Hello Rob, like you I have several Orphek for my 160g. 1 atlantik, 4 atlantik compact and 2 OR3 bars 120cm. I discovered you as we have the same lights. To cut a long story short, I will take my chance to ask you some questions.Want to revive this thread and get a little bit more active. I can grow acros, quite good actually. I know there has been alot changes in the hobby in ways of methods. Some good, but most money grabs IMHO. Granted they work, but can you get the same results, with great husbandry, follow a simple method and very low over head and cost? Of course you can...if anyone have any questions... post them up
CHASING NUMBERS : when I started reeffing in 2019 I read that to have beautiful colors it is necessary to have low nutrients such as NO3 within 1 to 5 ppm max and PO4 within 0.01 to 0.05 ppm max. I think I’m not the only one who read this and this conduct a lot of reefer to chase these numbers. My question to clarify what exactly means « not chasing numbers » is : if my nutrients are STABLE with for instance NO3 within 5 to 15 ppm and PO4 within 0.08 to 0.15 I must consider that I don’t have to chase to lower these values right ? But if my nutrients keep increasing I must act right ? The same thing in the reverse, I my nutrients keep decreasing, I must act at some point ?
NUTRIENT LEVEL : in the reef it’s reported that the nutrient in the water are almost undetectable but at night a lot of food (phytoplancton and zooplancton) rise from the depths which I guess should feed the inhabitants of the reef. These conditions are quite not replicable in a reef tank even if many solutions exist to add phyto for exemple. What is your thought about adding phyto and other stuff like that in a reef tank ? Loss of money ?
Finally, my point is, as we can’t replicate all the conditions of a reef, isn’t safer to keep mid nutrients level than low ones if we are not sure to provide a constant flow of food ?
BACTERIA : do you add bacteria time to time to your reef ?
KALKWASSER : do you think using kalk is a plus in addition to other system of replenish (calc reactor, balling, two parts..)? If yes, do you know why ? By the way what is your model of kalk reactor ?
MIRACLE MUD : do you have clean-up crew in it ? Is it necessary to have sand on top ? Is it really mandatory to use Miracle Mud with a refugium ? Use of macro algae and light?
TRACE ELEMENT : do you add trace element ? How look your ICP about them ?
PRODUCTS : Do you use other products? If yes, what and why ?
Thanks in advance Rob.
I hope it’s not too much question.
Regards,
Benjamin.

, you will learn that trait the longer your in the hobby. If the corals are doing well, don't do nothing. If they're suffering a little bit, make incremental changes, if you do massive changes, they will suffer more. I never use Phyto, not going to say never..maybe used half a dozen times the past 10-15 years. I take a dive, because everything I read, but always the same results....ALGAE. Remember your just not feeding corals or whatever you're feeding Phyto for....in a glass box. You're feeding everything else and everything in the tank is opportunistic and eat it up, and if you don't have a well efficient nutrient cycling system, you're tank will most likely have bad results and grow a ton of algae or even crash. I can get away with it, because my tank is well established and what people call now a days good Microbiome, I call it DIALED IN
. So don't worry about Nut levels, if your corals are thriving don't do anything.
