Brad's 100 'n Change Cube-like Journal

[Aquattro]

So, new month, but not posting a pic. Looks just like last month but without fish.

Started VSV dosing last weekend, overall impressed. However, while the NO3 was cut in half, PO4 went up. Skimmer took out tons of gunk, especially compared to what it did WITH fish. This last week gave twice as much skimmate.

This tells me the following.. excess bacteria were created via dosing. They used half the nitrate available, and a corresponding amount if PO4. Not sure what the ratio is, but P should have dropped over the week. It went up 20%.

So it appears that the rock is leaching faster than dosing can remove it. Not surprising.
I'm ordering a couple boxes of real rock and will rebuild once I get it and cure it. Maybe I can finally get some growth out of the corals.

It'll be fun! (riiight)
