Most Beautiful Private Reef Tanks! **400 GALLON**

I visited Lars a Dutch Reefer who owns probably two of the most beautiful private DIY reef tanks in the world. Lars had invited me to visit his koi pond, unfortunately we ran out of time. The reason? Lars owns one of the best salt water aquariums I have ever seen. What do you think of this amazing Reef tank? Let me know in the comments what favorite corals and fish you like!
