Default Hi Nitrate Help Please

Hi I need some help please I started with a zeovit system back on 27/01/2019 as a mature tank to control my nitrate and phosphate levels and promote healthy corals.

Corals are all doing a lot better but I cannot drop my nitrate levels at all and my phos has to be controlled by phosphate removers.

I have 2 tangs, 2 clown fish, 6 Cardinals, a Beta Marine, Copper Band Butterfly, Mandarin, Goby, Engineering Goby, Blenny, 2 Cleaner Shrimp, few snails etc. I feed 2 blocks Daily.

Below are tank details im estimating water volume as not full accurate way to judge, I use 1.75KG of Zeovit media changed 6 weekly and I leave 10% of old media in the reactor. I add 1ltr of active carbon monthly, Flow is 1 ltrs per 5 secs.

1. Gross water volume of your complete system - Im estimating 700Ltr
Tank is 1820mmx610mmx590mm and sump 1200mmx370mmx280mm so ive worked that to 777ltrs and knocked 77ltrs off for rock

2. as above
3. Are you using a CaCO2 reactor or other technique. NO
4. Are you using a PO4 reactor (how long, how long ago, etc.) YES ATI Phosphate Stop, all the time to keep phos down or it shoots up high.
5. Are you using Ozone. NO
6. Are you using UV. NO
7. What skimmer are you using (type, rated water volume) Bubble Magnus
8. What are your actual PO4 and NO3 levels PO4 today 0.2 Nitrate 50ppm
9. What are your actual Ca, Alk and Mg levels Ca450, Alk/Kh 7, Mag 1330
10. What filtration method do you use (refugium, DSB, Miracle Mud, etc.) Filter Sock Only
11. Type of light (Watt, color temp, how old, etc.) Radion XR15w G4 Pro x 2 and Radion XR30W G4 Pro
12. What corals do you keep - mushrooms Riccodias, Acans, bubble tip, zoas, Kenya tree Monti plate.
13. Tissue color (light or dark) Middle
14. How long has the tank been running 18 months (was a smaller setup for another year transferd to bigger setup)
15. Why do you want to use the ZEOvit system, to maintain healthy corals/tank to maintain levels.
16. Any supplemental dosing (type, amount, why, etc.)
17. Live rock (how much, how old, etc.) Hard to tell 100KG + over 2 years
18. Any present problems - Casnnot get NITRATE lower than 50ppm, and Phos needs ATI Phos Stop to bring low.
19. Problem description (tissue loss tips, tissue loss base, diatom bloom, algae, etc.) Cyno outbreak since using Zeovit, using CynoClean currently
20. What test kit do you use (how old, recently switched, etc.) Salifert and Hanna Phosphorus tester
21. Present dosing, amounts and intervals (ZEOvit, ZEObak, ZEOfood, ZEOstart, ZEOspur2, etc.)
Zeostart 1.4ml daily, Sponge Power 7 drops every other day, Zeobak 8 drops twice a week, Coral Snow once a week, Coral Snow plus once a week and Cyno Clean 14 drops daily now.

22. Other water parameters and water stability (salinity, temp, etc.) 1.026 Sal 25.6 degree C
23. Which salt brand do you use - Neo Marine from Brightwell Aquatics.

Any advise will be appreciated. Thanks Rob
