50,000 litre tank in a boutique hotel (Bangkok , Thailand)
Quote:
Thanks for the information . I noticed two effects regarding the addition of Lacl3 . First I notice a drop in KH so I assume that Lacl3 bind with phosphate as well as carbonate . Secondly I notice that raising magnesium is a lot harder and take more amount of magnesium chloride . Do you experience any effect on raising magnesium while dosing Lanthanum chloride ?

I had to look through our notes from when we have used LaCl. Sometimes the KH drops a little, sometimes it doesn't(at least not much enough for us to see). Perhaps our doses have been very small and the KH drop is small too. About magnesium and LaCl I don't know. I know I had trouble raising the Mg when only meassured with Salifert, but that was probably because the test wasn't that good. Nowdays I rely on the ICP tests for Mg. Not the best answers this time, sorry for that |

Thanks for your advise . Now the phosphate level is down to 0.05 ppm . KH is at 7.8 DKH but still struggling with No3 at 25 ppm . Sent from my iPhone using Tapatalk |

Yes, the nitrate usually take some time to lower. Just be careful if you use a carbon source, not to overdose and not to get too low phosphate. Adding a carbon source often lower both NO3 and PO4, but if PO4 deplete the NO3 won't go down(and corals might be a bit unhappy with zero PO4). So make sure to monitor the nutrients so that doesn't happen. Ive also seen Cyanobacteria start to grown when PO4 was depleted. Looking forward to updates on the tank! / David |

In the top left of the pic; what kind of fish is that? Some kind of parrotfish?

Impressive construction and built.
Seems like no matter how big you build, you always get to the same problems for water parameters. A professional photographer would make the tank look even more amazing. Next time in Bangkok, I sure will come to the Boutique Hotel. |

I wonder when you brought a professional to photograph your hotel, didn't he take any photos of your tank?

Not really because the aquarium was still at infancy stage . He only took a few photos of lifeless tank . Now the aquarium has matured considerably . I will post photos soon . Water parameters are getting better . Temp - average 25.5 c PH - 8.20 KH -8.5 Po4 - 0.02 No3 - 10 ppm My next target is for no3 to go down to around 2 ppm . Sent from my iPhone using Tapatalk |

I also wonder with that fish selection if sirichok plan, is for a fish only tank? Not only clams but all the soft corals and lps, I show in some photos, should have few chances to survive with those fishes, despite the massive dimensions of the tank .

All the soft corals have survived for 6 months with only occasional nipping because of the dimensions of the tank . I agreed that this would not be possible on smaller tank . The clams perished not because of the puffer but because we had problem of ammonia spike from new tank syndrome and overfeeding . We also lost a few fish in the process . Also the undulate trigger fish with bad reputation behaved extremely well and did not bother any other fish but on the contary was chased occasionally by chromis fish due to territorial issue . From my experience having both small and large aquarium , fish behave differently towards their own species and also towards corals . Once I get my parameters stable , I will start introducing sps corals . At the moment po4 is around 0.02-0.08 and no3 is around 10 ppm . I will introduce yellow coloured sps and try to maintain the colour for a few months and see what happen . Sent from my iPhone using Tapatalk |

Be very very careful feeding Caulerpa. If a fragment gets stuck between the rocks you might end up with a pest that is nearly impossible to eradicate, especially in your huge reef. I would strongly consider feeding other marine plant based foods instead. When I visit Thailand again I will definitely include your hotel in the trip! Keep up the good work!

The number of grazers definitely decreases the risk but I would be cautious.

Yes but if they only grow is cracks/crevices, then they would not pose a concern.
