What do you all think? Do more folks lean toward the reactors or the dosing pumps and why. I have a cal reactor and it has been nothing but a headache and on a side note I still have to manually dose to keep levels. It just seems with the pinpoint dosing of a pump as a better method. Looking for input. Thanks
 
I have used all methods and feel dosing is much simpler to achieve stablity. Calcium reactors have too many moving parts. You can just increase the amount of dosing as your tank matures...only one downside of dosing, over a period of time salinity does go up.

really? I didnt know that and good to know. Guess you would just have to account that into wc
 
i think you have answered your own question. if yor looking for a dosing pump check out marine color. i just ordered one on wednesday. its a bubble magus without the name.

haha. For sure. Thats what started me thinking about the change. Thanks for the info. I'll have to check it out because the calcium reactor has to go. Figur3 I can sell 5he thing for 2hundo and get myself a dose pump.
 
Hmmm. Why does it keep doing that only in this thread (double posting)

And ai feel just the opposite, having first had a calcium reactor, then a dosing pump, I wnt back to the calcium reactor and have no regrets. Almost as close to set and forget as it comes.
 
I guess if I had a better cal reactor things would be different. These stinkin coralife ones dont bring in a consistant amount of water. I then wen5 for the aqua lifter pump mod and its still all over the place. I have now been looking at dosers and I guess comparing the BM and marine color pumps is like the comparison between the wp40 and the mp's or tunze aye. Anyone using any of these with some input (the BM or MC)
 
I started out using dosing pumps and then switched to a GEO calcium reactor and never looked back. It may take a little while to get the reactor set up, but once you get it dialed in....
 
Sounds like your having trouble keeping a steady drip rate. Is that the case? It does seem not that uncommon of a problem with calcium reactors. Some people are buying used peristaltic pumps off of eBay to get a more consistent flow through their reactors. I picked up one of these and it helped me get a much steadier drip along with using a slightly higher drip rate. Other than that I've been very happy with me geo reactor.

I would like to ask my reactor loving friends, what challenge did they face with dosing. On the other hand, I can name quite afew with reactors. Media batches are different. I have had issues where I could not get rid of phosphates while using calcium reactor. CO2 leaching encourages algae growth....lets hear a few demerits of using automated dosers...

When you start a sps tank? then add $1000.00 in frags. and you dose 2 part at first because corals are so small they don't use up calcium that fast. When they start getting bigger, and you want to switch to a reactor,aren't you worried about killing everything when dialing reactor in???
 
I have a large SPS dominate system, my reason for the switch is purely financial, going thru a gallon each of 2 part a week even using BRS gets expensive. 1200 for a new GEO with all pieces and parts will be paid back in a year or less and then I can spend the $ on some other goodies I don't need lol.I never had any issues dosing except using it up. I also have yet to have any issues with the CARX it did take a couple weeks to get it dialed in and I check drip rate weekly 100 ML a min is easy to check.

currently in the market, i think, for a reactor and doing research.

Perhaps a chemist can better clarify what has been explained to me,
is with a un-balanced two part, i.e. calcium cloride and soda ash you mix in power form.
the reactions in your tank send the salinity and other out of balance. and with large SPS loads - large dosing, large water changes are need to keep the tank properly balanced. And with time can get away form you any ways.
using a balanced a and b product eliminates the side reactactions and this issue. but at large loads they are EXPENSIVE.
again no expert, just the jist of what i have been learning. Hopefully one in the know can better verbilis, Or correct my understanding.
a calcium reactor puts in what the coral consumed as there natural usage.
largest issue as explained to me is the regulator. A high quality regulator with a dual pressure chamber, first and second stage for control eliminates a lot of problems. large contact with media and a good pump.

what other parts of the reactor are critical to reactor sucess?
