FZONE Resin Seiryu Stone Model Ph-Neutral Aquarium Rocks for aquascaping, Micro-Landscapes

While they are a bit pricey for the size, the advantage here is #1 - the level of detail, they just straight up look like real seiryu rock #2 - they are solid, not hollow - no semi-stagnant water trapped inside, no floating. It's basically a manmade rock - feels like a rock, both in weight and to the touch. Just without the ph swinging effects of wild-caught seiryu stones Packing of the pieces was impressive - just wish they made them in some stackable/combinable shapes, or some variations that were taller for larger tanks, instead of just longer. They look a little light when dry, and darken up quite a bit in the tank Checked ph every day for a week after adding a few different stones from this line. No change, I'm confident they are indeed inert. Will keep an eye out on this brand for other future variations!

Looks good! Very heavy and seems durable too.

You heard the title folks, you can hardly even tell it’s not real. They must use sand in the casting or something, it feels just like real rock. Plants root onto it easily. It looks nice, it’s heavy. The consistency of the shapes combined with the ease of purchasing pre-designed shapes is very convenient if you’re just trying to set something up quickly, but want to have high quality looks. Rock solid to boot. Size description was spot on. Great product from Fzone, check out their co2 systems too! I have 3 and they are very good!

I love this thing. It looks super sweet in my tank

Smaller than I thought but that’s my fault for not reading. Good quality wish it was cheaper!

I originally purchased this for an aquascape that never materialized so I returned it. However, I was struck by how beautiful and realistic this Resin Seiryu Stone is. It is absolutely breathtaking and I could not get it out of my mind. I was able to get another tank and was able to reacquire this gem. It is perfect for a 10 gallon nano scape or can be combined with FZone's other Resin Seiryu Stone in a 60 cm tank. This will last forever and isn't as heavy as the real rocks they represent. You don't have to worry about your PH/GH going up and up. The price is more than reasonable and well worth it. The shipping is impressive with stone work well protected. As with everything that I have gotten from them, it is top-notch!

Fast shipping, quality product and unbelievably realistic. I’ve purchased many Fzone products in the past and have never had any issues. Quality, inexpensive and looks great! Realistic color and the perfect size for my aquarium. Can’t wait to get this tank going! ***Update*** After sometime I battled a little algae however I wanted to post an updated review. I recently ordered their mini co2 system which expedited the growth on this aquarium. After that I pulled the trigger on the Fzone pro series co2 regulator and their new inline diffuser. This entire tank is powered by Fzone products. Hands down the most affordable yet quality products I’ve ever came across. I’ve used brands such as UNS, Oase and other entities all of which are not comparable to the quality I’ve received from Fzone. I am a huge fan and will continue using all their products religiously. Thank you Fzone team! You rock!

Looks great. Packaged really well in foam, was concerned about that but it was tightly fitted in foam.

Muy real y de calidad

Super produit rendu parfait

Excelente calidad, parece roca natural. Queda espectacular en mi gambario de 38 Litros. Muy satisfecho con la marca por su atención recibida, espero que no se deteriore rápidamente y mantenga su color y textura

Awesome!

Looks great inside this tank
