Tank has been going for more than 2yrs. Still having alage problems come and go... Ran into problems more than once from running my light to high. Recently had a high nutrients I couldn't figure out. Turns out my few year old swing arm refractmeter with the numbers worn off and arm sticking wasn't working right.... Duh. Its been @6 weeks running at the correct salinty and things are improving. I went more than 1 year without adding anything to my tank but in the last few weeks I picked up a few things that are doing well.
