RalfP's little coral reef Jan. 2012

[@Alex_Correa]

Halide/T5 system! That was the norm back in the 90's/ early 2000's! The power of the energy for a very healthy system!

[@NetGawker]

If you ever decide to make an hour long video of your setup, I would definitely buy it. Amazing work. A true inspiration for all hobbyists.

[@SwihartPhotography]

That tank is balling out of control... So awesome. I would throw my television in the trash if I had that in my living room.

[@Ok-551]

Saw Ralph’s thread on RC 10 yrs ago and it is truly inspirational. A work of art.

[@DanielMigneault]

Some pretend to have a piece of the ocean in there living room, you don't...you have it! really a piece of art.

[@urbanrat84]

I've seen a lot of tanks over the years and this would have to be my Number 1 - it appeals to me in every way. And that flow could not be more perfect.

[@KillerKev1961]

Bigger IS better! Stunning. Thank you.

[@RalfPrehn]

At least it's more stable.

[@ericbowman9237]

Wow! That slimer, purple stag, and tabling milli look amazing and everything looks very established. Well done

[@RalfPrehn]

Thank you so much, magmavander, for making good music and sharing it with us!

[@sydni915]

Very soothing!!! LOVE he way you sit waiting to see what's around the other corner of the sea floor!!![:-bd]

[@RalfPrehn]

Thank you, sandpiper! It's highly automated (water changes etc.). Cleaning work and refill of the automatically dosed chemicals takes about two hours a week. Of course there are larger 'work'events from time to time if heavy pruning of coral is needed. Removing algae from the glass is 5 min. with cleaning-magnets. It helps a lot, that the back is accessible. I recently wrote something about how I run this tank on advancedaquarist'dot'com, select 'featured tanks' on their site if you like.

[@RalfPrehn]

Thanks a lot, blackdeath! I can't say how long Slimer took to grow that big, I cut it back quite heavily. It doubles it's volume in about half a year.

[@RalfPrehn]

Thank you 2handsofgod, no zeovit, just plain old Berlin method combined with Balling-light macro element addition. Selecting "featured Aquariums" on the advancedaquarist (link in vid-descr.) website would lead you to an article, I wrote, telling how I am running this reef.

[@naturharmonie8920]

Absolute beautiful ! Your tank couldn't be better. Respect !

[@speedemon7000]

That's amazing!!!!!!!!!!! I thought my tank was awesome until I watched this. Great Job!

[@jivanchev267]

Just came across this tank. I can see it was quite old post but still it is amazing "little" reef. Congrats.

[@RalfPrehn]

Thank you! I am working in many very different positions, mostly connected to IT and IT-management.

[@RalfPrehn]

@Twelvey12able , the blue evening color of the reef together with the orange/red of the open fireplace in the room, turned out to be a real tv-killer... I agree on that :-).

[@sognatricedellefavole1202]

Just woooooow.......

[@TheShinjiNGE]

Respekt :-) Wunderschön und sehr schöne Musikauswahl dazu! :)

[@RalfPrehn]

@VAJ0hn , thank you very much, it took some years to grow in, be patient!

[@RalfPrehn]

@willamowius , thank you so much! If it's not only your name, that I know, I am especially pleased to meet you here.

[@RalfPrehn]

@desmondskyers1 don't stop dreaming! Thanks for your kind words.

[@magmavander]

Thanks for using my music ;) The intro guitar sounds aquatic, I must admit :D

[@RalfPrehn]

Most of the bigger colonies are living with me for about 6 years now, but I cut them back from time to time. I guess the long coral you're referring to, maybe is a Plexaura or Plexaurella species, maybe a Eunicea (Gorgonia) ?

[@jinhui86]

awesome reef!! how i wish i can create something like that....

[@fredd4438]

Love the brain coral !!

[@stenhome7187]

Bellissimo!!!!🤩

[@5yuser]

[@nwyk153]

[@kartikeypatel7426]

Well information. Well information.

[@RalfPrehn]

[@ripvanwinkle137]

[@retomode2865]

[@Hana-kz6ig]

Very nice!

[@RalfPrehn]

Thank you all very much, think i'll have to do a new vid the next weeks :)

[@RalfPrehn]

Thank you very much, for now, I'll have to manage just another 5 min :-)

[@JoLeng205000]

Great tank!

[@RalfPrehn]

thank you, Spanish Jo

[@sandpiper21212]

This is an extraordinarily beautiful tank. Congratulations! How do you maintain something so big? Things like trimming coral, cleaning soft algae, and removing coralline algae from the glass must be a major undertaking. Or are you able to balance the tank chemistry such that cleaning is not needed?

[@RalfPrehn]

@speedemon7000 , naa, your's is still awesome, maybe only not that matured. Thanks a lot!

[@blackdeath6544]

OMGEEEEEEEE officially my favorite tank in the world. i want my green slimer to be exactly like yours!!!!! how long did it take to get that big? mines just starting to take off its about 6 months old. VERY good my friend i thought no one could beat "a reef in the sky 3" but you surely did congrats!!!!!!! sending the link to all my friends:):):)

[@RalfPrehn]

Danke! ;-)

[@RalfPrehn]

@jinhui86 , you can! just keep on trying.

[@blackdeath6544]

also what is that big flowey coral that goes from the bottom to the top of the tank its kinda purpley grey its absolutely stunning and also how old is that acro behind the green slimer and the other stag its kinda wraps around them?

[@kentucky8100]

Nice

[@LukeGreen_]

how do you create such a nice left to right movement like that? :D

[@丁培-j9c]

Its reel reef tank!

[@TheDaddy2003]

Please share your secrets to success. Tell us everything parameters. Filtration lighting etc.

[@RalfPrehn]

Hi, back in 2012, I wrote a little article for Advanced Aquarist. It covers, maybe a little lengthy, what is my personal approach. www.advancedaquarist.com/2012/1/aquarium Thank you for asking!

[@KALZONE850]

nice. may i ask what you do for a living?

[@TheShinjiNGE]

Bitte! Gibt es mal etwas neues von Dir/Euch? :) Würde mich freuen!

[@TheToUsMiC]
