vast improvement)
Phosphates dropped from off the charts to 1ppm (vast improvement)
No water changes since early June
Very high bioload on large sps/lps heavy 210g with 75g sump
Using a ER250 skimmer
My corals have gotten used to growing up in high nutrient waters
so now they'll have to get used to med. nutrient waters.
For all the local or visiting reefers who saw the 210g reef during the swap meet, yes, my sps have fortunately adapted to less (far less) than the pristine water conditions all the books and experts claim they need. Your tanks should have better water quality so most of the frags from my tank should thrive in yours.
