Hi Guys
As you might know I have just drained my tank and am now left with limestone base rock and Aqua Medic Calcium carbonate as substrate.
My decision now is do I take the base rock out and sand for the following reasons.
1.They may have absorbed P04 and release it back over time when I put new water in causing more algae growth!!!
2.The die off of bacteria from draining the tank would be pretty harsh and prehaps cause Ammonia,Nitrite or Nitrate spikes when the tank is refilled.
I have in the meantime saved my live rock in my sump.
If I choose to chuck the rock and sand then I will go bear bottom and try to purchase liverock as and when I can afford it to supplement my existing liverock.I need many kg`s!!!
Would you chuck the rock and sand and have a bear looking tank?
