| I think a lot of the above is very interesting. I still see the need for a light bioload or a very large plenum. Even using larger particles, I still see the possibility of fusing unless a balance of calcium/alkalinity is maintained via a calcium reactor. In theory, with a consistent melting of CaCo3 this should never happen but in practice a lot of things can happen.
What if ph was accidentally allowed to drop? I still see the possibility of too much phosphate being allowed to unbind possibly overwhelming the ability of the CaCo3 above it to "re-bind" it. I can see something like this happening. I.e. The main pump siezes up. The lack of circulation causes the D.O. to drop and the CO2 to increase. Then the pH will drop. If this happens, how big do the the sand particles need to be to not fuse?
I'm not trying to be a pain....just trying to get a handle on the situation. |
