Ocean Rock Pod Farm

[HappyGeorge]

Well I know Ocean Rock doesn't help filter the water and I had removed all but one piece from my nano, but the firefish had been rather enjoying living in one of the holes. I have now removed all the LR from my nano to stick it in my 5ft tank for the final scaping.
So the last thing left was the Ocean Rock I put my hand in lifted it up and out flowed dozens and dozens of pods that had obviously been living in the Ocean Rock. I know a LR rubble pile is a good way to make a pod farm but this experience got me thinking.

The Ocean Rock obviously does no harm, it doesn't absorb water so doesn't need huge flow, it has nice large holes for lots of things to live in and although it doesn't help with filtering, it at worst could buffer your water, it certainly doesn't get mucky as this lump has
been in my nano for 6 months and with 0 Nits and Phos it obviously hasn't done anything.

So just thinking I might just stick a couple of bits under the piles of LR in my 5ft tank. Is it one of those things where everyone says don't do it but no-one has any experience of it ever causing a problem?

If you want some mate, let me know as I've got loads of it. Small and large pieces.

Cheers Woody I do have a fair bit and I did initially use it in my nano until I was advised to take it out, didn't even realise the last piece was in there. I can't help thinking it may be better than LR rubble, if it's under a pile of rock and getting very little flow then surely better to have a non porous rock with a few big holes rather than one with loads of places detritus can gather?

If you stick dry/ocean rock in with live rock, all the little things that live on the live rock will eventually reproduce and colonize the ocean rock as well. A lot of people do this on this side of the pond.
