I'm not sure what you think the problem is here. But I only see 2 issues;
First, did you ever fix your salinity levels. Your first post said 1.008. That's almost a freshwater tank. Bacteria can't grow in there. Your low pH leads me to suspect low salinity too (or more correctly the low ph means probable low Alk
due to low salt mixture).
Second, the algae leads me to suspect you had your lights on during the cycle. I think you mentioned turning them off for a bit, but I can guarantee turning lights off will not remove or even slightly reduce algae already present.
So if you added a couple shrimp to cycle, and ammonia and nitrites are at zero means your cycle is finished. Nitrate is zero due to algae, no biggee.
To address to low pH and possible low alk
(you should test Alk
especially for a potential coral tank) add simple baking soda during next WC
. 1 tablespoon baking soda per gal
of water will raise Alk
and pH right away. As long as these is nothing in your tank the quick change is ok and excessive Alk
