ADA Aqua Soil. ADA Power Sand and the other additives are also recommended by many but aren't essential.so c`mon whats the best substrate for a planted tank?
Tom Barr swears by Aqua Soil + EI. He has lots of experience (much more than me!) Others swear by Aqua Soil and the rest of the ADA range. Both methods work very well.
One thing to consider with Aqua Soil is its impact on water chemistry especially in the first few weeks of installation. Ammonia spikes, pH reduction etc. are well-known. May be best to re-home any fish whilst the water "settles".
