Hi Fencer

Please use same dosing
reduce the Bio to 4 drops weekly

Did you filtered over carbon ? if yes how much
and which changes ?
Redox is ok Salinity can be better at 34
but iám wondering why you MG and CA is so high ?

Hi Claude

Same dosing.
Dropping Bio to 4 drops weekly.
I will raise salinity to 34.

I use one litre of Carbon in a reactor. The reactor sits in the sump and only feeds back into the sump. In other words the carbon filtered water never goes in the main tank directly. The carbon reactor pump flows about 100 l/ hr. As for the Mg and Ca. My Mg has always been high and the Ca is due to the new salt being used. I could slow down the Ca reactor flow. But the Ca has remained constant( I have been testing this every day since I started using the new salt)

HI Fencer

which kind of carbon you use
what make your corals

Hi Claude
I am using Kent Marine Reef Carbon

I am not sure what you are asking, "what make your corals" please clarify
- I have 85 % sps in the tank mostly acropora sp(60%) but also have other sps species in the tank
-any recommendations?

Other notes
1. I have noticed my pod population has dropped drastically
2. I was moving some rock work in the main tank and caused most of the acros to start releasing "slime" into the tank. This was enough toxin released in the tank to cause signifigant tissue loss in the montis, birdsnest and echino. Pollioporas suffered tissue loss to a lesser extent. LESSON: never do aggressive landscaping in the tank when you have a lot of sps.

Hiya

Claude means what breed of corals etc

IH Fencer

hmm i did not know this carbon
it is pelltized or small granule ?

Please check the Ph swing and Po4 level of this carbon

you are right a massive landscaping can bring a loto f problems
check here also your Po4 level with a heat test

Hi Claude
This is a pellet type carbon...I suspect it is pH 7 or higher as is safe for reef and cichlid use. I checked it for phosphates and it did not show any trace. pH swing was also small. As a result of that moving rock around I did lose one SPS by STN others were damaged but have recovered.

Water tests to come on Friday/Sat. Here are some comparison photos:
