Starting dirted tank, plan to have a gravel cap but don't really know what to put in for dirt. I want the tank to be heavily planted, and it will have high light. What are your favorite dirts/mixtures to use, what would your recommend?
Go mineralized topsoil. I'm formulating what I consider the 'ultimate' soil substrate, testing will commence in the upcoming weeks.
+1 on mineralizing first. Soil or mix. It was recommended to me to use miracle grow organic potting mix, and it's been fine since I finally have the junk cleaned out. But it was a real pain at first. I wish I had mineralized first. Actually Diana Walstad also recommends the mix over the soil. Can't wait for your results jeta.
I agree mineralizing helps alot but doesn't have to be done. And everything I ever read about Walstad said organic potting soil, potting soil, or top soil and in one article it actually said Miracle Grow Potting Soil.
