Hey guys, I haven't set up a new tank in a long time, so I figured why not.
I needed a grow out tank and have a 24" ray 2, so might as well do a 20 high. I wanted to try some things I've never tried before in terms of substrate, so I did.
Today I went to Home Depot, and spent $15 on two items, both of which I had no intention of buying when I went it.
Item Number One:
Decomposed Granite. This will act as my substrate and my "cap".
Item Number Two:
Ironite Mineral Supplement, 50# Bag. This will act as a source of iron.
I did very little research on these two items until after I bought them. Basically I made sure the Granite was aquarium safe that's it. After I got home, I did some research on the Ironite. Apparently Ironite is high in arsenic, however, there are many different forms of it, and I don't know if the couple of webpages I talked about were mine.
The Ironite is made up of:
1% Soluble Potash
10% Combined Sulfur
4.5% Iron (2.25% Water Soluble Iron)
.10% Zinc (.02% Water Soluble Zinc)
There are a lot of nutrients in this stuff, and a good source of Iron. So we'll see!
On to the Granite
So I spilled a 5 Gallon bucket about 3/4 full, which I don't usually do when I rinse a substrate, but I made a mistake, and just went with it. I rinsed this stuff for about 30 minutes. I literally took a chair out to my hose because my back was hurting. After filling and dumping the 5 Gallon bucket about 25 times, the water was pretty clear.
At this point, I began my substrate hill. I went back to front, starting with the Ironite and then capped with the Granite. The entire bag of Granite was a lot, and it looks a bit like Flourite Red, so I really like it. I am waiting for my girlfriend to get here to fill it because I promised she could help, but I will report my findings every couple of days on whether this combination works, and the pros and the cons.
Pros: Cheap $15 for possibly DIY planted substrate, Granite looks like Flourite, and clumps together well when wet.
Cons: Granite was a biz-flip to rinse, Ironite was kinda smelly and smeared a little, and might contain arsenic.
