fighting nitrates

Post  phantom on Fri Apr 29, 2011 9:57 am

so mine has been stuck at 25 for a while,do water changes and it never seems to help
so I was reading up a write up and they used seachem de nitrate.this needs to be in
no more then 200lph flows so I have it in a bag and set in my skimmer (compartment in the deltec mce600).
they also said that as a last resort you can do a series of water changes, one after the other or a
day between them which will bring nitrate to zero.

Many people try to reduce their nitrate levels by performing a series of partial (20%) water changes. This will reduce your nitrate (or any other chemical substance) levels, but it is rather inefficient if the object is to reduce the levels to near zero in the shortest period of time as possible, with the least amount of water. On the other hand, if you reduce the level of water in the tank to 20% of normal and then refill the tank to a 40% level, you have already reduced your nitrate levels by half.

If you then refill the tank to the 100% level, your nitrate levels will be 20% of the original level that you started out at. If, on the other hand, you reduce the 40% water level once more to 20% and then refill the tank, you will end up with a nitrate level of 10% of what you started with. Perform the 40% to 20% reduction once more, and you will end up with a nitrate level of 5% of what you started with. Just think about it for a minute. If you started out with a nitrate level of 100 ppm and used this method, your 100 ppm nitrates would be reduced, in a short period of time, to 5 ppm, which is considered, by most, to be an acceptable level even for corals.


so will try the water changes if this doesnt work.....and the cyno is back angry032

well stock levels didnt change for ages then in the space of three weeks they went up....
but at the same time unknown to me the skimmer had developed a fault and stopped
doing anything.I had just thought that it was some sort of cycle that had stopped the skimmer.
reminds me...can you get some of that cleaning stuff for I want to give the skimmer a good
service.
