Stumped on levels...

Using api tests. Ph is 8.2 ammonia nitrate nitrite are 0. Phos is very low. Calcium is 420 and kh is 7..how is kh and calcium both low arent they supposedly inversely related. Would that mean mag is off? Its a 50 breeder with 120 watt reef breeders fixture and two par 30s. Temp is stable at 78. 2 mp10s. I do about five percent water change a week. In my old tank i barely did any maitence besides one water change a month with the same corals and they thrived. Tank had t5 lighting.ive been slowly increasing leds they currently are about 45 percent. I also have a reef octo skimmer in my twenty gallon sump. Fish are fine. Sps wont grow, zoas are slow, rainbow monti dying and an acan. Lps doing great. How would i raise kh i have two part do i just dose alot??

 

up your 2 part dosing until you find that sweet spot.

 

Calcium is not low.
Perhaps slowly dose the buffer only, retest in a few days.
I would get a magnesium level as well.

 

Oops I thought ca said 320.....I'm a little off tonight. yes, SLOWLY does the buffer half.

 

I have a mag kit just looking for the instructions.. I'm sure I can locate them online.. That test is the worst though it feels like I'm making rocket fuel

 

Kh of 7 ain't that bad either.

Is there enough light? You mentioned 45%

 

I'm not sure haha.. When I started them I had them at fifty percent and bleached everything so I'm slowly ramping it

 

Oh, I see.

Wow, bleached em at that %? Are they high enough off the Tank perhaps?

 

There much closer to the light then they were in my old tank. And its wierd because one acan dying three doing well. 1 monti dying two doing well seemed to happen all at same time. I also have clam that is mid tank that is doing awesome. I feel like if there wasnt enough light it would be one of the first to go
