As to your protest that math can be 'manipulated', in case you didn't notice, the only thing that's being manipulated here is the truth. For the rest of us, a jaunt over to the hardware Buy/Sell forum will tell you that my numbers are spot-on.

I'm not an advocate of either - there have been several replies from users of both methods that have indicated that they are perfectly happy with what they have. If I have to choose between the two methods in the future and have the money, I will probably get a fairly nice Ca Rx. If I don't have the money to spend, I'll get a cheap DIY 2-part. I would feel comfortable buying a used Ca Rx but I wouldn't want to build one myself or buy a cheap one just to save money. Besides, resale value of dosing pumps is pretty high so there wouldn't be much loss involved in switching over later. And if you are really trying to debate the fact that a DIY 2-part is both cheaper and easier than a DIY Ca Rx then I don't really know what to say... DIY isn't DIY when you compare the ease and cost of a DIY 2-part and the ease and cost of a DIY Ca Rx. It takes literally 10 minutes and intuitive knowledge to throw together a 2-part dosing system. That simply cannot be said about a Ca Rx. And somebody mentioned it before, but where you get the chemicals from, the pool (grocery) store or pet store, doesn't make it DIY. It's a matter of what people want, not which is better or cheaper. And who's to say that the numbers you produced in your setup is the setup everyone wants? Or even more realistically, what people actually setup? And the same goes with 2-part systems. Don't take it so personal - and try not to get so caught up on what is better. Snarkys reply below says it all - it's just preference. This thread, if nothing else, has proved that it really comes down to preference & budget.

I think tank size is the deciding factor. Smaller tanks, under 60 gallons, a 2 part mix is simple, works and very economic.

To set the record straight, the figures aren't mine. Unless you want to intentionally ignore jdieck's charts which he reposted again on page 10. Anyway, I'm out of this one. I wouldn't presume to argue with an expert.

The range of cost is so wide, that is why I added the second part so each one can calculate their own, and I mean the difference is not only between DIY Two part and a Reactor but within reactor systems themselves and even within DIY sourcing costs. Once you have your equipment estimates based on your preferences then just add the consumables portion. I bet it will be different for everyone and for every system.

Any way I could get a copy of that Excel file? I'd like to make the point to my friend that a CaRx is not the ideal solution for her tank, and it'd be easier for her to twaddle with the numbers on her own, so she can see it for herself.

i know nothing so i go by what i see the pros r doing.
75% of the pros with nice sps dominate reefs switched from ca reactors to dose 2 parts. reason: 70% low ph in the am. 20% too much equipment to hook up (ex. kalk reactor). 10% trying to reduce space. 0% switch back to ca reactor the # speaks for themselves for those that have switched back to ca reactor, pls post here and let me have it. |

I would like to see were did you get the numbers from, I doubt many with a 200+ gallon tanks would have switched back from a reactor.

true.
the tanks i have seen r from 58 gal to 180 gal. anything over 180 i agree that ca reactor may be a better choice. |

I'm sure if it cost too much you would be motivated to find someone local that can sell you 50# bags for cheap. A CA RX system that can legitimately keep up with a 200+ gallon tank won't come cheap either. I guess if you were still baking the baking soda it would be a pain .

Yea, having a big tank and dealing with water chemistry seem hard to maintain, I don't know how people does it with Part A and B/1 and 2 bottle supplements.

I have been dosing two part ESV for 12 years and have had no issues. I have been dosing a 65gallon and 30 gallon tank though. I think it woul db eexpensive to dose the 156 gallon I am waiting on. It may be somewhere between $250-400 for the first couple years and probably $500/ year after that. With thousands of dollars invested and not to mention the livestock. $400/year on the average sounds ok to me considering a dog costs plenty more than that to raise each year. A dog compared to a whole ecosystem seems like apples and oranges too. A lot more death can happen in our tanks. Anyway if water quality is the single most important thing in our tanks, I don't see any problem in spoiling our tanks. Now when things start to mature 2-4 years from now I may think differently and want to add on a Calcium Reactor or Kalk Reactor or maybe just dose Kalkwasser as well as 2 part.
The problem I have with everyone thinking it is ok to always dose soda ash/baking soda and calcium chloride is that eventually your ionic balance will be way out of whack and you will be wondering what happened to your tank. Don't know what that's like obviously and I don't think I want to know. I think in moderation it could be ok but from what I have been reading in Julian Spring's new book, it is not a long term solution. I think I will try the 5 galon buckets of ESV for a year and see how things go. More gadgets when the tank matures. If you get a doser for two part eventually you can switch that over or add on another pump for Kalkwasser to keep the costs down. If a few hundred dollars a year is too much to maintain water quality than I think you should rethink having such a big expense. Just my thoughts. |

Does anyone else use 2 part at this high a rate for this size tank? Is there any other reason why a tank would require this much to maintain alk and ca levels besides growth and precipitation? (wondering if I have a problem in the tank)

A 100 gal system that consumes around 1.75 dKh per day will use one gallon each of formula 1 every 30 days and formula 2 every 15 days.
If the system is heavy loaded with sps and clams the consumption can be as high as 3 dKh per day which will increase the consumption to one gal each of formula 1 every 18 days and formula 2 every 8 days.
