Minh's 320 reef

That's one beautiful clam, how hard is it to keep up with the calcium demand and seeing it so large do you see your alk being consumed faster as well?
 
I got a very efficient Ca reactor. It is a GEO but with modification by myself. I can keep up with it fairly easy for now with this reactor and GEO Kalk reactor. I am not sure how easy it will be when I have a full tank SPS along with these clams but for now it is easy.
I use Cole-Palmer pumps for the Ca reactor and the Kalk reactor I can easily control the rate of both of these process.

I don't know much about calcium reactors but does it also keep the alk maintained as well? They sound good but I am just used to dosing two part.
 
Ca reactor uses CO2 to dissolve CaCO3 and added into the tank. CO2 escapes into the air or get neutralize by the base from Kalk reactor.

The end effect is adding both Ca and Bicarb and what ever impurities in the solid. I use coral ruble so Mag, Strontium and all the other micro nutrient that are in the coral fragments got add to the tank also. IMO, this is the best way to supplement large reef tanks. I go to the poor house if I have to use three parts additive to add Ca and Alkalinity and Magnisium to the tank.
 
The problem with Ca reactores is that the CO2 bubbles are too larger and pumps have problem with dissolving the bubbles when the flow rate get high. In order to cut the bubbles to smaller size I put in a capillary tube (flow restricter for RO filters) to the air line and basically put in the CO2 as a stream of very fine bubbles instead of large bubbles. I have to thread the capillary tube all the way to the main part of the loop circulation.
In the GEO Ca reactor there is a bubble counter that would prevent me from doing this. My CO2 regulator already have a bubble counter, so I switch the CO2 input and use it as output while change the output as CO2 input. I thread the capillary tube into this new CO2 input and able to change the size and frequency of the CO2 bubbles input into the Ca reactor.
Got it? :)
I know you don't have a tank now. When you need, let me know and I can discuss this further. Good Ca reactor is essential for large tank. I have never seen any Ca reactor on sale with this type of CO2 input. It really help getting the pH of re reactor down without problem with CO2 wasting.
 
I consolidated all my tanks over the weekend. I moved a few things into the DT including a large Red Haddoni and my purple base yellow tipped Magnifica. I change all the carbon and GFO. I hope there will be no chemical war between the anemones. I got 5 Gigantea, 3 Haddoni and a Magnifica. A few Maximini and countless Minimini. So now I got 3 systems going. A 30 cube QT, a 65 gal reef at the office. An of course a few TT if needed. All bleached and dried.
Here are the two new addition to the DT from holding tank. They were in the same tank for almost 1 year so I know there is no chemical war between them. Just not 100% sure Magnifica and Gigantea will be problematic. I have had problem keeping these two species together before but cannot be sure that it is chemical war.

i've never mentioned it before, but a week or so after I put my purple gig into cipro treatment, my white tipped mag I had for about 6 months started deflating. I only noticed this about 2 weeks after removing the gig for treatment.
The timing was slightly off but there's nothing to say i wasn't deflating during the night after introducing the gig. They were both treated with cipro in seperate tanks, but the mag died relatively quickly whereas the gig just hung on for ages.
The mouth of my 2nd smalled mag that I purchsed for about a couple of months prior to the gig started to go all loose maybe a few weeks further down the line, but i have this feeling it was the clowns that was harrasing it. They were hosting the 1st mag and when i took that out, they moved onto the small mag. I also treated the smaller mag and have only just put it back into the DT last week but in a cage so the clowns can't get to it. It is looking ok, The mouth is closed, but isn't as tightly closed like it used to be. The endless water changes and maintenance got to me in the end and was a factor in why I moved it back into the DT. It seems to be stable so I am just playing the waiting game for now but am fairly confident it will be ok. I have to say, I wasn't running carbon (but I am now). I'm pretty new to mags and gigs (under 1 year) so that could also be a factor.

Good luck, I hope your collection lives peacefully together, just thought I'd mention my bad experience...
