Looks awesome, How is that GYRE with a corner tank like that?

Deze twee zwemmen ondertussen ook al anderhalve week vrolijk rond:

Acanthurus Achilles & Halichoeres chrysus



Het is wel niet de beste foto (rap genomen met de iPhone)...

Sorry Guys, I was a bit to fast, I posted this to a Dutch forum as well and forgot to translate:

These two are swimming happily in my tank since the last week and a half. It is not the best picture as it was taken quickly with my iPhone...

[YoeriV]

and it is a Halichoeres Leucoxanthus instead of a Chrysus (see white belly...)

It is visible. Maybe some settings on your computer?

De ramen zijn wel niet gepoetst... De Achilles and Meliagrides still chilling:

Hi Will,

Sorry, I overlooked your question... A bit of a late response, but here it goes:

I'm having mixed feelings with the GYRE. The flow as such is great, but whatever I do, opposing sides or 90° angle, the flows do bounce at the front window causing a swirl down. You cannot see this swirl, but it hits the sand and blowing it away from the bottom in the front. I've placed some plating corals over there and hoping that once they grow they will block the curl and leaving the sand in place.

I do have to say that I'm using very fine white living sand. Maybe with a bit of heavier sand it would stay in place.

That been said, on the other places in the tank however, it gives some nice sand lines or waves or however you would like to call it.

Cheers, Yoeri

Thank you very much

fish are still doing well. The corals however are a bit stressed due to an algae plague boomed. I used to have 0 P04, but since a week it bumped up until 0,8. Changed the rowaphos and did some waterchanges to get it back straight, but it is still not a 100%.
I'm giving the system some time for now and changing the rowaphos frequently.
I guess PO4 was buffered by the rowa, but also a part in the rocks. And that now the rocks reached their capacity and the rowa is not enough.. I'm dosing only half of the suggested volume. I'll slowly bump up the rowa volume to see what it is doing and not giving the corals to much of a shock by getting it all out at once..

[YoeriV]

Well the algae plague is gone fortunately. A few water changes and filtering over activated carbon and rowaphos did the job...











cheers,
Yoeri

And a few new corals:

Euphyllia Glabrescens (golden torch)



Pink Stylophora Pistillata



a few buttons (regular and 'Lord of the Rings')

Time for a little update

The first 'pregnancy' is a fact. One of my Pseudocheilinus Hexataenia has a big belly. This will be a nice meal for the other fishies...

Since a couple of months I do have some aiptasia and it is very difficult with a large tank to get them all with a syringe. After doubting for a long time, because I know it will be fight with my surgeons, I've decided to add a rostratus to get rid of them. He's in quarantine for the moment and is well fed and eats greedy of the mysis.

For the moment, my Achilles is the boss of the main display. He's without stress and is nice and fat. I didn't touch the main display for the last couple of days to keep the stress level as low as possible (green windows and stuff like that) so I can add the rostratus this weekend. I do believe it'll be serious fight but I hope they both will get along around the middle of next week without a white spot breakout... It is also possible that the achilles will leave him alone and will have no stress as he's already the boss, but that one of my 3 Flavescens will attack the rostratus. We'll see, fingers crossed...

Cheers, Yoeri

Hi Yoeri! Amazing tank! I'd love to see some more detail of the plumbing and filtration at work.

Regarding the Gyres, I had the same issues in my 150. The sand always blew back from the front of the tank, and the gyres were noisy at above 80%. I switched back to MP40QDs and now the tank is quieter, the flow is a bit more broad and random, and the sand stays put a bit better. I will say that less fine sand will not solve that issue completely, my sand is very coarse and it still had the problem.

It looks like your tank is maturing very nicely! The fish look happy.

Keep up the good work!

Hi, thanks. You can see the filtration at work in a video at post 7 of this journal.

Regarding the sand: it stays put now since one of the monties grew and changed the swirl.

In the meantime the rostratus is in the tank. As predicted the Achilles showed who’s in charge. The yellow tangs didn’t mingle in the fight. This morning everyone knows their place and peace is back in the tank.

Cheers Yoeri

It has been a while since I've posted something on this thread. A little update:
Nothing special is happening, all fish and corals are doing well:

overview:



new occupants:

acropora sp. blue Australia


acropora sp. yellow Australia. Really fluorescent yellow like a marker.


a pair of loriculas (only one was photogenetic...), but they swim together in the tank. Zero aggression from the other occupants...


Cheers,
Yoeri

Just some pictures of the tank:

4 new fish: 2 Gramma Loreto and 2 pseudochromis fridmani (not the sharpest pin as they are still a bit spooked in my busy tank)






warm regards,

currently in quarantine: 10 Pseudoanthias Tuka.
