CaribSea South Sea Base Rock - 10 lbs - Natural Aragonite Rock for Aquascaping, Promotes Coral Growth & Enhances Stability in Marine & Reef Tanks - (Case of 3)

These are Awesome! Used in my 20 gallon High with Freshwater Angelfish (for size reference). I followed advice from another review and rinsed really well then let it sit 24 hrs with seachem prime (or any conditioner for tap water) in separate bucket before adding to tank. Color is great, came with many pieces to build my little structure! Alot for 10 lbs , Great deal and quality!

These rocks are amazing for the price. Bought two boxes for my tanks (10G and a couple of 5 G) . I still had a few left.good size rocks, generous quantity. will definitely buy in the future when i upgrade my tank!!Make sure to wash them thoroughly before dropping them in the tank. They are pretty dusty.

Love the rocks provided. I was worried that the rocks would be brittle, but they're really good quality and there's a ton included.

The rocks arrived with no packing materials, just rocks thrown directly into a cardboard box. A few rocks were broken on arrival but you don’t get any say in what they look like anyway so it didn’t matter to me too much. The biggest rocks were about softball sized and the smallest were slightly smaller than baseball sized. All of the rocks have interesting occlusions but every rock has an overall round shape to it which I think is boring and makes it hard to create an interesting scape, especially with such similar sized rocks. I rinsed the rocks very thoroughly but because of the poor shipping conditions, chunks kept falling off and there was a lot of powder which made for a messy process. I added all the included rocks to my 6gal pico reef and it filled out the space well. This is probably my fault for not understanding live rock but it caused an enormous ammonia spike after adding the rocks, so be aware of that.I’m all for supporting my local fish store but for my first salt water tank I didn’t want to spend a fortune on it and it turned out well. These rocks were a good addition and I’d recommend them to someone trying to dip their toes into the hobby. Just be aware that this is a very cheap solution so set your expectations accordingly!

Nice sized pieces that can be glued together to make much larger structures, lots of holes ect , wash before using it is gritty from handling during shipping, I would buy from them again.

These are great tank rocks and the price is unbelievable. I’ve put four boxes of them in my reef tank and also used them to drag coral as well. Very satisfied.

The media could not be loaded. I am very happy with my rock 9 pieces 10 if you count a tiny tag along 😅 I am so happy with my purchase. The rock looks amazing in my 55 gallon i haven’t put my fish in yet but it’s looking amazing with my drift wood 🥰

I have ordered the rock twice for my reef tanks. The pieces are perfect, hardly any broken pieces. The quality is just as good as the specialized reef stores in my area but $2 cheaper a pound! I ordered another shipment. The rocks were great except it was almost 3# short. I only got 7 of the 10# I was supposed to. The pieces I got were great, but I need the rest of my order 🐠
