brown on rocks and coral

Could be diatoms forming because of mini cycle or cyanobacteria.

Welcome to Canreef Clownbob!!

A picture or two of your setup would help.
Are you running a skimmer currently?

[clownbob]

I don't have a skimmer and I don't know how to put a picture on here. I am new to the forum and a 3 day old marinist (is that a word?) with not even a basic knowledge. I did want to rescue this tank and give it a shot of making it look good. The 5 grand daughters all love the 2 colourful fish.

At this point all the knowledge I have is from one visit to the store. They checked the water and said that every thing was OK but I needed more salt. It was at the lowest acceptable level and they said to raise it to the highest level. I am raising the level 1 notch a day.

While there they sold me:

Chlor-out
Essential Elements
Liquid Calcium
Strontium and Molybdenum
De-Tox
Frozen Shrimp

I inherited:

Ammonia Tester
ph tester
NO2 tester
Hydrometer
Ph indicator solution/Ph up/Ph down
Eclipse filer system
Heater
Coral life scientific grade salt
instant ocean
temp guage
lots of little stuff (algae scrapers, nets, etc)

The fish are healthy and have been alive for several years in this tank. It had only been neglected for the last short while before my friend passed away.

> Make sure your temp is at around 78 degrees.
> Use the hydrometer to test the specific gravity. This tells you how saline your water is. Aim for 1.023. Instead of dumping the salt into the aquarium directly, use a spare bucket and mix the salt in pure water.
You need to circulate the water you're mixing and aim for temperature a bit higher than that of your tank. So, you will need a heater and powerhead for this. Use your hydrometer to test the salinity once the temperature is at around 79~80. Aim for higher specific gravity if you have lower amount in your tank and vice versa.
You shouldn't be using tap water for the aquarium. So, you'll have to look into buying filtered RO (Reverse Osmosis) water. If you don't have a RO filter unit, look into buying water from your local fish store (LFS) or superstore.

I think you mean 1.023.
Personally I like to aim for 1.025 (specific gravity of natural seawater)

Woops thanks for catching that. Wouldn't want to misguide up a new reefer.

[clownbob]

The temp in the tank is 78

The specific gravity is presently at 1.022

My hydrometer has the numbers 1.020 - 1.024 in red. I was going to get it to the 1.024 line. Do you think I should go to 1.025? Will this help with red/brown algae problem?

Does the red/brown algae look like this?
