When will I see spikes in cycling?

[Kinghugo5]

Hi All,

I got my RO early and started my 72 g bow front yesterday. I added 70 lbs of live rock and 40 lbs of Fiji pink live sand. I’m going to go get 2 more pieces of live rock today because it isn’t as much as I ancipated so we’ll say I’ll have 85 lbs total. I’ve been running my HOB octopus skimmer and running lights. Have a total of 1275 gph.

Just out of curiosity I tested the water today and all levels were zero and the PH was 8.

I’ve read that sometimes only a small cycle happens when prepared this way. Is this true? Or should I expect to see some spikes within a couple weeks.

Thanks!

Nate

depends on how much die off there was in the rock and sand, if any. if you took them straight from a fully established tank, with zero die off, then youvmight not have a cycle.

btw, i hope youvmeant rodi instead of ro.

I may wait a week just in case.

Yes - sorry! Had a different post where I was waiting for the RODI system to be mailed.

Thank you for the reply!!

If you want to know if it is cycled for sure, add a little bit of ammonia. If it is fully cycled, the ammonia should be gone in just a single day, so you will not have to wait long and you can be confident when putting in your first fish.
