Since last week's water change there are things to celebrate and things to watch carefully.
UNDER THE CELEBRATE CATEGORY:
1. I believe the doser worked well dosing All For Reef. My doser has 2 pumps but I only use one to dose AFR. The other is set up to dose plain tap water into a small jar. That way I know that particular pump is working and since I set up both pumps exactly the same, I can assume that the one dosing AFR is also working. I will know definitively after 1pm since I switched the pumps this morning.
2. I am seeing little dots of coraline algae on the back wall of the tank. I have not had coraline algae for years, probably when I stopped keeping seahorses and switched to regular IO from Reef Crystals.
3. The SPS are looking very good in terms of color and they are encrusting or have growth rings.
4. As usual the fish look good and are acting well adjusted.
5. I had added PhosGuard last week in the top basket of the canister filter and PO4 came down to .45 Hannah Checker or .5 Salifert. Last week I think it was over .8.
UNDER THE KEEP WATCH CATEGORY:
1. There are uglies on the sandbed again. They are not too bad first thing in the morning with just blue lights. Then they get really bad as the lights are just starting to ramp up mid morning but at peak daylight there are white clean holes in the uglies. If I had to guess I would think a light loving organism is outcompeting the uglies. So for that reason I am going to do nothing and see what happens.
2. The toadstool is somewhat retracted this week. It might just be a leather thing

as I know they do that sometimes but I am not sure.
3. I have been using a Fritz alkalinity test but I ordered a new Salifert to compare. Very concerning was that they were vastly different. Fritz has been reading Alk at 8.5 (this morning at 8) but Salifert read Alk at 11.8 which is much higher than I would like. Which should I trust? My lfs had recommended Fritz but I am leaning towards Salifert being more reliable as I have used them many times in the past to test other parameters. As you can see, things are ok but not optimal.
