I'm looking for a cheaper alternative for my base substrate for my 4x2x2 tank. I'll be growing crypts, tenellus and probably java moass on the substrate w/o Co2. Can anyone recommend me a good & economical alternative rather than ADA? I was thinking Lapis sand with base fert but i don't know where to get large quantities of the above any our nearby LFS. How much is a bag? I would sure appreciate if anyone can point me in any direction

TIA!
