Anemones which host clownfish
I get a lot of questions about anemones hosting clownfish. A list of those I know of follows.

Anemone - Compatible Clownfish Species

Bubble Tip Anemone (Rose Anemone)
Entacmaea quadricolor will host:


Amphiprion akindynos - Barrier Reef Clownfish
A. clarkii - Clark's Clownfish
A. frenatus - Tomato Clownfish
A. melanopus - Red and Black Clownfish
A. ocellaris - Ocellaris Clownfish...

I think I have learned one new rule this week.

"Before any chemical experiments, check some physics." or "Before fixing things with supplements, try some water changes."

I have been somewhat concerned about my alkalinity dropping during the first week. I was looking for complicated solutions and in the end the simple one fixed it. It seems. I have done couple of 15% WC, and things are settling down nicely.

But lets start with our old...

...and it's useful to know these aren't magical rituals, but processes with purpose.

1. Cycling. 2+2=4 with most critters, but with bacteria, 1=2. They divide and multiply under favorable conditions, and fortunately their 'favorable' is pretty broad. To hasten cycling a wee bit, keep your tank temperature a steady 78 degrees and keep the water circulating to move the water around. You can 'ghost-feed' your tank a few flakes of flake food a day, which will supply any nutrient NOT provided...

So I have gone through my first chemistry puzzle. I call it "The Vanishing Alk".

As I wrote yesterday, my Alk was coming down hard over the first week of the system life. From the initial 3.66 meq/l to 2.35 meq/l after some six days. While I noted the Ca was very high at around 600 ppm.

After reading numerous pieces of information, understanding the story of CaCO3 precipitation, I have guessed that the high Ca is precipitating in the tank (indeed there is...
