Pisces USA Seiryu Aquarium Rock, 17-lb bag

Have had this for like half a year now or so and over time the rocks just degrade in the water and is a algae magnet. I only have my tank light for 5 hours a day and no windows directly shining on it. Writing this review now since it started happening 2 days ago

I originally ordered 2 bags of these rocks. 1 bag came with two large rocks that werent seiryu, they looked like plain grey granite chunks. The bag was also cut open. The other bag was a good mix of seiryu stones of all sizes but also had a few random granite stones. I called chewy about the bag first bag and they sent me a new bag with no charge right away. Props to them for good customer service. The new bag I got had a few medium sized seiryu stones and another random granite stone. I have no problem with chewy, but whoever their supplier is for this rock seems to be mixing in cheaper stone with the nicer stone. So expect a mixture. I would definitely recommend buying two bags so you have I originally ordered 2 bags of these rocks. 1 bag came with two large rocks that werent seiryu, they looked like plain grey granite chunks.

I would definitely recommend buying two bags so you have enough to play with. But overall a decent price for what you get especially compared to a LFS that charges 5$ a pound. This route is still cheaper even with a few filler stones. … more

My understanding was that I would get 1 large rock and several others. The picture lured me to think I would get rocks of various sizes and shapes. That was what I expected. Instead I received 2 huge rocks (each ~9 inches and about the same shape) and 2 pebbles (which I do not consider "several others of various shapes as pictured"). I cannot use 2 rocks of such a huge size in my aquarium. I will not buy from this company again.

Good thing these are out of stock, DO NOT WASTE your money. Bought a few bags thinking it would be half decent, they will give you a boulder that weighs 12-15lbs and 1-2 extra small white-ish seiryu.

I ordered 2 bags, both had several 2-3 inch seiryu and 1 large heavy rock that obviously wasn't the same. 1 bag was ripped open and it also had a couple hand sized nonseiryu with the large obvious rocks.

The 17 lbs of rocks consist of one giant rock that weighs 15 lbs and small bits of rocks of ~2 inch dimensions making up the remainder of rocks. So they're essentially useless for stacking for mbuna cichlids.

It comes with one giant rock and a lot a smaller rocks. I bought this in hopes to design a iwagumi with it and I’m disappointed.

Before you buy this product know that you’ll likely get one large, heavy rock and a few smaller ones. If you can buy rocks from your LFS you’re better off.

I was kinda freaking out because of some of the negative reviews on this company, but overall I had a pretty good experience. This is about 40 to 45 pounds of stone in my 55 gallon. I had to order 3 bags for the look I was going for.

Different sizes inside to fit your needed look, buy 2- 3 , great price too
