Official: Masterflex Calcium Reactor Setup Thread

You could try to do that but it likely won't solve the issue, it may make it worse. There are really two different problems that can cause this. One is a leak but if you are pushing I doubt that would be the cause. Some reactors that have effluent output on the piping and not on the lid of the reactor can trap air. The simple solution is to plug the stock effluent output and pull effluent from the lid. There is little reason to try and recycle the co2 like some manufacturers are doing. If the gas doesn't dissolve on it's first go around it likely won't ever dissolve.

If it is just some small bubbles it's no big deal. If it is a large amount of trapped gas I recommend drilling the lid and pulling effluent from there.

I apologize in advance if the information I am looking for is already on this thread. I would like some feedback on using kalk dosing alongside a calcium reactor. I had started with kalk dosing for a while with approx parameters of 9 dkh with calcium at around 450. Then I added a calcium reactor and stayed within these numbers but then relatively quickly my dkh fell and my calcium went higher. My question is what is the relation between these two components and how do I approach the balancing act? When I read the D&D relations between alk and cal they seem to make sense. I don't understand what I am supposed to aim for and how to go about it? My corals seem happy although a large monti seems unhappy. My acans are bulging with joy,my sps seem relatively happy,my numerous fish (40-50) in 400 gallons are healthy.

I use both on my system, in fact I just re setup my kalk reactor. I have not really encountered this issue. In a very high demand tank I believe this is the way to go. What numbers does it currently run at. I tend to aim for 8,420,1260+
 
Not sure where the leak could be as I use a master flex to push should I change it to
A pull method?

If you are using the masterflex to push, I would check the connections at the tubing on the Masterflex as well as making sure there are micro bubbles where the pump is drawing water from your sump. It could also be residual air in the reactor that wasn't purged out. To remove air, shut the recirculation pump off. Push the prime button on the Masterflex to bring it up to full pump speed and tilt the reactor back and forth to help guide the air to the outlet on the top of the reactor. The flow though the pump should push the air out of the reactor if the circulation pump is shut off. You might have to shake the reactor a bit to get any air out that may be trapped in the media and to the top of the reactor.
 
So I did picked up two 77301 digital brushless units from ebay for 200 each.

Seller is frost liquidation and he has three more units for sale. He will accept best offer of 200 shipped on these.

If anyone is interested
 
Now the main question.

I have a 90 gallon in my living room and a 60 gallon in my spare room.

Can I use one masterflex on the effluent to feed the 90 and the other masterflex on the same effluent to feed the 60 gallon tank.

Basically I am trying to use one reactor, one regulator and ine tank to run two independent systems.

I figured with two masterflex I can use two different effluent rates and keep alkalinity stable on both tanks.

Can this be done.

That's a good deal. Is it the 6-600 rpm version? I'm having problems finding that info
 
Nice. Wish I had the room for a separate controller and pump head. I have the 7523-70 which is the single unit but it's the slower rpm model.

I think it would be difficult at best. When you change the effluent rate you change the ph of the effluent as the flow through the reactor changes this changes the ALK of the effluent.
 
Say I pull 15 ml a minute for one tank and 30 ml for my 90 a minute

So total ml is 45 per minute . Does it really matter if I pull 45 ml from one effluent or two seperate effluent holes
 
No but each tank is going to have different usage rates. If you have enough patients, I suppose you could reach a balance point. But, one you reach a balance point for one tank, the other will be out of whack, then you change that one and the other goes out. You could probably keep getting closer to balance, but once demand in one tank changes here you go again.

Any chance you could put both tanks together on one system, i.e., 2 tanks one sump.
 
What if I store the effluent in a dosing container and then dose the elffuent from it with a masterflex.

Lol I am sounding crazy now.
