Default Making the switch on established tank

I've been toying with going to a zeovit system since instarted reading and researching it about 6 months ago but kept putting it off,
I have an eareefpro1200 tank that has been running for about a year and I'm worried about the effect but alas I'm not happy with just watching my tank alone I like to experiment try new things and learn as much as I can.

My tank is mainly LPS and softie at the moment I tried to dive into sps and got 4 frags of montipora and acropora about two months back unfortunately they all bleached and died ....
Meanwhile my lps softies flourish and my sebae anemone has gotten so big he's now the tank centre piece.

My tank parameters have been shakey at times due to nitrate to phosphate imbalances

Tank parameters

Salinity 1.026 stable
Temperature 25degrees Celsius stable
Ammonia 0 stable
Nitrite 0 stable
Nitrate reaches 20 then I do a water change
Phosphate 0 (undetectable) tried salifert and api kits
Calcium 440 stable
Alkalinity 9.5 (drops by 0.5 over a course of days and I dose it back again)
Ph 7.8 in morning 8 in afternoon
Magnesium 1400 ish
Strontium untested
Iodine untested

My concerns are I need to get nitrate down before i start zeovit also what's people's experience on phosphate tests I can never detect any and doesn't the bacteria and corals need trace amounts ?

Also how will and ULNS affect my softies lps and my lovely big sebae anemone?

I tried carbon dosing for a few months and biopellets to 0 effect and I'm wondering if an absence of phosphate is the culprit

Note I have 0 algae issues

Really I've seen lots of people having success with insanely high all like 10-12 I never thought 9 could be an issue?

Hi Gnarkill102

First of all I would recommend to download the dosing guide from:


It contains a lot of useful information.

The bleaching of the corals can have a lot of reasons maybe a full tank shot and a picture of your sump might be helpful in conjunction with some more details about your system:


For PO4 I personally recommend a photometer or a high sensitive test kit like Merck or Macherey Nagel but in your case it should not be the reason for the bleached corals.
