We used to have rocks that size covering the floor of The Tank Of Death but found that uneaten food and poop would get under there and fester - your tank looks spotless though.
As you can see in my pic's i only have a thin layer of rocks, i use cheap gravel cleaner, because they are large rocks they dont lift up and block tube but suck up the "poo" and food scrap's

Thats a very nice tank Spawn to be home made,thats awsome man!My mother would want like 5 of those tanks for her house(she has 15 fish tanks in her home,one is a 120 gal. plus two ponds in the yard...)
The cleaning thing Buck,you can go to any Walmart by you(they are taking over the world btw)and there is a suphon hose,thats the name of it I think but I use to tend to fish tanks and thats the easiest way to go for none salt water fish.All you do it attack the small end to your sink,it has a knob on the other end for sucking water out or pouring fresh water and all you have to do is turn the water on in your sink.Around me it costs like 12.99 but I wouldnt know for sure around you.They come in lengths of 10 ft,30 ft and 60 ft,it may do you guys some good so Im just saying:).
I may be female and young but I have enough courage to suffer this death and thousands more.
