Hi Bello, thanks for visiting.
Those are the common brown flatworms and the sixline is not helping. I just don't worry about them much anymore and vacuum out with some small airline tubing when I do my water changes. I also have AEFW, I saw the bite marks and blew a few bigger ones off some acro. I have not seen them for months, but I suspect they are still in there.
I had 3 montis that I spotted nudibranchs on and I removed each of them. So far no further damage.
That purple stylo has always had purple polyps. Even when I bleached it the polyps were bright purple. The ORA green stylo has never been fully green for me, just the tips. So far the Rainbow stylo only has green tips and dull purple polyps.
Filtration is a CPR Skimmer + 4.5 gallon hang on back fuge. I used to grow chaeto in there but lighting the fuge would always result in a buildup of hair algae and end up clogging the return area and changing the water level, which in turn would change the skimmer setting. I run it dark now, and I'm able to get a good full cup of brown skim every 2 days.
I also have an AC110 where I put my carbon and Phosguard. All HOB, so my water volume is very small. I dose 45ml of Alk a day, 20ml of Calcium, using Two Little Fishes two part.
I use Kent reef salt, for no other reason than it's very high in calcium and magnesium and the KH is near 9. I used to mix Seachem Reef Builder in my topoff water but I stopped, and then did not pick up two part dosing fast enough, which caused my KH to drop to 6.5 or lower. I'm hoping this is what caused some of the color loss. If not then it may be alk swings from my twice a day dosing, which means I will have to look into automating KH dosing.
I follow Biggles tanks as well.
