Tank been running around 3 months now since first added water maybe little over.tested ph occasionally for first 2 months but always 7.8 ph using api so stopped testing then just under week ago i added crushed coral in 2 plastic old filter holders inbetween baffles in sump in high flow area and finally installed skimmer and very next day tested ph and it rose to 8.2 and couple hours ago i noticed quite a few specs of what i think is light green coraline algae ( same colour, consistency as what came on back of obe my hermit crabs the other month when bought them.
So if it is coraline algae im guessing as the ph risen in the laat week the calcium/ alk/magnesium that coraline algae needs to grow/ develop it can take/ use from the water easier at the higher ph so i will have to buy some test kits for calcium/ magnesium/ alk minumum shortly i think.but maybe it isnt coraline and just another kind of algae idk lol
