Dosing advice please
 
I have been running zeo since March 2017. I have been largely successful but the tank is now showing signs of green film on the glass as well as rusty film on the rocks. The sandbed seems ok but appears with varying green or rust colored film - but it is not growing. It is just a film.

I only have two fish at the moment - a desjardini sailfin and a purple tang. I have very little clean up crew. I put in about a dozen trochus and a about 6 nessarius snails early but they seem to have died.

I have many corals which seem to be doing ok but they seem a little washed out (pale to me)
  1. Gross water volume of your complete system (incl. sump etc.) - US gallons / UK gallons / liter
    240 US gallons
  2. After rock and sand Net water volume (incl. sump etc.) - US gallons / UK gallons / liter
    212 US Gallons
  3. Intending to 2 part dose - Are you using a CaCO2 reactor or other technique
    No, but I have two part and/or kalkwasser available
  4. Are you using a PO4 reactor (how long, how long ago, etc.)?
    No
  5. Are you using Ozone?
    No
  6. Are you using UV?
    No
  7. What skimmer are you using (type, rated water volume)?
    Vertex Alpha 200
  8. What are your actual PO4 and NO3 levels
    PO4 - 0 (hannah ulr - phosporous checker)
    NO3 - 0 (hannah)
  9. 9. What are your actual Ca, Alk and Mg levels
    CA - 425 (Red Sea)
    Alk - 7.8 (Hannah)
    Mg - 1350 (Salifert)
  10. What filtration method do you use (refugium, DSB, Miracle Mud, etc.)
    Filter socks x 2
    Rollermat
    Chaeto - just started (in a panty hose sock)
  11. Type of light (Watt, color temp, how old, etc.)
    ATI LED Hybrid Powermodule - 3 LED and 8 bulbs
    4 blue+, 2 coral+, 1 actinic
  12. What corals do you keep?
    mixed reef
  13. Tissue color (light or dark)
    light pale but polyps extension seems ok
  14. How long has the tank been running
    6 months
  15. Why do you want to use the ZEOvit system
    ULNS seems successful -
  16. Any supplemental dosing (type, amount, why, etc.)
    No
  17. Live rock (how much, how old, etc.)?
    About 120 pounds ReefRock 2.0 dry/not live
  18. Any present problems?
    a. green algae light filmed on surface of glass
    b. rust colored film on rocks (not really algae) that rubs off easily
  19. Problem description (tissue loss tips, tissue loss base, diatom bloom, algae, etc.)
    Green algae and rusty colored film on rocks
  20. What test kit do you use (how old, recently switched, etc.)?
    Hannah checkers, Salifert, Red Sea (various all new)
  21. Present dosing, amounts and intervals (ZEOvit, ZEObak, ZEOfood, ZEOstart, ZEOspur2, etc.)
    .5 ml of Start Daily
    5 drops of Spongepower Daily
    5 drops Bak (Monday and Thursday
    4 drops Food (Weds)
    8 drops of SPS Amino Daily
    5 ml of LPS Amino Daily
    Pump Zeo reactor 12x daily
    25% change of Zeolite material on 10th of every other month
    100% change of ZeoCarbon on 25th of every month
  22. Other water parameters and water stability (salinity, temp, etc.)
    1.025-1.026 SG
    about 15% water change weekly with auto water changing system replacing 1.9L per day
    6 stage RODI unit - I just replaced filters - 0 TDS now but I had a TDS issue (about 38 TDS) for about 2 months and didn't realize it
    78.5 F
    PH ranges between 8.1 and 8.3
  23. Which salt brand do you use?
    HW Marine Reefer

Lets first try to reduce both amino acid products to 2 x weekly instead of daily.

ok thanks ... i will keep you updated.

I have increased flow in the tank and the rust colored film on the rocks is somewhat coming off. Time will tell.

I use Neptune WAV pumps and have them set in the 30% range on average using mostly Maverick and Malibu settings with a couple "dust off" high speed events in the mid day.

So i've been at it for a week. and there is zero discernable difference in the green skim on the glass. The rust colored film on the rocks has dissappeared entirely but that may have been from increased skimming and raising the overall power of my circ pumps.

I am of the opinion that I am overdosing Start but I just dont know. Any thoughts?

Usually for your system volume 0.8 ml 2 x daily would be the right amount however if your system is running stabile with very low nutrient concentrations you can try to reduce the dosage but I would not go lower than 0.4 ml 2 x daily. Some kind of algae and bacteria films are normal so not sure how massive they start to grow on the glass ?

So are you saying dosing should be around 1.6 ml per day?

I've been doing about .5-.8 ml per day which is less than half.

Maybe I'm allowing phosphates to get too high and green film is algae growth? I will recheck Phosphate with a different test.

Also, the green film on the glass typically only comes during the photo period. In the morning when the tank is waking, its not even visible. Then about half way through the day, its pretty obvious. If I dont clean the glass, it "clouds" the view by the end of the day - but not horribly.

If your tank is running well with the lower ZeoStart dosage and if you can keep nutrients under control with it is should be OK. You can alternatively try to dose 0.6 ml 2 x daily for example to see if that makes any difference.

Basically some kind of film on the glass is normal and as mention before it is a indicator for a working biology so I would not care much about it if it does not get more bad.

Do you dose anything else ?

No ... just those listed. I need to start adding 2-part though. So I’m trying to get the small stuff figured out ASAP.
