Yes keep to around 7-7.5
OK update for you.
I have been dosing a mixture of ProdiBio and Fauna marin from the start, just to recap
ProdiBio every two weeks
Bio Digest
BioPtim
My findings are that this stuff rocks, my mV shoots up after dosing, I tried an experiment and stopped dosing for 3 weeks, after the end of the 3rd week my mV had dropped to a day time average of 350-360mV. After 3 days of re dosing my mV was back up to 460mV. of course I can report cystal clear water and zero nutrients, and only a minor amount.
Fauna Marin
The balling method is amazing at keeping your ALK, Mg and Ca at a steady level, the GHL doser plays a big part in this as does the fluid containers making a clean holding device. I am not dosing enough Mg or Ca to say I am getting the full colouration effect from the Trace B elements, but I have noticed the draw of Ca is increasing so I hope to dose more of these two in the near future.
This brings me onto the other items I am dosing.
daily
Min-s 1ml
Amin- 2ml
Power trace 1,4 1ml
Power trace 2-3 2ml
Ok this is where I am not getting the results I hoped for. The Min-S and Amin are doing a great job at coral health and polyp extension, in fact I would not receommend anything else. As for the power traces I am getting mixed results. The concept of the power traces is to enhance the natural colour of the corals, this I can agree they do, although by stag horn colony is proving stubborn of shedding its brown layer but the more I dose i can see the blue pushing through.
The issue is, since increasing elements 2,3 which is the iodine and heavy metals, my glass cleaning has become a twice daily chore, the rest of the tank is fine, only the glass, so I can not push these elements any further.
The positive side is the colours are very vibrant but in a natural way, the negative side is in my tank I have to now do morning and early evening glass cleanings.
So experiment 2 is about to start, I am going to carry on with the Min-S and Amin of course but stop the power traces just for now and see if the colours fade, I think they will but I will then switch to Ultra organic, a more all rounder of the FM range of colouration products.
I have also started target feeding my Ecno and ricordea with Ultra minF and Ultra Sea Fan mixed with ultra Min-D, I never knew an Ecno had such a big mouth!!! Oh my! I will have to get a video of this for you all to see, this little frag had its mouth(s) open for about half an hour sucking in the microscopic particles. My torch puffed up like a football!
I will keep you informed.
