Hey everyone, I've set up my 500 liter tank in March and since the start I've been having trouble keeping nutrients detectable, especially phosphate bottoming out a few times. I have a bunch of lps and some softies which I know need higher than detectable levels so I've been trying to feed my fish more which had been working for a while, but the last 30 days have been an absolute nightmare with how quickly and how much the nutrients have spiked, affecting my corals.
Even my "easier sps" corals started to melt even though I've had them almost from the start in perfect health. Things like caliendrum or recently introduced pavona (my test acropora obviously rtn'd after a month in my tank too). LPS look pretty happy though, extended nicely and everything.
I've been tracking my test results in Gemini so here's a chart. The "diluted" entry is where I performed a ~100 liter water change.
I'm using hanna checkers to do my tests and I verified accuracy with an icp proving they're giving good results.
When it comest to the major elements and salinity, they've been stable. Alk around 9 dkh, calcium and magnesium within range with no noticeable fluctuations.
My question is, does the tank just need time and it will stabilize/go down with water changes? I know the system is super young but it's really worrying to see such rapid changes. I have an oversized protein skimmer and a fleece roller, so I hoped I would not end up like this, but here I am.
