I have been reading so much on this forum about bio pellets but now that I have implemented it I have some questions...

first my current situation and params:
after 3 weeks with bio pellets...
Cal = 470
Kh = 10.5
Mg = 1350
Po4 = .07
No3 = 20ppt

My pO4 has gone from over .4 on hanna checker to the above No3 from 120 ppt to 20ppt. I have cut back on food fish and increased water changes so unsure how much my pellets have actually done. purchased sps frags which have turned brown as I did not realize my No3 was so high. siphoned the sand which seemed to make the biggest dent.

questions:

I'm having difficulty seeing N03 reduced beyond 20 which is still high. since po4 is .07 ids this the reason no3 is not reducing. I read that you need to have po4 present to reduce no3 is this correct? if not why am I unable to reduce No3? is there anything else I can try to reduce No3?

#2 will my browned out sps color back up? once levels ha ve stabilized? all sps polyps are retracted. is there anything else that I can do in the mean time during the pellet waiting period?

#3 I read that pellets can strip your water of nutrients so feeding should be kept up but also read that you should cut back of feeding. which is true?

hopefully others can chime in and learn alongside. any advice would be appreciated. thanks

additional readings:
PH = 8.35

Temp = 80

salinity = 1.025

another question:
#4 do bio pellets somehow increase salinity? I have noticed a salinity spike to over 1.029 which was quickly corrected with water changes over time.

3 weeks isnt nearly enough time to get the full benefits of the pellets. If you have changed your feeding habits and doing more water changes, then you really dont know what the pellets have done yet. It can take up to 8 weeks for the pellets to colonize with bacteria and really start seeing results. You MUST keep feeding your tank or they will strip your tank so fast your corals will not like it, and they will starve. Just give it some more time, and keep testing to see when and how fast the n03 and p04 drop.

there is no way they could do that. You might need to calibrate your refractometer???

this is what I thought and great suggestion. I did recalibrate my ph probes and corrected the high readings... I was doing water changes at the time and was adding salt thinking the readings were good and one day salinity just spiked and could see it on the graph. might be time to replace the probe but it did recalibrate so we shall see.

absolutely... but in the mean time there are things happening that are not so great. namely with SPS... ph also spiked to 8.59 which I lowered to 8.3

The bio-pellets might just need more time to get going. I'd probably wait at least another 4 weeks before worrying much.
