Example of impact of CO2 levels on Marine EcoSystem

Hi well everyone has been hearing about global warming and rising CO2 levels. Well the rising CO2 levels are acidifying the ocean, driving the pH of the ocean down as CO2 levels rise. This is a very bad thing, as Corals and marine life live in a very narrow band of acceptable PH levels between pH 8.1 and pH 8.4.

Corals grow by creating bicarbonate skeletons, this is what creates the beautiful corals reefs and ecosystems that support the huge abundance of life in the oceans.

However, when pH levels in the ocean drop below about 7.8 calcification stops and corals start to disolve.

Below is a graphic example of this. My marine tank is in the basement, When my son has a sleep over with his buddies, 4 extra bodies exhaling CO2 drives up the CO2 levels and lowers the pH in the tank.

My 150 Gallon tank 4 months old

Hi there, well the video below is of my 150 gallon tank after 4 months and after the hottest summer in Burlington I can remeber in a long time. The fans for evaporative cooling worked just perfect.


In the video you will see a number of fish.

FoxFace Lo - a curious fish, the one with the black & white face and yellow body. His is an algae eater and very well behaved community fish. He always puts up with the yellow tang pestering him. The FoxFace Lo's dorsal spines are extremely poisonous....so you do not want to be touching him or trying to catch him by hand. Another interesting behaviour of the FoxFace is that he can change colours to camoflouge into the background, he can go from bright yellow to black or anything in between...

The other fish are a Hawaiin Yellow Tang and a Pacific Blue Tang and Yellow Tail Corus Wrasse ( Juvenile) see earlier post about how this fish changes has it reaches adult hood.

There is also a blue streak cleaner wrasse....this wrasse cleans the bigger fish, and picks at them.....the bigger fish let this grooming occur as it helps them....and probably feels good too. ( you can see this in the video above)

There are also a few blood red cleaner shrimp as well and they also will climb on to the bigger fish....and groom and clean them.

New 150 Galon Build

Well everything was getting bigger, my Tangs, my YTCW and my corals so I bit the bullet and upgrade to a 150 Gallon system with a 80 gallon sump.

Here is a video of the new tank after I set it up in April 2010.
