Favia turning brown?

[daniellez]

Hi!

I’m new to the reef community. Here’s my tank reading..

PH ~8.2
Ammonia 0
Nitrate is .2PPM at most
Nitrite 0
Salinity 1.024
Temp 78 / 79 degrees


Salt water was premade I just fill a 5gallon jug up. I have a 6 gallon nano tank. A80 Kessil blue tuna light. Light stays on for about 10 hours a day at about 30% blue 70% white at roughly 75% intensity and sits right around 9-10 inches from the top of the water.

I don’t have any fish in my tank.
I tried zoas and they crash and melt. So I got a Favia with a green mouth and red edges. I don’t know if it’s starting to die or what... sweepers are currently out. They come out at night and maybe half way throughout the day. I don’t feed it.

I don’t check my alk and calcium (can’t find a friggin kit ANYWHERE might order online)

I took a full daylight photo & full blue light photo. I circled in yellow the part I’m concerned about. Just to the right of the yellowcircled part, you can see another brownish colored spot.

Thanks for the help!

How old is your tank?

Zoas aren't super picky - and favia aren't real bad - but very few things do well in a reef tank if the Alk is way out of whack. There's no parameter that's more important.


Bulk Reef Supply has both the Hanna alk checker in stock, and the Red Sea 'Foundation Pro' (Alk,Ca, Mag). Both are about $50.
