Hi all.
I have just filled my first marine tank. Its 625 litres and everything is in including sand, Marco Rock, salt, Eheim filter, wave makers and dr time one and only. I started adding 4 drops per gallon of Dr time ammonia as instructed by the label and I believe the ammonia has flown off the scale! After further research on this forum, it looks like there have been a lot of Dr Tims ammonia products with incorrect dosing instructions due to a formula change!! I'm fuming!! as I think i'm going to have to drain my tank (which has taken 40 hours to fill via RODI filter!) and a lot of moneys worth of salt, one Dr Tims 'one and only' wasted! I want to sue him! but anyway...
I want to check my options with you guys:
1) I am testing using an NT Labs test kit for my koi pond and the ammonia colour takes way longer than 10 minutes to develop, more like 25 minutes but when it does, its a purple colour. Is a reading accurate after 25 minutes of developing? Is my test kit not suitable for marine water?
2) If my test is correct and my ammonia is sky high...shall I just leave it in order not to waste the one and only, or do 75% water change to get it down to 2ppm, its probably over 10ppm currently.
Many thanks
