    • My favorite LECA
Size: 25 Liter Bag Pattern Name: Bag
I bought this LECA because it was the cheapest I could find for the quantity. As others have mentioned, most of it is not round. If aesthetics are concerning for you, this LECA isn’t for you. I actually think all the variation makes the LECA fit together nicer, and I actually get better results with it. Yes roots stick to it, but roots stick to the round ones too. Yes it’s a little dusty when you get it, but what LECA won’t be? They all rub on each other during shipping. Just rinse it and it’s completely fine. No they do not sink. I don’t know what makes these different than others, but they definitely always float. It doesn’t really bother me, so that’s not a concern. Having said all of that, I’m very happy with it for what it is! It works great and the price is right! ... show more

    • Worked great in my 55gal flood and drain system
Size: 40 Liter Bag Pattern Name: Bag
Review Image by John John
I bought these for my flood and drain set-up. You have to clean these very well as they have a lot of powder from production. As I was cleaning I was worried because they all floated. I made sure all of the water was out of my barrels and filled to the top with rock. I then flooded them and I was very happy because the weight of the pebbles where enough to keep from floating up and over the sides. There is also maybe an inch of dry rock at the top of my system to prevent the growth of alge. They are perfect for my halfbarrel flood and drain. Also if your interested took just about 6 to fill 2 half barrels. Its a lot of money but after digging out my $150 of rock that tested fine with vineger but then the ph started creeping up was not fun either. This pebble is so light and easy on the hands to work with and should withstand for so long I'm happy with the investment. ... show more

    • Clean them thoroughly, works well
Size: 10 liter Pattern Name: Bag
I used this to act as a drainage medium for a reptile vivarium. A lot of people complained about the pieces not being perfect balls. For me, this didn't matter, especially since when I think of "pebbles," I tend to think of imperfect little pieces. The clay pebbles do vary in size, with a marginal amount being tiny enough to slip through a strainer. However, it is quite a large bag and I had plenty leftover. For my purpose, it works quite well. It helps to keep the humidity in the tank without leaving any standing water. I have yet to see any sort of mold or fungus growth. I am quite pleased! Hint for cleaning: I divided the bag into manageable amounts and used an old strainer to rinse them off with the hose until the water runs clear. This a longer process but helps to thoroughly rid yourself of all the dust. I originally tried just throwing everything into a large bin, filling with water, and pouring out the water but I still ended up with dusty water. Do yourself a favor and clean thoroughly the first time around. ... show more

    • Good product. Quite a bit more dirt on them then what I've gotten in smaller quantities.

Product is good, weights were on point. I had to work a bit harder washing them clean. Other than that, the product works as it should.

    • Love these
Size: 40 Liter Bag Pattern Name: Bag
There is a lot of crabbing about these to the point that I wondered if I made a mistake purchasing them. What I found when they arrived was pretty much what was described. Yes, you do have to wash them before use but I actually liked the process. Sometimes people over think things and make it harder than it has to be... I used a dollar store pitcher, the kind that if you turn the lid one way you can strain your drink or if you turn it the other way you can just pour. I opened the bag... used the pitcher lid like a scoop... scooped the clay pebbles into the pitcher... filled with water and pushed them down a few times.... turned the pitcher top to the strain position and drained them... filled it up again and erepeated the process...after draining the second time I filled the pitcher a third time added some dechlorinating stuff to the water because I used my hose for the rinsing... and that was about it... took ten minutes tops... if your doing a lot of these I would still recommend the pitcher for the first two rinses and then maybe a tub for the last soking... I think it's a good product at a good price and no I didn't get paid anything for this review... it is just my personal experience with this product. Thanks L. ... show more

Love this laca pebbles. This is a really big bag and amazon had it cheaper than my local store. For indoor plants I recommend to soak them up in boiling water as others mentioned that some flies were coming out so wanted to stay protected and kill all the bugs/bacteria’s although didn’t noticed any just as a precaution ... show more

    • Bad Quality
Size: 40 Liter Bag Pattern Name: Bag
I built an aquaponics system for my daughter and filled the grow bed with two bags of this media. The media was extremely dirty and ended up clogging my laundry sink. I’ve never had anything clog my laundry sink before but the excess clay dust from this media did it. Despite soaking the pieces for a week, they still float. Most of the pieces are broken and there are a lot of really small pieces, the size of gravel that can wash down into the fish tank and cause issues with your pump. After figuring out that they don’t stay in place and float, I ended up getting pond rock from Lowes and using that to fill up half of the grow bed. I then used 1 bag of this media to complete the grow bed. This was a lot cheaper and worked a lot better. If I had to guess, I believe this is seconds or perhaps defects that are sold as firsts and for the price, that makes sense. I found much better media from another vendor. The biggest difference is the legit clay sounds like rice crispy cereal when they get wet from all the pores soaking up water. These definitely do not do this. They are more like lava rock or something weird. ... show more
