My current set up in totals is 404 liters including tanks and sump (main tank 240 liters) the system has a DIY auto top off RO
and auto salt water change. The salt water change happens daily in small amounts and is 25% over 3 weeks.
Here are my perameters. I'm all set to do a 40% water changed! i did a 25% yesterday.
I currently have soft and LPS
corals with fish
Nitrate 40ppm!! (concern)
phosphate 1.0 ppm
( not happy about this either)
I'm not dosing anything for cal or mag or dkh
. Are those levels okay???? thats my main query even though the phos and nitrate are high...
I am vodka dosing (from 13/04/12 to date) to try and reduce the phosphates. I've always had trouble with phosphates. my nirtrates have always been below 10ppm. I'm really careful with feeding. Never feed too much and always rinse the food. mainly because I've been battling phosphates
The nirtate have shot up over the past week. I'm guessing from the acclimation of my copperband. I overfed the system to get the little guy to eat... after a week he fianlly did. I threw all sorts of sea creatures in there to get him to eat!
Whats the best way to get the nitrates down?? is a 40% water change going to shock the system too much?
Any advice would be great
