If you like to you can soak the material in RO water for a couple of days before using it replacing the water daily, this can prevent the brown algae after the exchange especially at the beginning. Usually this does not happen later.

Have you already measured the ZeoVit reactor flow ?

How do the corals look, with a PO4 level of 0.1 – 0.15 the tissue should really become dark.

I measured the flow in the reactor, and it is coming out to about 720 liters per hour. Is that acceptable? I can't increase it any more, but I can reduce it if needed.

The SPS coral polyps look good for the most part. They are out on most of the SPS, but they could probably be better. The brown film looks much better over the past couple of days. The corals are a little dark, but my P04 is now down to 0.11.

Should I just hold steady with current dosing, or should I change anything? I thought maybe changing the zeolite early?

I am currently dosing the following:
1.0ml ZEOstart twice a day (2.0ml total per day)
8 drops Sponge Power daily
8 drops ZEObak three times a week
16 drops Biomate twice a week

Salinity: 35.5
PH: Ranges between 7.85 and 7.95
Temp: 79 degrees F
Ammonia: 0
Nitrite: 0
Nitrate: 0

Could be 100 liters higher per hour but it might work. Lets continue dosing as follows until the next ZeoVit exchange:

0.8ml ZEOstart twice a day (1.60ml total per day)
8 drops Sponge Power every other day
8 drops ZEObak three times a week
16 drops Biomate twice a week

Please keep a eye on the PO4 level if it continues to decrease slowly.

Sounds good. I will proceed as recommended.

Things appear to be really improving on my tank. My Phosphate is down to 0.09 and the brown film almost nonexistent. I have had my coral frags two weeks now, and I am already seeing growth on the across and montipora. I am shocked how much two of the acros and the plating montipora have grown in such a short period of time. The polyps are out on most of the Arcos during the day, but not fully extended to their potential.

One strange issue is my two green montipora. They are two separate types, but they are both washed out and almost white. This is only the case with my green montipora, as the red one has very good coloration. That being said, I can still see they are growing and have polyps, they are just washed out.

Can I consider adding some additional supplements now or is it still too early? I would like to fix the green color at least.

Thanks for your time.

Have you already checked the K+ level ?

Yes my K+ is at 375. All other water parameters seem to be in order, and my phosphate is continuing to fall (now down to 0.06).

Any ideas what I can do about the green montiporas being almost colorless? I have some green and yellow acros that look great.

Would it be helpful to start slowly doing some Xtra or Amoinos? I assume I should also start raising my K+ slightly.

Thanks for the help and advise!

Which kind of carbon do you use, how much and do you run it with active or passive flow ?

I am using roughly 0.75 liters of KZ carbon with passive flow. Could that be the problem?

Carbon quantity is fine. Do the corals are growing well ?

If possible please also post a picture of the affected corals.

Yes, the corals are all growing. I will post a picture shortly.

Sorry I am not a great photographer. The green montipora is the first picture and it is really light green and washed out. That being said it is growing and has polyps but just not a good coloration. All other corals are growing and looking healthy. Again, sorry for the pics. My iPhone does not seem to like the bright light of my LEDs.

Let me know your thoughts. Thanks!

Lets try to dose 8 ml Xtra every other day for one week to see if there are any improvements. Some additional water changes might also be helpful to refresh elements in a balanced way.

If just green is affected you can also try to dose some Iron if the other two changes do not cause improvements.

Finally it also can be to much light if just that one coral is affected.

Thanks. I will try dosing the Xtra. I ordered some this afternoon. I will update with results shortly.

In looking at the tank closely this evening, I still have an ever so slight brown film on small portions of the sand bed. Is this somewhat 'normal'? I should disclose that I do not have any snails or crabs (in past tanks they seem to cause problems when they die or the crabs attack fish). Perhaps I need to get something to disturb the sand bed or I need to vacuum it every few weeks..?

I have vacuum the sand while each water change weekly. It is really difficult to keep it 100% clean. Sand moving gobies can help also star fish moving the sand additional. I would also recommend to add a couple of snails to the system.

Keep a close eye on the brown film while increasing the XTra dosage temporary.
