Official: Masterflex Calcium Reactor Setup Thread

My 7524-60 is making some clicking noise when running and I think the sound is coming out of the easy load head unit, is that normal? The click is in rhythm along with speed adjustment. do you think lubing the rollers would make any difference?

Yes, normal due to wear of the flat piece on the head that connects it to the motor. I solved the problem with a few wraps of teflon tape to eliminate the gap
 
What exactly are you wrapping the teflon onto?

when you remove the head from the motor there is a metal tab that fits a slot on the motor shaft, the connection wears and gets loose over time, that is what makes the clicking sound as the rollers clear the tubing it "snaps" forward and makes the click.

the tape fills the gap and doesn't let it click.
 
Sorry if this is slightly off topic... I'm switching from a GEO612 to a MTC Minical. I use TLF Reborn (will put that in the larger 1st chamber), but was wondering what people would recommend for the 2nd, smaller chamber? Just a smaller media? Finally, does anyone have a copy of their user manuals? I tried contacting MTC but haven't gotten a reply.
 
Hi, eveyone...
Question I received a MasterFlex L/S pumphead PharMed HP precision tubing 25' 06585-15
From Fleabay. And Thankful received a full refund on it,
Cause the tubing is Solid like a rock.

Any chance on making it flexible again.. any tricks.. ???

So I bought an old fixed rate Masterflex unit to run my Deltec and it came with this style power plug. Anybody seen this before?

Here's the model number of the drive.

I called ColeParmer and they were clueless on it but were very helpful otherwise. Before I cut this and splice it with a regular plug, I wanted to throw it in here first.

Anybody?

Try putting a piece of it in a pot of boiling water for several minutes. That should soften it up.

Unless I am mistaken, you have purchased a pump drive and the plug you see is to be plugged into a controller that tells the drive what to do.

MNever mind I just double checked and I am wrong. It is a fixed speed pump. So I have no idea why the plug. The fixed rate is 6 RPM whch will therefore not allow for changeing the ml rate without changing the tubing.

How precise does the adjustment on the pump need to be? I found one that is adjustable from 0-130ml/min in 0.5ml increments. Do you think that one will work or is that not fine enough adjustment?
 
Can a Litermeter dosing unit so the same?

No. The LM pumps are not designed for continuous duty and their pumps divide dosing amounts up by they day. They don't allow finite control over continuous flow. Instead the pump a small amount broken up over the course of a day. Their slave pumps with the AC adapter could run constantly but they aren't designed to and don't allow you to control the rate of flow which is critcal. Essentially the Calcium reactor needs constant flow and you want to be able to slow the flow down to meet the needs of the tank. In many cases, a constant flow rate of 25-50ml a minute is needed. I have a 650 gallon system and run my Cole Parmer at about 25 ml/min but I have relatively low calcium uptake. A smaller tank may require even lower flow rates or higher depending on the calcium use. They key is being able to adjust that flow to meet your tanks needs and have it constant so that the pH in the reactor is consistent and also to avoid the effluent line from clogging.

Thanks. I'm now on a search for Masterflex unit.
 
Hey guys!

I'm still alive, however extremely busy at work. I will be resuming normal business hours mid next week and will be more active on the forums again!

Just wanted to swing by and say hi to my favorite reefers after responding to a couple pms that have been sitting in my inbox... for like a month.

Anyways, howdy :wave:.

Loving this setup. I'm currently using a 7523-70 but just closed the deal on a 7523-60 which has the more ideal gearing. Best part is I made an offer for 250 and we settled at 260. Score!!!
