    No problem. And like I said, that's what my corals are comfortable. I know every system is different. The .5dkh is more so a rule of thumb rather than a rule. You can raise it faster and be fine in some cases. That was just a happy medium that I noticed wouldn't effect the corals any time that I jumped that much.

    Having said that, there are definitely anomolies. Reeftopia has two CaRX but used to only have one. If it ever messed up, his alk would drop 2dkh and his corals wouldn't be effected too much. Who knows.

    But I have learned no matter what the state, make no sudden changes.. adjust gradually and most are fine.

    Good idea on the RO tubing. Need to figure out how to get from soft tubing to RO. Goodness know I have like a bazillion feet of it..

    Iíll show you my setup soon. :-) wink

    Only Reeftopia and Sanjay Joshi can get away with that. Both run higher nutrient and very stable tanks.

    That’s why I don’t run a CaRx. Not that they don’t work, but they can be a pain in the rear.

    When I put another GHL online with a KH Director...We’ll then have some great stability conversations. It will auto dose with failsafes dependent upon test results. All corrections beyond that will be done with one finger from my iPhone.

    IMO...the KHD is gonna produce far more stable results and led to some amazing SPS reefs. Can’t wait to get one online! It’s on.

    Automatic alk testers/dosers in five years will have just as big of an impact on our hobby as LED lights. They will probably become more prevalent than leds pretty quickly.

    No way! It’s just gonna get better and more precise. They’re here to stay.

    I mean they will be here to stay and have a huge positive impact in our hobby. Leds made a huge splash and have transformed how we are able to light our tanks. Leds aren't going anywhere any time soon, same as those testers/dosers once they get the kinks worked out.

    As much as I like LED flash lights and LED lights in general you’d think I’d switch already. I just can’t seem to leave T5’s. That even blanket of light hits every square mm of the coral tissue. Some of the absolute most stunning tanks are powered by T5’s. There is a reason why so many TOTM’s are running T5 fixtures.

    On the other hand, you see people like Sanjay and WWC converting to all radions. This makes sense if you have a huge tank or you have a warehouse to illuminate, but if you have a 18-24 wide tank, the cost isn’t all that much more. We now know from the study that BRS did that T5 lamps last a lot longer than initially thought.

    In the future, I think LED’s will continue to become the go to fixtures for reef tanks because of controllability and long term affordability. IMO, LED’s with T5 supplementation is the way to go. Or vise versa. I really like the new diffusers that the radions have. I hope they will continue to improve them and shrink their size.

    Metal Halides are done for the most part. The heat and electricity cost is driving people directly into Radions.

    Your last point was what I was going to say. When was the last time you saw someone with halide over their tank? Within a span of 5-10 years, they've all but disappeared. You find one every now and then, but not often.
