Bump, bargain prices for the long long weekends

Is it just be or is half of this thread the (not very) grown up equivalent of "but he did it so why can't I?".
Two points which have been made:
There is rubbish in the ocean, so nuclear waste is not a big deal.
There is already nuclear waste in the ocean, so why stop now?

Really??? There is already carbon dioxide in the air we breathe, would you have a problem if we bumped that up to 10%? Or chucked in some chlorine too? There needs to be sensible limits and requirements for treatment for all waste before it is released.

If Japan didn't want to deal with and treat nuclear waste they should not have built the plants.

Quote from the actual source (abc news):

He believes that after the water is treated and stripped of most radioactive elements, it will be safe to dump into the Pacific.


Not saying what they are doing is right, but emotional reporting is what gets the green movement ignored in the first place. Real reporting is finding out what treatment and what levels they consider acceptable? Where I work we have waste water containing hexavalent chrome (the carcinogen that made Erin Brokovich famous) which is disposed off into sand filled soakwells. Sounds horrible! Of course I left out the treatment we do first, reducing all contamination levels to drinking water and separating all chrome into solid waste, backed up by independent lab testing and continuous ground water monitoring.

Not defending the dumping of dangerous substances, but some of that reporting is almost as toxic.

I was wasting some time on YouTube tonight looking at people's fish tank ( I know what a loser ) and one of the videos was talking about using an organic carbon source to reduce nitrates. Does this sound right? And if so, how do I feed the aquarium this organic carbon to keep the nitrates low?

Yes I know the only way to remove nitrates is water changes, but if there is something that I can do to keep the fish happy in between water changes then why not right?

 

Carbon dosing is more common in salt water.  The carbon encourage bacteria growth which use nitrogen (from nitrates) and phosphate, this bacteria can then be removed by skimming and to a smaller extent be used as a food source for some corals.  The carbon source can be sugar, vinegar, alcohol or plastic bio-pellets.  The same bacteria can be encouraged to grow in fresh water but then it becomes a problem of how to remove the bacteria before they die off and release the nitrates and phosphates back into the water.  Anaerobic bacteria use the oxygen from nitrates which means the nitrogen part is converted to gaseous form and leaves the water entirely.  

 

I've had my pepps for over a yr. I do have some smaller ones as well. Big female is about 8cm (breeding age) and pretty sure I have min 3 males in my smaller tank which I measured today.

59cm L x 1ft W x 40cm H

 

 

8cm is small for a breeding peppermint, they take closer to 2 years to reach breeding age and will usually be significantly bigger than commons.  Also I wouldn't keep more than 2 or 3 in that size, I have kept a pair in 60L that bred before but it was bare bottom getting daily poop vac and water changes.
