Hi
I have been battling with Green hair Algae issue in the past 2 months. The tank ( 50 Gallon + 30 Gallon sump but only about 15-18 gallon water in sump ) is 2 years old and never had a GHA outbreak. While the situation is improving, in the process ( i used Vibrant for about 6 weeks and i have stopped that ), I have lost 5 SPS that's been in the tank for 9 months. While I thought it's low nutrient , I decided to test the water with ATI, and the result is shocking. It shows quite a large amount of the following elements. Compared with the test 1 year ago, overall 79% ok on minor elements while last time was 95% ok
Silicon 1552 µg/l ( 95.05 µg/l )
Copper 2.13 µg/l ( 0.48 µg/l )
Zinc 9.60 µg/l ( 1.90 µg/l )
Tin 20.78 µg/l (0.48 µg/l)
Aluminium 7.41 µg/l ( 0.10 µg/l )
I just replaced the return pump with mostly PVC hard plumbing with one vinyl pipe. How should I tackle these? I have tested the RODI water as well, everything is 0.
