how long for a block of MarinePure to colonize BB?

[RioReefr]

After reading so many positive reviews, I decided to get the 1" block of Marine Pure. Approximately how long might it take for it become beneficial?

To speed things up, I dumped a 1/2 bottle of Instant Ocean BIO-Spira into the tank. Just curious how long it might take for the BB to colonize inside the MP?.....days, weeks, months?

One week should suffice IMO, but the longer you wait the better.

I would have soaked it in bacteria before adding it to the tank. This is the best way to just start your block.

I still have a 1/2 bottle. Could I take the MP block out and soak in there for like 24 hours? At this point, the block has been in my tank for 3 days. It is stocked with live-rock, live-sand so I won't upset the system (too much).

I would soak it overnight.

This is what I have done. I took the block out and placed in a tuperware container. I took tank water covered the block, probably 1 1/2 in depth of water. I dumped the other 1/2 bottle of Bio Spira into there. Additionally, I took a tiny bit of shrimp (used to feed my fish) and tossed it in there. I figured the bacteria need something to feed off.
