well i was so excited a month or two ago when my corraline started spreading to my base rock and glass and powerheads.
now, i'm noticing spots on various rocks, where the corraline is dying. i'm seeing the standard white calcareous patches that are left behind. i have this on about 4-5 rocks, each patch being about the diameter of a dime.
any ideas what could be causing this? the odd thing is that i am still seeing corraline spread to other new spots in the tank.
the only thing i could attribute this too, is the lack of vho light. since the corals are no longer in the tank, and this is essentially a fowlr now, i have not been running the vho super actinic's.
i figured i would cut back on the lighting, since the fish dont need it, and the green algae was flourshing. the green algae is in serious check now, but i'm worried this is also hurting the good stuff.
my lighting schedule for the last month has been NO actinic 03 on at 8:00 am, NO 10k daylight on at 10:00 am, daylight off at 6:00pm, and actinic off at 8:00 pm.
so i'm getting 12 hours of actinic light, and 8 hours of daylight. but they are both Normal output (40w each)
should i start turning on my vho's again? they are two 46.5" 110w URI super actinic white's.
also, i am still adding kents liquid calcium, once a week, one capful. (but i will humbly admit, that i still have not found a calcium test kit, so i dont know what the calcium levels are.) i also buffer with seachem 8.3 marine buffer.
any ideas?
