We (SWOAPE) should be getting in a large load of Soilmaster Select Gray (Turface Gray) later this week. I'm not a very big proponent of substrates since I rarely miss dosing my tanks. As long as it hold the plants down, I am pretty happy. But for those that may miss dosing here and there, would it be a good idea to add ferts to a solution and soak the Soilmaster in it?
I was planning on adding some KNO3, KH2PO4, K2SO4 and CSM+B to some water and soaking the Turface in it for a while before setting up my tank. It will be a few weeks before I set up my tank so I figured I could "test" it out. However, there are a few in the club that have already waited a few weeks on the substrate and are in a hurry to get their tanks set up!
Other similar type substrates seem to be failry absorptive (or is it adsorptive?)and hiss when rinsed, kinda like activated carbon. It would seem these clay type substrates would absorb (adsorb) some nutrients if soaked in them.
