Anyway what I wanted to know was do you acclimate the corals to the intense sunlight? The PAR measurements I have taken here often go BEYOND the 1500micro moles per second mark(certainly beats the crap out of any metal halide
and this even at the very bottom of the tank.
Did this not cause a problem for you? I am going to some effort to try and attentuate the light. Granted, I am closer to the equator at 23 degrees south (Johannesburg, South Africa. so no NSW for me :-( ) compared to your 40 degrees north. Anyone else at an equavalent / similar latitude that can comment?
Kind Regards,
Rafiq
Hi Rafiq
Until this day i didn't aclimate the corals, i started in March and the sun was very friendly, not to agressive like in this current month June, the Summer Solstice is in the 21 of June, 8 days to get there.
At this time i realy need to cover the tank with this shade cloth, the sun is to intense, about the 85.000 lux.
By the way, i've just both a luxmeter to pinpoint and control the rigth ammount of ligth, i'm just waiting for the his arrival:
Regards

Great thread, great pics, love to see the progress! An in ground reef pond is a great idea that I dream about here in Southern Florida (number one American destination for European tourists).
Yes, the earth can buffer (smooth out/help ease) the summer high and winter low temperatures. Some aquarists here use water coils deep in the earth to provide geothermal cooling and temepaerature stability. However, I wonder much it can buffer the display tank when it seems so shallow.
Also Vitor, you put insulation around the tank, which isolates the tank from the earth’s temperature buffering. I can see the need for some cushioning material to allow for expansion and contraction of the tank and the surrounding earth â€"œ so that the tank does not crack, but too much insulation may reduce the buffering effect. Howe did you know how much insulation to put for safety, but not too much for insulation?
What is the display tank made of?
Why isn’t the glass top removable â€"œ what benefit do you gain? Why isn’t the top simply an inch wider so that it rests across the top of the reef pond?
Of course, with so much sunlight, did you consider biological filtering with an algae refugium?
Which brings up another question â€"œ are you feeding the Tangs algae, algae flakes, dried nori seaweed or fresh macro-algae from the ocean?
Have you thought about connecting the system to a small display tank in the house? There you could shelter and observe new species?
Hi Acolin
The earth can really buffer the temp.
Yes, the tank is shallow, about 55 cm deep, it has to be, only this way i can reach all partes of the tank, in my experience at this depth the tank works very well, considering the temp/maintenance issues.
Now about the isolation, it realy helps on the tank expansion and contraction.
The importance of the insulation material is that it preserves a constant temp, exactly want we want, was you know iven the best isolation material can not maintain the temp for a long time, so what it hapens is that the temp passes throw the earth surrounding the tank, maintaining even more the temp.
"What is the display tank made of?"
The tank is all made in glass.
"Why isn’t the glass top removable?"
I can take the cover off, and reach all corners of the tank, no need for the top cover to be removable, this way i can prevente the rain to get inside.
"Why isn’t the top simply an inch wider so that it rests across the top of the reef pond?"
I didn't get this question
"did you consider biological filtering with an algae refugium?"
Yes i did, but that way i simply lose two things, my family time and the rest of my garden.
"are you feeding the Tangs algae, algae flakes, dried nori seaweed or fresh macro-algae from the ocean?"
I feed the tang all kinds of food, algae flakes, normal flakes, and dried nory.
"Have you thought about connecting the system to a small display tank in the house? There you could shelter and observe new species?"
No my friend, i don't have a inside tank and do not intend to, my time is very limited, but i wish that this new aproach to marine aquariums can bring up new ideas and new setup just like you mentioned.
Best regards

Very cool idea. I like how you didn't run a thread for months with cad drawings, etc... and just jumped right into it and made it work.
If you had to do it again is there anything you would change? Also, do you foresee this being a long term tank or do you think that you might one day go a completely different route with the same idea?
Hi Marsfrogie
Yes my friend, i certainly build a bigger sump.

awesome idea(s)
you don't worry about animals or birds looking for prey with the top open? - just a thought as a friend of mine has a terrible problem with his pond - one day you may find a seagull swimming around
Hi jnb
No, were i live the sea birds live me alone, i only have only country birds and some sparrows.

I have a question about your Acreichthys Radiatus...
Nice for aptasia control but I am curious if you've seen him nip at coral polyps at all?
Additionally where did you obtain this specimen?
Awesome tank!
Thanks!
Hi on3ofak1nd
No, i've never seen him bit any coral.
I have seen this fish in almost every fishstor where i live.

Hi Vitor,
Of course I like your project, It's really good.
To soon to take a lot of conclusions but at least we can say that is a project that works !
It was a good bet.
I'm curious about the evaporation when is totally not covered day and night, how many liters per day Vitor ?
Hi Magano
Yes, is to soon to get any conclusions.
I have about 4-5 liters evaporation.
Regards

There's a great place in Boca Raton, Florida called Gumbo Limbo that has four outdoor tanks! The first one is for nurse sharks and lemon sharks, then there's one with different native fish, two big spiny lobsters, and a giant sea turtle named Ludwig. The third tank is more like a aggressive fish tank, with large porcupine puffers, sting rays, and some eels and sea robins. The fourth tank is kinda set up like a mangrove environment, with a mated pair of snooks, some needle fish, and a juvenile barracuda. Three juvenile sea turtles also live in this tank, they were all part of a gender study and will be released into the wild once old enough. Gumbo Limbo runs a sea turtle raising programs that is helping the population of the South-East Florida area. Check it out if you're ever in Miami or Fort Lauderdale!

Very nice!!!
If i could i certainly be a volunteer,no doubt about it.

This is really cool and an energy saver too! Like someone else posted, I liked the rock better when it was not placed in an oval shape.
Any particular reason why you layed the rock out in an oval pattern?
Hi SLODEN53
Yes my friend there is a reason, this way i can see all tank from above, remember, i have a "see above" setup.
All the best
