That looks great!
I've had good luck with feeding the evansi fresh scallops and shrimp. Freeze and chop up.....they'll gobble down larger pieces too.

Very nice Bulent.
Love those latest shots with all the fish and coral. Looking great! Have you increased bactobalance in anticipation of a nutrient rise or will you wait to see what happens?

It is not easy to maintain large colonies in such a small tank. I have to do deforestation at least once a year in a big way. I have almost come to the end of the fragging process in the current cycle and have sold all the surplus frags. Phew. I thought I would never do it this time round as I left the frag sales too close to Christmas. As for the fish stock, as their population increases it puts more strain on my well-established nutrient balancing strategies. I am realising more and more that I need a bigger tank. I will be putting aside a proportion of the proceeds from future frag sales to save towards a new tank and equipment. Happy new year Quote:
No I have not. I predicted a spike in nutrients, especially in phosphates due to heavier than usual feeding. Today's test results confirmed my prediction. Surprisingly, NO3 remained more or less the same. It was between 5-10 ppm there days after I bought the new fish. It is 5 ppm today. However, phosphates climbed up from 0.14 mg/L to 0.25 mg/L. This is a big jump. Although coral growth continues in good speed, I can see zooxanthellae density on certain corals increasing. I am considering a number of options to deal with phosphates. NP-Bacto-Balance is not going to help reduce phosphates when they are this high. It is most effective when phosphates are below 0.1 mg/L and are on a downward trend. The options I am considering are as follows: 1) Stop NP-Bacto-Balance and switch to Elimi-NP, which is essentially polyalcohols (According to Hans Werner-Balling, Elimi-NP is much more effective in reducing phosphates than Bacto-Balance); 2) Reduce NP-Bacto-Balance and add Elimi-NP to the mix. Both Bacto-Balance and Elimi-NP are perfectly miscible; 3) Continue to use NP-Bacto-Balance and supplement it with aluminium-based phosphate remover, such as Fauna Marin Ultra-Phos; 4) Do nothing for the time being and reduce feeding to normal levels as soon as evansi start to take what every other fish take. By the way, I have restarted to dose TM Reef Actif after a two-month break. I am doing 1/2 of the recommended dose for the volume of my tank once a week. By boosting the coral growth, I am anticipating that proportionally more phosphates will be removed from the water column as they are integrated into the corals' skeleton. I think I will delay option (3) until it becomes absolutely necessary to choose it. Happy new year.

Hi Bulent, Mike from UR.
I know how you feel ref phosphate numbers going up, l use Nopox, great for No3 but not so hot on Po4. I've tried phos medias passively, that method has little effect, l always find myself filling a reactor with phosguard or something to get the Po4 in check. I see KZ have a new product, Coral Snow Plus, standard Coral Snow with a liquid phos media, 1ml to 100 liters once or twice a week is meant to keep Po4 in check. I shall order some, if it clarifies the water and looks after Po4 it's gotta be worth a go. Happy New Year Mike |

Hi Mike,
I believe that my recent high phosphate readings are not going to be a permanent issue. I do not feel comfortable with any liquid phosphates adsorbers like lanthanum chloride. That said, I would be very interested in the results of your experiment with the new Coral snow. Please keep me posted. Organic carbon dosing methods have an inherent issue with phosphates in that once nitrates are lowered to a certain level, heterotrophic bacteria struggle to consume nitrogen and phosphorus, thus leading to rises in phosphates. Bacto-Balance counters this problem because it has added phosphates in both organic and inorganic forms as well as inorganic nitrates. In my case, although phosphates are rising, nitrates remain fairly stable and are therefore not driven to really low levels. I really should increase Bacto-Balance dose, but my M. setosa reacts to a high dose, once it reaches to 2 ml per day. I have already actioned Option (2) I stated in my previous post. Instead of dosing 1.7 ml of Bacto-Balance, I have started to dose 1.2 ml of Bacto-Balance and 0.5 ml of Elimi-NP. Furthermore, I have reduced feeding to normal levels. In addition, I have re-started TM Reef Actif. As the corals start to grow faster, more phosphates will be taken out of the water column. I am also thinking about increasing the adsorption efficiency of dissolved organics by fluidising GAC instead of using it passively. If I go down this route, then I will use smaller amount of carbon and replace it more frequently. As Reef Actif will be transforming inorganic nutrients to their organic state, it makes sense to me to remove as much organics as possible and as quickly as possible. This should then go some way to address the current phosphate issue. Happy new year to you and family Mike. Bülent

Hi Bulent, I had the same issue of stable nitrates and rising phosphates and opted for option (3). Jusg a small amount of Fauna Marin Ultraphos and it has worked in keeping phosphate stable. I use just 10ml of ultraphos weekly in my 180 gallon in addition to 2ml daily of bacto balance

Bulent. Should my " localish " webshop get back to me in time to despatch the Coral Snow Plus with my original order l shall let you know how it goes.
Having no experience with liquid phos absorbers l'm not up to speed with lanthanum chloride. Are there issues with the stuff? |

I've read that the precipitate requires 10 micron socks not 100 micron. Lots of filter floss apparently also works as the precipitate is apparently sticky and sticks to the floss. Dosing into the skimmer is also supposed to work, but would defeat the purpose of dosing the Coral Snow - it's meant for pure LCl dosing only |

First few pictures of 2018.
PO4 is at a record high, 0.25 mg/L, whereas NO3 is steady, 5 ppm (as of 30th December 2017). (Acropora hyacinthus) P1110155 (Acropora yongei) P1110160 (Acropora millepora) P1110171 (Acropora gomezi) P1110175 (Acropora millepora) P1110168 (Ophiocoma sp.) IMG_3806

I have just tested NO3 and PO4.
NO3: ~5 ppm (just under)- remained the same since the last test PO4: > 0.18 mg/L (just over) down from just over 0.25 mg/L Option (2) seems to have started to produce some results within just seven days. It is pleasing that NO3 remains steady while PO4 is dropping. I dosed TM Reef Actif second time yesterday (1/2 of recommended dose). Coral growth has started to gather pace again albeit slowly. Alkalinity and calcium consumptions are going up steadily. If this combined strategy produces a downward trend in PO4, I will remove FM Ultra Phos from my shopping cart.

Corals look fantastic..
maybe eliminating the ultra phos from the cart could be done regardless..

Beautiful reef! Your Acropora are looking fantastic! It took several days and plenty of procrastination on all my projects but I just read through the whole thread and found it quite informative with plenty of stunning coral pictures. I was wondering what you think of the blue light filter you were planning on using for your iPhone? Did it work out and are you still using it?
I’ll be following along and looking forward to seeing what you choose for your tank upgrade.

The filter is OK if I take a picture of a blue coral like A. gomezi, but it changes the colour rendition of all other colours. For this reason, I am not using it anymore nor am I using my iPhone unless I must. I prefer my son's GoPro for video recording.

I went to my lfs this afternoon to buy an Acro frag. It is nothing very fancy. I was told that it may be an A. tortuosa. I think it may be an A. austera (so-called mirage tort?). What do you think?
A. tortuosa/austera(P1110194) A. tortuosa/Austera(P1110185) A. tortuosa/austera(P1110179) A. tortuosa/austera(P1110177) A. tortuosa (the mother colony) A.tortuosa 2(the mother colony)

I tested NO3 and PO4 this morning.
NO3: ~5 ppm (just under)- remained the same since the last test a week ago. PO4: > 0.14 mg/L (just over) down from just over 0.18 mg/L since the last test a week ago. Option (2) continues to produce good results. It seems that PO4 is now on a downward trend. I dosed TM Reef Actif third time yesterday (1/2 of recommended dose). Acropora sarmentosa has started to extend its polyps. Finally, I bought my 21st fish. It is P. tuka. Among a large group of tucks, it was the only one that was eating brine shrimp very eagerly. I did not hesitate to purchase it.

What do you think the cause was for it to start extending its polyps?

You have beautiful colors on your acros. I am impressed by your scientific name identification. I can name some but I’m easily mystified. If you don’t mind me asking, what are you doing for your photography. Are you using a dslr and what kind of processing are you doing. The pictures are wonderful.

I use a small digital camera (Panasonic Lumix DMC-LZ3). Its highest resolution is 2 megapixels. I use the macro setting on it form top-down photography. I have a coral viewer, which I use to take top-down pictures. Occasionally, I use my iPhone if I have to zoom into coral tissues. However, iPhone distorts blue, pink and purple colours. I hope this helps.
