Potting soil bad or good for a planted tank?
I just started a planted tank and was wondering if potting soil is bad. I already put it under my tank :-?. So my tank has potting soil with no fertilizer and a layer of sand over it. The thing is when I added the water some of the potting soil came out and settled on top. My filter cleared the water up tho. So is potting soil bad for my tank?

I would Have to say that requalr garden potting soil is bad for the tank as it can contail chemicals, and roots, leavs, and other things that float to the surface.

I would Reccomend using miracle mud or some sort of freshwater nutrient

well depends on what type of potting soil. If it has no additives, it may be fine...

From the little research I just did it says as long as there are NO additives it's perfectly fine to use, as SinCrisis has posted. :-)

if your worried you could try running lots of carbon in your filter so it absorbs as much gunky bad stuff as it can. otherwise, i dont think there's much you can do since its already added.

as you found out it will cloud water easily so if/when you go to add plants to the tank be careful doing so.

i dont know how well it will handle a gravel vac.

Im kind of curious why you want to use potting soil. Would it be better for a planted tank?

ive seen a tank use soil, althouoght i dont know if its potting soil, but some kind of dirt at the bottom of the tank and the owner said that it made his plants grow really fast.

The dirt might just absorb all the poo and stuff so you might not have to gravel vac and just change the water. Also teh sand will inevitably sink into the mud anyway so any gravel vacing would just suck up all of your soil.

Those interested in soil substrates for planted aquariums might wish to google "Diana Walstad" Her method suggests placing the plants in the soil before covering with gravel to keep clouding to a minimum. The method has been used successfully by many. I would submit however that soil eventually gives up all it's nutrients perhaps quicker, than substrates such as flourite or some of the other pricer plant substrates.:-)

My friend gave me a 45g w/rocks over soil ,well whrn i added water it was black and worms hatched, that marcide could not kill. I was onlt trying to soak the rocks to save tnem, but after what i seen i decided not to keep the rocks much less the dirt. I would certainly wait some time before i added fish.
