dosing rant
Thanks Rev and Longnose!
So one big problem that I had with my last system was dosing, and maybe this is because I had largely used Calcium reactors before that. I disliked how the proportions could easily be messed up, if one of the pump heads got stuck on "manual" you were in the fast lane to an ALK swing, and the only way to know that you are dosing too much is that for some reason you can't get your levels as high as you want them, and oh by the way your pumps/UV sterilizer/sump floor are coated in CA precipitate.
Check this out and tell me if you think the UV was accomplishing a lot with this solid coating on the Quartz tube:
What it is supposed to look like:

So I wanted to go back to having my CA/ALK/Mg and trace elements largely added all at once and in the correct proportions, and what better way to do that than melting old coral skeletons that already contain those components (for the most part) and adding that effluent to the tank! Wait, that there is a CA reactor! So I went into research mode and settled on a ReefDynamics CMR250E. The build quality is outstanding, all top notch parts, PVC welded by hand in socal, and lots of features.
I have owned GEO, I have owned PM, and Korallin, and this unit is superior to all of them in features and quality. You pay for it a bit, but in this case, you get what you pay for.

It took a bit to get to me, and I am not a patient man, but once I got it and worked with it a bit, all was forgiven and I am glad that I waited.
While I am on that front, I also purchased a used Aquarium Plants CO2 Regulator (I will not use another one, for a bit more money, that thing is unbeatable), and a 5lb CO2 tank. Well, the Reg turned out to be broken, which I found out after waiting all this time for the Reactor :cry: and I decided to just drop the dough for a new one, and a 20lb CO2 tank. Luckily, the seller of the bad unit agreed to refund me, so it'll be ok.
If you are in the market for a CO2 regulator and want to be able to control bubble size, delivery, heck, everything, go with this guy. It is spendy, but man is it worth it, and if you use good check valves, it'll last for ages.

Also, when you pay for CO2 at airgas or wherever, check your bill. Almost half of the bill is usually the "filling fee" and a small amount is the gas itself. If you can fit a 20lb cylinder somewhere, you will have to fill it VERY rarely, will pay that filling fee much less frequently. So by using a larger tank, you pay for the gas more than the filling, and the larger canister will pay for itself within a couple years in saved filling costs (not to mention in convenience of not having to fill it often!).
