Content ratios for dirt

There is a local producer who's bagged premium mix I've used to great success in the garden. Its certified for Organic Vegetable gardening, ratios are 50% peat, 25% Compost, 25% topsoil. The compost includes marine content (lots of good shell bits in it). Quite a bit of wood bits in it but thats easy to screen out.



I read that we dont want a lot of peat for our purpose, but my understanding is that the benchmark Miracle Gro Organic Choice is about the same peat content anyway ("50-55%").


Thoughts?



Sidenote: if anyone is wondering why I just dont buy MiracleGro, its not on any shelves locally, and after reading this I dont entirely trust that company anyway.

Current aquarium(s): 9Gal cube - very low tech.

I would want 50 % plain topsoil, and 25 % peat.No telling what compost could be comprised of so I would maybe not want this.
Would swap compost for clay material like kitty litter,safe-t-sorb. (help hold nutrient's longer).
Would not want shell grit unless for some reason I had very soft water for it could increase GH (general hardness).
Assuming fishes at some point are to be kept.
My two cents.

Interesting. I questioned the stuff I can get locally precisely because its VERY similar to MiracleGro, yet MiracleGro does not sound like it has the attributes NPT is looking for: its heavy on peat, ostensibly doesn't have any clay to speak of, comes with a generous heap of wood shavings, and I dont think we know the exact compost material (some of their other products mention chicken litter but I'm not sure about the potting mix specifically).

Is the ammonia from organic matter in soils that plants much prefer over nitrogen however,too much light for too long, combined with too little plant mass to assimilate the ammonia,and is prime condition for Algae.(along with possibly too little available CO2 /nutrients for light energy being used)
Many have used Miracle grow in planted tanks myself included.
Would always try and get as many plants as I could to begin with and weekly water change should help keep ammonia levels in check.
