broccoli smell coming from newly started tank

[jokersplayground]

Ok so i just started a tank with all dead rock, rinsed sand, and ro/di water. For some reason it smells just like broccoli in the tank. As i was adding water i started smelling it. So i thought maybe it is my ro unit but i smelled a fresh batch of it and it does not smell. I am stump. I just started the cycling today. It took me 3 days to fill the tank though. Im hoping you guys may be able to help me. Thanks in advance.

How did you clean the "dead" rock?

 

[jokersplayground]

I used ro water. It was dry for 3 weeks

Probably die off.
Any chance you could boil it outside and sun bake for a week or two, then re-cure in a separate container w/heat &power head?

It dont stink up the whole house. You can only smell it if you sniff the tank

you should probably have cooked the rock. By cooking, I don't mean throw it in the oven. But rather, cycle it in a tub in the basement with no lights or anything. Just water movement and a skimmer.

If the rock was live, then dried for three weeks you can probably expect it to gradually stink a LOT more because it's likely full of quite a bit of dead but not fully rotted organics.

I agree, I'd take that rock out and cook it for a while. IME that cooking can take up to a few months and you don't want that happening in your tank with livestock in the smelly stew.

Woke up this morning took a sniff and the smell is gone. Thats weird.

I still wouldn't trust it. Ive had issues using dead rock that wasn't properly cured before. In the long run, I ended up still basically needing to cook the rock, though this occurred in the tank, I just didn't have anything alive for 2 months. This was way back when I first got in to the hobby and well before I knew of BRS.

Yea i dont plan on getting any live stock for a long time. I want to get a few more pieces of equipment which it will take me a couple of months to get. These rock i had before in my old tank they where in that tank for i think 4-5 months and they was still white in color as they are marco rock. I dont have a tub i can put them in to cook. Ill just run carbon if it gets out of hand again.
