Oh yah, and I notice that Bang Guy didn't take my link down.

I don't think it is a no no to post links to informative articles, so I am posting this link to an article that showas the sg conversion based on water temp. It states that hydrometers are calibrated to 60f. If you use a hydrometer you should be aware of the change based on temp...

Here is alink to the article that Noah referred to. I least I think it is the correct link. http://www.majesticreefs.com/Majesti...a_Density.html

I use a refractometer to measure salinity. When i used to use a hydrometer, I had a conversion chart for SG to PPT based on water temp. If you aren't using a refractomter, I strongly suggest getting one. I couldn't believe the amount the hydrometer was off when I switched.

Which is more important to look at. Since salinity SG is influenced by temp but PPT is constant shouldn't we look more at PPT? My SG is about 1.028 yet PPT is 35. I often read that we should keep salinity at 1.022 or 35 PPT. Should I reduce the SG or maintain the PPT of 35. Let's have a...

Aptasia? Doesn't quite look like what I ususally consider to be Aptasia. Is it just a different strain or something else? Thanks

About 6 weeks ago I noticed that my CA had gotten up to over 600. I have finally gotten it reduced to it's current level but while it was high I continued to had high amounts of Randy's alk mix to try to get the alk level in balance with the CA. I was raising the dKh to close to 20 or more.

My tank has been up for about 5 years and I have always Coraline growth. I have needed to scrape from the corners weekly. Now I get none and only a hard green algae growth in the corners where the mag cleaner has a hard ttime getting to. Why no more Coraline growth. I want it back Water...

Right now my calcium level is too high (520). My question is should I strive to get my alkalinity in proper balance which would be about 22 dKh. Right now it is about 11. I use the chem calculator to determine what the proper balance should be. Or, just maintain the alkalinity at a level to...

I use RowaPhos in a phosphate reactor and have been very pleased with the results. Do you have a refugium? Macro algae is also good at absorbing phosphate. Do you have an algae problem? If so it will absorb and grow from the phosphate and just release it back in the water.

Ok, what to do about it? What is the best way to trap it or otherwise get rid of it?

Any idea what this might be. He only comes into view briefly at feeding time and is very quick to get back into the rocks. There is an orange spot on his head and he is brown in color. Two buggy eyes and if it was outdoors and green I would expect to find it on a tomato plant lol.

I am adding 2 cups of Randy 2 part formula every day and dosing about a gallon of Kalk and my calcium stays at about 350. I am also getting calcium build up on the impellers of my pumps and power heads. Is this calcification on the impellers normal? Also the sponges on the pumps get full of the...

I wrote last week about low CA and clogging of sponges and impellers and we (you) decided it was due to precipitation but unsure where from. My theory I have been dosing Kalk for about 4 weeks without doing proper research or reading (my bad). Inadvertently some of the Kalk percipitate was...

Bang Guy Answers to your questions How are you dosing the limewater? What time of day? How are you making it? I am dripping the kalk at about a drop a second. Usually during daylight hours. I make it by adding 4 teaspoons to 2 gallons of water and shaking vigorously. I then let it set for a...

What does every one think of this skimmer? Is there a better choice for my 90 gallon with a 30 gallon sump? Thanks

The salt mix tested at 420 CA, 1400 mag and about 10dKH

My CA is 310 and dKH is 8. PH about 8.2. I add 1/3 cup of DIY part 1 and 1/3 cup DIY part 2 every morning and am also dripping Kalkwasser made with 2 tsps in a gallon of water. I drip about 1 gallon or slightly less per day. Tank is a 90 gallon and I have a 29 gallon sump. A large open brain...

One more thing. I also do a weekly 10% water change.
