#1 If I use the socks it will be the Red Sea ones which are not felt and doesn't really filter much except for large particles. Also if I use carbon in a media bag should I put it before or after the fuge?
I don't use carbon as it effects my Kole Tang.
When I did, I had it in the return sump section, this was after everything. I don't think it matters.
#2 Why would it alter the cycle, most of the bio-media I mentioned are inert (or supposedly). I would expect it to speed up the cycle with more surface area for the bacteria to grow. Reason I didn't add any at the beginning was that I was reading a lot of bad press about them leaching AL and I have never really used bio media in my previous setups as I did the min 1lb/gallon rule but now I am using like 1/2 that. Also do you have any recommendation as to which bio media would be good (MP, Matrix, Spiroax, Brightwell)?
I don't know what these materials are made of, I too have heard some of these will leach things, mostly unwanted stuff. If its unwanted there is a reason beyond my knowledge as I am not a chemist. I pulled my Brightwell blocks and following ICP tests did reveal a drop in aluminum, and tin. So I say no on the Brightwell.
But my reasoning is I have always understood that you want all the rock sand and other bio-media in the tank from the start of the tank.
This is emphasized by WWC, BRS, and their tank start up methods. I trust their information.
The cycle takes what it takes. There is no speeding up the process.
Gestation with humans takes 9 months, dogs two months, so why most people feel that bacteria can be altered time wise, I have yet to understand.
The bacteria has to be implemented into the tank and allowed to grow and reproduce.
This gestation process is somewhere between 14 to 21 days with adding the recommended amount of the product to the tanks water and media volume.
If you add additional media days later then the calculation is off and will most likely slow the process.
There are numerus threads here on R2R about stalled cycles or cycle issues.
Many (Most) of them have a common problem of adding more media, more ammonia, more everything and then the cycle is slowed or stuck.
#3 So I will start adding Cheato after the cycle and with a few fish since the bio-load will be low anyway. Any recommendation on fuge lighting, I was thinking maybe H160 or H380.
Yes after. I can't help you on lighting, I have only used the H380, so far it has worked for me. But I have never used another light for comparison.
#4 I was under the impression that I should not dose at all until I have corals and as there wouldn't be any uptake of the nutrients from dosing? Also shouldn't my baseline be when I start adding corals and not when there is nothing in the tank?
Yes that's a true statement to a degree IMO. When you see a drop in ALK its time to start dosing according to Triton.
That said I started right after my tanks were cycled. 1Ml a day, I figured (Overthinking) I might as well get the tank introduced to all the stuff in Core 7 right from the start.
This way when it came time to acclimate and introduce coral the stuff was in there.
Thus potentially causing less stress, than once again adding additives and disrupting the stability of the water column they were used to for a few weeks.
The other reefing rule of thumb is go slow.
There is stuff in the tank, trace elements and so forth, this is what your testing with ICP.
I feel one needs to know what the baseline is of the salt mix being used.
Say you wait and test three months after addition of livestock and dosing.
It comes back with high element reading on Cobalt. Well was that from dosing, coral, maybe the food your using? Or is your salt mix high in Cobalt from the start?
