Review: A terrarium trend - Some of the leading people making terrariums commercially have started to incoporate aquatic peat, so I thought I would add it to my supplies and try it out. While I cannot attest to how long it functions for filtration, nutrition, or even before breaking down. But, I can at least comment on it's texture and base function as an aggregate. It should be noted, that this is a material designed to be used in aquarium filtration systems. When you pick up a single granual and pinch it very hard, most pieces will not crumble in the way perlite would. I would compare this product's texture to something closer to akadama or pumice, though I honestly hope it is more durable, as many people do not realize that akadama and pumice will break down over only a fairly short amount of time. My favorite aggregates are calcined clay or lava rock. The granuals here are comparable in size to the smaller grain calcined clay or standard perlite, though notably much more rounded and I expect that to contribute to helping them not break down just in terms of being a functional aggregate in a drainage system. In terms of providing filtration or mineral nutrients, I expect these to help filter the standing water until they start to break down physically. There is some talk that horticultural charcoal pulling nutrients out of the soil and if those nutrients are released once the hydrophobic bits finally take in water and break down. I do not know the scene enough to clarify those aspects. But, I expect this material to benefit my terrariums long enough that when it wears off maybe my terrariumns can be balanced enough on their own by then. Regardless, this is a very affordable product with a consistent scale that is practical when layering in conjunction with calcined clay, brown dirt, or red lava rock, but also when mixing with charcoal and black lava rock for a robust drainage system that filters in multiple ways. I plan to keeep this on hand unless I see signs of trouble. So far so good. Try it! It's cheap enough.

### ⭐⭐⭐⭐⭐ A terrarium trend
*by J***N on January 9, 2023*

### ⭐⭐⭐⭐ Will slowly lower the PH
*by P***F on November 30, 2020*

I was having a major PH issue and needed to make the water a little more acidic. My tank really wasn't big enough for a piece of driftwood so this was the next best option. I put some in a bowl and rinsed it well and put it in a bag in my HOB filter. It has not lowered the PH all the way to a neutral 7 but that is because I have not added enough. It got it from 7.8 down to 7.2 or so. Everything is stable now. The fish are happy and the algae is nowhere the issue it was. I can add more later if needed but don't want to risk any kind of crash. Keep in mind I didn't use a whole lot and I always run carbon but there were no tannins at all that discolored the water. It is crystal clear and now has a safer PH. I put it in a zip lock bag and have plenty for any need in the future.
