4. Are you using a PO4 reactor NO
5. Are you using Ozone no
6. Are you using UV no
7. What skimmer are you using (h&s A150)
8. What are your actual PO4 and NO3 levels(po4 0,046 merk no3 0)
9. What are your actual ca440 kh 7 mg 1350
10. What filtration method do you use only zeovit
11. Type of light (hqi 400watt aquamedic 14000k)
12. What corals do you keep sps
13. Tissue color (light )

21. Present dosing, amounts and intervals (ZEOvit 0,6litres every 6week,)(ZEObak ZEOfood 3 drops every day for 14days every zeolite change and after 3drops twice a week and turn off skimmer for 1hour every time) ZEOstart(0,6ml daily),2drops of amminoacid highconcentrate 3 times a week
22. Other water parameters and water stability (salinity 35%o, temp 25-26 c°, )

Hi Alex, thnx. for your info & your English is fine Coral growth is multi-factorial:
1)proper & stable parameters, including Ca/Mg/Kh/Temperature. Your's are fine.
2)low nutrient waters
3)availability of essential traces in our waters--5-10% water changes per week will ensure this.
4)Intense MH lighting. I would suggest using 10K bulb & consider adding actinics supplemental lighting
5)Strong, random current in-tank & brisk tank-turnover flow
6)Please dose AAHC & Coral-Vitalizer as per the ZEOvit guide--these definitely will help growth & color in your corals.

tnx bob
i change 7% of water weekly
for the light i'm working to add 4t5 from 24watt
current in the tank:actually i use 2stream 6000 alterned every 6hours
for aahc i dose only twice for po4 if i dose more my po4 growth
tomorrow i tried to turn zeofilter 3on-3off

Alex, at your stage in ZEOvit, one does not need to cycle the zeo-filter off & on. Operate it 24/7:0 Bob
