Nature's Ocean Bio-Activ Live Aragonite Reef Substrate, 8 lbs

I bought this sand for my refugium connected to my 75 gallon reef tank. It is a nice substrate that did not cloud the water longer than an hour after adding it (I have had other sand substrates cloud the water for days, literally). I had no problems planting my macros into the sand, and the piece of live rock that I placed on top has already seeded the sand with pods. My refugium looks great and is the perfect addition to my healthy reef tank.

Pretty awesome product! I ordered 2 bags for my reef aquarium and it did just the job. It has a random assortment of little shells and stuff in it so it gives it a more natural ocean look.

Mine arrived in the original bag, inside of another bag. There was no hole or any damage to the original bag. It was still plenty "wet" and appeared to be exactly what I thought I'd get. It was 8.55 lbs of small shell pieces and fine sand. It in finer than the CaribSea aragonite pink sand that I previously had, but settled in less than 12 hours. Make sure to actually open the bag before you decide it's dried out. The liquid is hard to see near the top of the bag. You'll notice it more near the bottom. For the price, it's a good deal. I can't speak for instant cycling ability, yet, because I plan to do tests this evening after placing it in the tank last night.

This was perfect for my 10 gallon saltwater tank. I wanted about a 1 inch layer on the bottom of my tank, and this was perfect-especially for the dwarf seahorses I am about to get. You may want to get something that sifts sand, though (I am getting blue legged hermit crabs at $0.40 each). Arrived earlier than expected, which was great, because my seahorses arrived a little less than a week later. Thumbs up to this product. Arrived like expected in physical appearances, besides the fact that there where broken seashells and almost-microscopic mini shells buried deep-plus about an inch-long branch of live rock. Update; Hermit crabs love it, and so do dwarf seahorses. Hope this review was helpful, answered any and all questions you may have, and anyone who is skeptical of this product due to negative reviews changed their minds about buying this product.

I like how there are small shells mixed in with this sand. I bought this to add more sand to certain areas of my 120-gallon reef tank. I do not have the cloudiness issues others seems to be having - I used a large fish net to carefully lower the sand into the tank, with all the pumps turned off.

What is shown is an 8 pound bag of substrate. What you get is a 10 pound bag of white live sand. So the product shown is not what is delivered. I returned it to the store because I need the substrate for a mantis shrimp. The product is great sand but it got one star for not being what is shown.

Great substrate for helping that nitrogen cycle really compress. I used this with a stabilizing additive and it compressed my cycle to about 3 days. Normally you’re waiting a month with the old “add some hardy fish and wait” method. Clouds up your water for the first couple days but just be patient. It will clear. You can’t wash it off before adding it because it would kill the bacteria so what do you expect? Nothing in a reef tank ever happens quickly.

I was very disappointed in the substrate and glad I only ordered 8 lbs! It has a mix of fine sand ald larger pieces of all types of shell. Looks starge once you spread it out, you end up seeing the shells rise to the top of sand and some of the little broken shells are orange, black in color, so the orange little pieces makes it so I have a hard time distinguishing from whats left over fish food thats fallen to the sand. I am always turkey basting leftover food and I cant tell whats what! Looked beautiful in the window of bag but not when you lay it down. Looks just like the first pic with all the shells on top of sand!

La arena es excelente, se ve muy bien en la pecera ademas de brindar beneficios al ciclo del agua. El tamaño aunque no es muy grande se mantiene estable a pesar de la corriente interna

Excelente mi producto !!!!

Lo ocupé para un acuario de cíclicos, buena relación precio calidad

Buen producto costo beneficio
