Review: Great for Cory Catfish! Amazing Substrate!!! - Amazing substrate! Can’t go wrong with it! The substrate when rinsing it off is very dirty and messy so keep that in mine! It will also make your tank very cloudy but it clears up within around 4 hours (if you have your filter going, in this case I have a sponge filter) or overnight without a filter. The next morning the water was crystal clear, I’ll probably update within a couple of months to see if my plants are doing any better than the gravel they were in but I have high hopes for this soil. This soil does great for bottom feeders! I have cory catfish and a betta in a 10 gallon tank and my cory’s now love to lift their behinds up to dig into the soil because it’s so soft and light weight. I’d highly recommend this for any bottom feeders that aren’t rough with the soil because the pellets CAN break and turn into little crumbles of dust or dirt. UPDATE: Still a really good substrate! I added Ludwigia Repens to my tank and they grew so fast along with the hornwort which I added a couple of weeks ago. My betta fish loves resting on it and weaving through the overgrown plants BUT the only thing is that the darkest shade that it comes in is two or three shades light so black is brown and brown is tan. I got the black/brown and it’s a dirty brown-tan color. It’s perfectly fine because I’ll be topping it off with Fluval but this is a better bang for your buck if you wanted Fluval but wanted a big bag. Update 2023: It’s still going strong and continues to help my aquatic plants thrive! I did realize that you need to wash the soil out a lot and wait a good amount of time for the black to really set in. After a few months the color changed from brown/tan to black with spots of brown throughout. It’s been a minute since I’ve bought this soil and the price has gone down drastically (by $30) so I’ll definitely be buying myself another back to touch up on the old soil.
Review: Great Substrate for Planted Aquariums - This is great substrate for planted aquariums. I love that it is low ammonia because beneficial bacteria don’t need a lot to ramp up. I combine this with the APT S Starter Bacteria underneath and it cycles the tank in two to three weeks without fail. The small ammonia release from this substrate is perfect for the bacteria and results in zero ammonia and zero nitrite with low nitrate in a very short period of time. This isn’t nutrient rich like desertcartia but you can crush up root tabs and sprinkle them on top of the APT S before you pour in the Contrasoil for a boost. I usually do this and dark start the aquarium per the APT S instructions and the results are great. Low algae and great plant growth. Because this is partially made from volcanic ash it really soaks up things and keeps your tank clean as well. It’s strange but it does absorb a lot of impurities like advertised. This soil with Purigen makes a crystal clear aquarium. It’s definitely best for clarity. All in all, a great product. Thanks UNS!

### ⭐⭐⭐⭐⭐ Great for Cory Catfish! Amazing Substrate!!!

### ⭐⭐⭐⭐⭐ Great Substrate for Planted Aquariums
*by S***N on February 15, 2025*

This is great substrate for planted aquariums. I love that it is low ammonia because beneficial bacteria don’t need a lot to ramp up. I combine this with the APT S Starter Bacteria underneath and it cycles the tank in two to three weeks without fail. The small ammonia release from this substrate is perfect for the bacteria and results in zero ammonia and zero nitrite with low nitrate in a very short period of time. This isn’t nutrient rich like Amazonia but you can crush up root tabs and sprinkle them on top of the APT S before you pour in the Contrasoil for a boost. I usually do this and dark start the aquarium per the APT S instructions and the results are great. Low algae and great plant growth.

### ⭐⭐⭐⭐⭐ Amazing for Alocasias.
*by T***N on April 8, 2026*

I started using this for all my TC’s and young Alocasias and I can’t say enough good things. Gives my little baby plants amazing roots and strength. Only drawback is I tell everyone about it and now it’s harder to order cause it seems to be out of stock. Guess I’ll need to stock up more when it comes back.
