LIve Rock turning color...Brown!!

[Wolverine57]

Recently, this past Saturday just setup my ne w 75 Gallon. And notice many tiny bubbles in my tank and on the rocks. In addition my rocks seem to be turning color, like brown.....Any idea. Hope its nothing serious. There is no corals in my tank yet. Just fish only, same fish I had from previous tank.

In my 20G long tank (sump I have a Aqua C-180 Skimmer pump connected to a mag7) on the return a Mag9.5. Inside the sump I have lots of live rock. One more thing, I have no live sand (bare bottom) using cutting boards. Thought to give as much information to see if I am doing something wrong or missing something. Hope I can get an answer or HELP!!! from the pros here at MR.
Thanks

It's a common occurance with new tanks, it should pass in a week or so. I would'nt be worried right now.

Sounds like Diatom algae to me. But if you set up the tank this past Saturday, then the algae shouldnt be coming this quick.
First off, did you use Revese Osmosis water?
Were your rocks cured?

But honestly you shouldnt fret, these are typical occurrences with a newly set tank. It can take close to a year for a tank to stabilize biologically. The beginning months are the hardest.

if you are running the lights for a long period, that can speed up the diatom growth.

Are you say to run my lights longer? I have 175 HQI MH

no, the opposite.

 

[jawwad2004]

First off, what is your current photoperiod? Are all the bulbs new? Are you using VHO/T5 supplementation or just MH?

Currently I have these light, purchase from Peeshee! SunPod HQI Metal Halide 48 inch w/ 150W HQI Bulbs: 2 X 150W MH Lamp, Blue and 9 white lunar lights [FONT=Verdana, Arial, Helvetica]

if your tank is cycling and you have no coral there is no need for the lights to be on

but I have fish, from previous tank

can u list your water specs? using ro or tap water?

 

[Wolverine57]

Craig I do not have a RO system yet. Recently, I've been buying water (Deer Park). Peeshee, said he is coming over this Friday nite to test my water.

Hey Johnny!
Your Brown diatom algae is cause by silicate!!! I'm assuming that silicate is present in bottles of Deerpark! *^^* Well most people can quickly suck out portions of it, its better to remove their energy source, silicate!
Here is the Rx for your problem:
desire level of pH is around 8.41-8.46 ; slowly drip Kalkwasser into your tank, you'll precipitate silicate, phosphate and add calcium!
do this and it will all go away in about a week!

Sincerely,

Firstly, I want to thank everyone feedback, its appreciated! Its comforting to be part of a group, that cares. And on that same token I want to express my graditude to Peeshee (John). Thanks John, to come to my home and test my water parimeters, that was the maxiumum. That's what I call service, coming from Queens. I will definitely, refer you to anyone, for your experience and honesty! Thank you.....Maggy & I look forward for you and the fianace for a nice PR dinner!
