I've been keeping track of my tests, they don't look great and this is why I am trying to get a better test kit and get this water quality in shape. Suggestions would be greatly appreciated.
Oh and I've been fighting the Calcium numbers for a while. They slowly come down. I've not been adding kalk or any calcium additive and have been using IO for salt. But my coraline is growing just slow, I am starting to see it in various parts of the tank which is great.
Tank has been up for couple of years, moved once. Currently have a yellow headed moray eel, one lucky spotted hawk, zooanthids, button polyps, condy anemonie, gonoporia sunflower coral, candy cane coral, star polyps, shrooms, some macro algea, asst. snails, blue legs.
125g tank, about 15g more w/ sump.
2 175w MH 10k (ordererd a 15k bulb to see if I liked it, not here yet though)
2 96w PC 03 Actintics.
The day the tank hit 70 was a rough day, very very cold out too. The shrooms and condy were shriveled, once I got the temp back up everything has looked fine. I've got another post on the Nitrite problem: http://www.reefs.org/phpBB2/viewtopic.php?t=69287
I have no idea why the ammonia is like it is. Nothing in the tank appears to be dying off, and I make a point to not overfeed. Actually I only feed the eel and there isn't any leftovers. I feed the spotted hawk and condy about twice a month frozen mysis shrimp (1 cube). Dunno.
If everything looks good, but the readings show ammonia a trip to your fish store will give you a second opinion to see if your kit is giving good results
Looks to me like you have some ammonia and nitrites, have just gotten 20ppm or so nitrates, plus calcium is lowering. If the alk is not meg/l then it is low. You could try baking soda to lower the calcium and raise the alk.
The nitrogen compounds will be helped by increased plant life. Calcium algae like halimeda will also help lower calcium if you can get them established.
But a refugium with chaeto would help bring everything in line.
But then except for the increasing nitrates, things are pretty good as they are. So doing nothing may work also.
I would guess the test kits were old, and could have been old right from the LFS. I know you can give the batch numbers of salifert kits to the guy on the salifert forum on RC to get info. Get salifert kits as they are accurate, affordable, and available at most RDO sponsors.
