I set my salinity at 1.023 and by the time the it needs to be topped off its right around 1.025........
huh?.......no no......I have a water lines for max and min water levels...because during the summer and winter the rates of daily evaporation are different......
I have two marks...one at where the water is "supposed" to be or max.....and an inch down at min, at the minimum point which is the most water I can afford to loose before topping off is set to be at 1.025 sg.....which is about 24hrs of evap......of course I never let it go down that far.....just a bare minimum and for when the girlfriend tank sits so the sg doesn't go through the roof and RTN all of my SPS........
I don't have the room for an autotop off or else it would be at a constant level.....since I have to top off daily from jugs from the water store.....(I live in a apartment so I don't have the luxuries of QT tanks, RODI units in the garage, frag prop tanks....hidden equipment rooms and such), and want to minimize the topoffs to daily....it starts at 1.023....the evaped water increases the sg to 1.025......and the top off brings it back to 1.023..........no...I don't topoff with sw....that would mean every day it would go higher and higher.......
my point was.....if you don't have an auto topoff and you set your sg at 1.025 with a refracometer, by the time you top off it could be higher than 1.026.....which I don't recommend going over.
Yeah its my theory that the tank maturation process which takes up to a year sometimes is a BIG cycle that within it has MANY alqae stages.....sort of like levels.....if your tank isn't up to it.....that level of algae will take off and multiply......if your tank and husbandry are up to snuff it passes through it.......which could explain why some have major outbreaks of redslime or others with hair or bubble........your tank has just the correct params to grow that kind of algae and it thrives........sort of an evolution of algae per se.....I think of valonia a more advanced algae that say....brown which is easier.
level1: brown
level2: hair
level3: red slime
level4: hard radioactive green
level5: corraline
level6: valonia
for instance because my new tank is just over a year old....I have just the slightest...and were talking slight....problem with valonia....I suspect soon it will go away, due to the reactor and going BB now. And of course the beloved corraline algae is in there that can be used as a trump card to inhibit the above...usually comes into play about level 5....but these are my observations and how I like to understand the whole scheme of things algae wise.......
