Lost a few sps. Adjusted my dosing pump to dose alk and cal mainly when the lights are on, since thats when consumption seems to happen, and then another dose just as lights go off, since it seems to really go up, at that point, and then drops off thru the night, (a trend ive noticed watching the kh gaurdian folks, i dont own one, yet, but i follow along, and that seems to be the trend with most tanks) i was dosing around the clock, and i believe the ph swing, thru the evening, was causing some issues, and effecting my sps, esp newer frags.
Lost a beautiful mari colony, and an orange passion.
And about a week later, my ora frogskin. But, things happen. Could have been worse. So far, getting great growth on the rest of the sps, with the adjustments. I try to keep my alk steady at 8.5, and so far, so good.
Current params, since i ran some tests tonite..
8.5 alk
460 cal
1370 mag
Nitrate steady at 10ppm
Phosphate at .015 on the ULR hanna.
Happy with the numbers. But not happy with the sps issues.
I also ran higher nutrients, for a long time. Struggled, as we all do.
My nitrates used to run around 25-30ppm, and my phos used to run closer to .050 before id do waterchanges...
I attribute the lower numbers, to the brightwell export no3, and p04 blocks! I added them about a month and a half ago. And my numbers steady lowered. Almost too fast, at one point.. (possibly the sps issue, also) but finally stopped, where they are, and have stayed here, for about 2 weeks now.
I feed pretty heavily... I like to keep the anthias healthy, and they like small bits, often. So, we feed lrs nano frenzy (no seaweed, and small pieces) 2-3x a day. And tdo pellets or hikari pellets, in place of one of those meals, atleast, daily. I also feed the corals, once, if not twice a week, directly. And broadcast feed like every 3-4 days. (Had some sun corals, and was growing them, but recently traded them into the lfs, for some stuff my gf needed for her tank!)
Also should also add, switched salts. Awhile back now, but im confident in my decision. Started with small buckets, and after the 3rd, bought a big one, because im impressed with the coloration improvements, and the overall health of the tank.
I was a IO reef crystals guy.. it was cost effective. But, ive had my issues with it..
And am now using red sea, blue bucket. Very impressed with it. I tried a few brands, during my quest for a new salt, and this one seemed best for cost effectiveness, vs quality, ect. Happy with it.
