Schultz aquatic plant soil. Questions.

Hullo all. I'm having some difficulty finding substrates for my price range.

The cheapest substrate I've found is schultz aquatic soil in a local Home Depot, which sells 10 lb bags for just over 6$. I've heard a lot of conflicting information about this guy, that it has a higher iron content and CEC than fluorite, that it grows plants well, that it grows them horribly, that it's very fertile, that it's devoid of nutrients... well you get my point.

I've looked at countless substrate comparisons but the most detailed and scientific ones generally just look at laterite/sand/garden soil/gravel compositions instead of the most popular commercial products. The most consistent bit of information seems to be that it is incredibly light, but I can deal with that.

My first question: should I get it? at 6$ a bag, there isn't much risk involved except for the time of setup.

My second question: should I enrich it? I've heard that people put a small layer of peat moss at the bottom. Also, I already have a bag of laterite which I could put in there if the substrate is indeed devoid of nutrients (specifically iron).

Any help or direction would be much appreciated.

I can tell you that I use it and like it, but it's very, very light.

You can get a lot of good info reviews about it by using the search function for schultz.

I like the stuff, but it is very light. I have used peat as a thin layer under, and if you don't pull up your plants much, it is great, but if you move your plants a lot, you end up with peat in the water and it takes a while to settle again.

You can use some regular gravel mixed in or on top to help hold your plants in. Don't know about nutrient value... I wouldn't think it has much if any, but my plants grow well in it with just a little fert dosing in the water.

Something so expensive and addictive HAS to be illegal. I'm just waiting for the police to break down my door and confinscate my fish food.

I dig the stuff. I have never heard a bad thing about it.

Here is chuck gadd's review of what he calls "profile".

He adds that the CEC is very high. This means that while the material itself may not hold many nutrients, it has the capacity to hold nutrients from the water and detritus in a form that's available for plant use.

here's a quick definition for cation exchange capacity

I don't think Shultz has higher Fe than fluorite....but possibly a better CEC.

I would definitely use laterite especially if you already have it. it's heavy so won't float up like peat would. This shultz stuff is like AIR man, it's practically weightless!!

Here mine 5.5g that has 100% Schultz. You can't even see it anymore since it is servely over grown right now. I cut up some Seachem tabs into quaters and spread them around the bottom before I put the Schlutz over it. The Compact sword and Hygro love it. I have to take dwarf sag and Micro Swords out about once a week. I am saving them to start a bigger tank.

10 lb bag for $6 is not worth it if you ask me.

Why not just use plain gravel with a layer of peat moss and a box of laterite?

I thought that the main advantage schultz had over regular gravel was the fact that it has a much higher CEC.

DOH! FD3S just told me about this stuff and I was pretty excited about it, mainly the cost. I was hoping that it was darker in color though because I wanted to mix it in with my eco-complete. Several of you say that it's extremely light but, does it (and it alone) cloud up the water when disturbed?

nahh so long as you rinse it good before tossin in the tank when you move it around the mess is minimal.
As to mixing with eco.. I wouldn't. the colors are very different and would look kinda funky. You might consider layering it tho with the Eco on top of the schultz. But again it will eventually get mixed and make is way to the top and will look funky. But if you're planting heavly you may not even notice it because it will be under a layer of green plants. Personally I like Schults more then Eco. Eco seems too much like crushed up lava rock where schults is more of a light clay.


btw- I wanna see your car.

I would like to plant heavily but I already have so much rock and my lighting isn't the greatest. I guess the 60lbs of eco complete will get me by for now.

Hybrid what kinda lighting are you working with? you could always plant heavy with low light plants. and just work them in wherever there is open space.

I'd say *should* plant heavy

Agreed. To me, this makes it worth it!
