Default Not getting great results - need advice.

Hello all,

I am running my first reef tank and it is running the zeovit system. It has been running for 4 months. I am not getting great colors from my corals, limited growth and brown dust/diatoms on the sand constantly. My phosphates are never below .06 regardless of what I do. Any advise on how I can adjust/tweak my regimen to get rid of the brown dust and increase growth and colors?

Here is the specs:
1. Gross water volume of your complete system (incl. sump etc.) - US gallons / UK gallons / liter
165gal

2. Net water volume (incl. sump etc.) - US gallons / UK gallons / liter
Display Tank is 107 gal (after subtracting overflow, rock etc)

3. Are you using a CaCO2 reactor or other technique
No

4. Are you using a PO4 reactor (how long, how long ago, etc.)
GFO reactor for about 1.5 months. I was able to reduce PO4 from .44 to .06

5. Are you using Ozone
No

6. Are you using UV
No

7. What skimmer are you using (type, rated water volume)
SCA-302 180 gal

8. What are your actual PO4 and NO3 levels
PO4 = 0.06
NO3 = 4



9. What are your actual Ca, Alk and Mg levels
Ca = 420
Alk = 10.1
Mg = 1410


10. What filtration method do you use (refugium, DSB, Miracle Mud, etc.)
Live Rock (originally dry), filter socks, skimz macro algae reactor with caeto (new), GFO and Carbon in Avast Marine Spyglass reactor, Protein Skimmer

11. Type of light (Watt, color temp, how old, etc.)
2 x Brand new AI Hydra 52 HD (LED)

12. What corals do you keep
Mixed reef, softies, LPS, NPS, SPS

13. Tissue color (light or dark)
washed out/pale coloring

14. How long has the tank been running
4 months

15. Why do you want to use the ZEOvit system
Low Nutrients, straight forward system, colorful corals, crystal clear water and landscape.

16. Any supplemental dosing (type, amount, why, etc.)
ZeoStart 1ml per day
ZeoBac 10 drops twice a week
BioMate 10 drops twice a week
ZeoFood7 10 drops twice a week
ZeoZym 1/2 tsp once a week

Coral Snow 6ml with zeo bac twice a week
Coral Vitalizer 15 drops, daily

Amino Acids Complex 6 drops once a week
Amino Acids Complex LPS 3ml once a week
Poles Xtra 6ml twice a week

Coral Colors A, B, C, D 30ml of each once a week.

Phytoplankton to feed copepods 80ml twice a week.


17. Live rock (how much, how old, etc.)
Started with dry rock. It was brand "new" from BRS; Pukani. Cycled, cured etc. I also seeded with some live rock from the LFS and put it in the sump. I want to say a total of 80 lbs?

18. Any present problems
Just what I described above

19. Problem description (tissue loss tips, tissue loss base, diatom bloom, algae, etc.)
I think this is a diatom bloom. or dino-flagellates? I don't know. Colors of corals are not impressive. They are all doing well (except an elegance coral. Its closed up and wont open much each day.)

20. What test kit do you use (how old, recently switched, etc.)
Brand new testing kits. Brand new hobby. I use salifert for MG, Red Sea for Ca, Nyos for Nitrate, Hanna for alk, Hanna for phosphate, salifert for K and I.

21. Present dosing, amounts and intervals (ZEOvit, ZEObak, ZEOfood, ZEOstart, ZEOspur2, etc.)
See #16 above

22. Other water parameters and water stability (salinity, temp, etc.)
Sainity kept at 35 (1.026 spec gravity or 53 conductivity) however you like to read it. Temp at 77.5. I noticed my Iodide/Iodate is low. I tried adding an extra 10ml of Coral Colors Blue (#4?) the last two weeks

23. Which salt brand do you use
Red Sea Coral Pro

Hi CSR1987



From your dosing plan it looks like you are overdosing most of the products, is there any special reason for it ?

Does the PO4 level increase of you remove the absorber ? Also have you had those PO4 issues since the beginning ?

The KH of your system is to high, try to slowly reduce it to ~ 7 – 7.5 and keep it there as stabile as possible. Additional please cross check the salinity of your system with a different, accurate instrument.

Can you also tell how much ZeoVit material you use in your reactor and what the flow if (measured) ?

Have you ever tested the K+ (potassium) level of your system ?

If possible please post some good coral pictures additional.

G.Alexander

According to the labels and instructions, I'm under-dosing. The system volume is 165 gals. What do you suggest?

Yes, I've had PO4 levels from the beginning and yes without GFO, PO4 rises. Although I haven't tested this in the last few weeks. Add the system is rubbing 2 now, PO4 holds steady at 0.06.

Salinity had been triple checked with Apex probe, refractometer and electronic pin point meter (all calibrated).
I'm surprised to see such a low alkalinity recommendation. I can definitely give this a try. What's the reasoning/science for this being lower than all other recommendations (usually 8-12)?

Zeovit material is 1.5 liters (bag and a half) and flow is measured at 150 - 190 gal per hour.

K is consistently at 390

Pictures of some corals, including the Elegance Coral that is having the biggest issues...

The dosing quantities are calculated based on the net water volume of the system which in your case is 107 US gallons, is that correct ? If so you need to adjust your dosage also the ZeoVit quantity and the reactor flow as soon as possible.

The KH should be kept stabile which is important. Natural seawater has a KH not higher than 8 so this is the recommended level for the system also. I have not seen any differences between 6.5 or 8, growth and coloration of the corals was the same. Higher levels will just cause issues (TN) in a nutrient poor system.

For a net water volume of 55 US gallons continue dosing as follows:

ZeoBac – 4 drops daily for the first 2 weeks, than 4 drops 2 x weekly
ZeoStart – 0.4 ml 2 x daily
SpongePower – 4 drops daily
BioMate – 8 drops 2 – 3 x weekly

Run 1 liter ZeoVit with a water flow of ~ 100 US gallons per hour.

Additional 0.2 liters carbon passively flown.

The other products you use are not necessary at this stage so I would recommend to stop dosing them including the phytoplankton.

I followed all of your suggestions. Unfortunately, several corals are dead and nothing has improved. The plate Coral is dead. One of the gorgonian is dead and the other gorgonian no longer extends its polyps. A lobo receded and died around the edges. A flower tree coral seems to have wilted. A leather coral shriveled up and rotted away. My bubble coral seems less inflated when comparing it's current size to the picture I posted a month ago.

At this point I'm afraid to do anything. My alkalinity is steady at about 7.8dkh. Nitrates at 4, phosphate at 0.08.

Any other suggestions? I would like to Addy least make the unhappy corals content again.

Also what does "(TN)" mean in your comment above about high alkalinity causing problems in poor nutrient systems?

Thanks

Sorry to hear about all the losses however this is really uncommon and the affected corals are also not really sensitive so there must be some kind of a bigger problem.

TN = tissue necrosis on SPS corals

Have you added any kind of new technical equipment like hoses, plastic, pumps etc in the last couple of weeks ?
Do you still use the full quantity of PO4 absorber ?
Which kind of carbon do you use (quantity and flow) ?

I'm using the same amount of GFO and I use 150ml of zeovit carbon in a reactor. There has been nothing new other than the changes above. Things seem stable now even though some corals look unhappy.

Have you replaced the PO4 absorber recently ?

Which kind of carbon do you use exactly, which quantity and have you had running the carbon in a reactor before starting ZeoVit already ?

I am running the same GFO for the last 25 days. I replaced the Carbon and GFO together every 30 days. I am using the zeovit brand carbon. I have always run the carbon in the reactor and zeovit I started with the tank initially in April.

However, I strongly fed the corals this week and try to make my skimmer run a little less wet, and today the coral look great. Perhaps I am skimming too strong? Not feeding enough?

If your corals are doing better with less aggressive skimming lets keep the skimmer adjusted as it is at the moment.

Additional if you run the carbon with active water flow in a reactor make sure to just use 50% of the recommended quantity which in your case is 0.2 liters.

Additional dose 4 ml XTra 2 – 3 x weekly.
