Dry Rock Suppliers

Everyone has good points,

Though my understanding from Adding LR to Dry rock would be to add the benefical bacteria for to reduce your cycle time. That being said the more LR you add the better and the faster your cycle will be done. As greg suggested if you add 1/10th LR to Dry your cycle will take longer as if you were to add 50-50.

I added about 25 lbs of Dry base rock and about 30-40lbs of LR and I didn't even see a cycle in my 65G.

As for adding Coral / Fish / Clean up crew. You should wait until after your cycle. Some choose to add the clean up crew during it's really your choice I myself would suggest after. As for adding fish and Coral to your system after your cycle do as you normally would. New fish every 1-2 week as suggested I'm sure would be fine.

Thanks alot for the information, it has answered a few questions that i had. As for tank size I am considering a 75g or 90g with a 50g sump, if I have enough plexi glass. Does the type or live rock make a difference in regards to filtering, or do people select rock just based on appearance?

The type of rock makes all the difference. You want a nice light, porous rock. Heavy, dense rock, whether it's live or dry is useless, and will just lead to frustration with your nutrient levels.

That is not 100% true. Rock that is too porous can be also problematic. Dense rock has the anoxic areas that harbor the bacteria that convert no3 into nitrogen gas.

I mean the structure of the rock itself, not that it necessarily has more passageways etc... though this is important as well IMO. Water needs to be able to penetrate the rock in order for it to function well.

That has little to nothing to do with what makes live rock function.

Interesting, please explain.

The more porous the live rock the better, this means more surface area for benefitial bacteria to thrive
