Nitrates and Phosphates help please (1 Viewer)

Well, I spent $50 and got a Triton ICP test.

Water parameters were green up and down the board, nothing at all out of line.

Like I feared, $50 gone.

I understand the sentiment, but ruling things out is just as valuable as finding something. You know what it's not!

Exactly this. Ruling out what it isn't helps figure out the cause.

Has this become an unsolved mystery? .. I'm not seeing any more feedback and I'm just being curious. ... My tank actually never has any coralline. Even if I add in live rock with coralline, it will slowly disappear. Being the 'Blind Swordsman', I'm of course not at all meticulous about my water parameters :p. I just assume I can not keep up with my calcium to grow coralline as I rely mainly on water changes and I don't dose. To me, it is not exactly a problem as my other stuff appears to be fine and I completely cover my rocks with corals anyway. I don't have too much issue keeping easy SPS like stylophora, montipora, ... I did have a bit STN issue with the SPS like Red Dagron, Jack The Coral (?), etc. in the past (I grew them from frags to colonies then they got STN. But I did not have a chiller then, and I assumed they couldn't deal with the extreme temp fluctuation at the time with the tank temp got too high during the day with the tank in the den with big glass door). Currently, I also have a few frags of millipora and regular acropora in the tank (some have been in the tank for a year). They do show slow growth compared the monti digi which is growing in a noticeable rate.

Glad you did the test. This hobby is not cheap but an ICP test was an optional expenditure. Still doing it helped weed out many different variables.

Good on you for doing it
 
Agreed, it was good to rule out contaminants.

So we know your parameters are in the right place, nutrients are fine, now we need to look at lighting and flow - what do you have for both?
 
I have the RapidLED Onyx boxes. I have them setup on a storm controller that simulates clouds and thunderstorms, but I have lowered the intensity.

They were around 70%, then 60%, and now I have them at 49%.

Can you get your hands on a PAR meter and check to see how much light you're giving your tank?
 
Latest test today.

Ca - 490
Alk - 11.4
NO3 - 16
PO4 - .09

I'm switching from IO Reef Crystals to plain IO. Much less Alk and Ca straight from the mix.
 
BRS does a PAR meter rental ( w/ deposit).

I have one too if you're ever in the cities and want to pick it up.

Good idea. You can also buffer out some alk with acid if you want to keep using IO RC.
 
1. How high are your lights off the tank. I would raise them to 20" off the water then turn up the intensity all the way.
2. How long are the corals surviving in the tank days or weeks? If days the problem is not lights.
3. I honestly feel the use of marco rock or dead rock has caused problems for people. I dose mb7 weekly I think it helps. My tank is same size with 80g sump and 10 years old... switched to all SPS just a year ago. You may need to lower your nopox/vinegar/vodka dosing a little... I dose mine as though its only 200g.
4. You are not having any algae or slime issues are you?

I thought the purple bucket was for fish only? I tried it in the past and nuked my tank. Ive been having similar problems and decided to switch to tropic marin. There's a cost difference however,

Nope, I know a lot of folks that use regular IO for corals. Depends on what you dose manually.
 
The salt is not the problem. As long as the numbers are stable you could use reef crystals, instant ocean, red sea, tropic marin, or right now im using brightwell... ive switched them all and back and forth with very little difference.

Whatever salt you get I would try to make sure the water change doesnt affect your numbers or is as close to the numbers your running as possible.
