ANybody think that the flow rate is somewhat restricted by how much pressure is in the reactor? If you set a CO2 level where not all the CO2 is used up, there is a slight pressure buildup in the reactor which makes it for any small powerhead to overcome? Maybe that's why people use peristaltic pumps?
 
That sounds pretty reasonable, somebody should do a test and bump up there BPM like twice as high and see what happens to the effluent flow. This would be done by those who are using small powerheads to feed the calc reactor. Any takers? Hehe. Probably not, but if someone that hasn't setup there tank just yet tried it, I'd like to see how it goes. That might also explain why as time goes along, the flow slows more and more.

Peace,
John H.
 
There seems to be a slightly higher pressure for the reverse flow models versus the downflows like MTC or myreef.

Jorge, could you go into detail on this thread about the Mod(s) that people have reported success with? [/B]

Zak,

I prepared a document with detailed instructions and pictures on how to do the modification. I will send it to you by email.

rufio, exactly!!! it sounded like you didn't know, you do:)

How can there be any pressure in the reactor if the outlet is open, the ball or needle valves are on the inlet?

On the other hand there is pressure between the valve and the feed pump. alot!! maybe that's where the problem is, maybe just the constant back pressure on the pump slows it down. When I converted to the peristaltic, I removed my needle valve all together, no need since the pump puts out an exact amount.

Just my thoughts!

I just brought a Reeftech Calcium Reactor 10s, so this is my first piece of Marine aquarium Equipment.

I havent got my 70 litre jebo tank or stand as yet , but thats next on the list, when funds are available so that i can get it.

:)

Len, welcome to Reefcentral!! and good luck with your tank!!

Thanks for the replys...

What i plan to do when i get the 75 litre jebo tank is add a t connector between the pump and the spraybar that's over the trickle filter, the t connection will then go to the calcium reactor, but i'll have to find a tap so that i can vary the flow to the calcium reactor.

I was also thinking of maybe some how converting the inbuilt tickle filter into a refugium, but i'll have to work on some ideas as to how i will go about doing that bit of mod.


Regards from Len

Ps...I really should do a diagram to show people what i plan to do
with these two small mods..

I'd also like the document. A post might be more efficient.

JG1, you wont be disappointed, my drip rate has been 33 ml/min since I installed the peristaltic pump, it hasn't even changed 1 single ml/min.

Hooked it up yesterday.......thank god it finaly came because it's the first time my effluent has ben steady for 24 hours...lololol

Mine is running a little faster then yours...close to 40ml/minute, but I could care less as long as it stays constant.
 
Hey John,

My effluent dropped to 36ml an hour now. Can't do this anymore, I think I am going to throw the flag in and opt for one of these pumps. You got any pics?

You have to get one of these pumps ASAP!!!!

Thanks John! It looks great!!
How are you priming the pump? Do you have one end sitting in your sump? Do you need to attach a pre-filter to it? Thanks.
 
Priming a peristaltic pump?

Priming a peristaltic pump?

Do you need to prime a peristaltic pump? I thought as long as both ends (input and output) were submerged, then the pump will eventually draw the fluid in and push it out.

Peace,
John H.
 
I think you are right rufio173 :)
But how do you keep other things from getting into you rpump and ca reactor (pre-filter)?

I'm still using a minijet to feed it. I had two minijets in my AC300 feeding the Ca reactor and my Rowa Reactor. What I did was remove the minijet feeding the Ca reactor, and instead just T'd off the plumbing to my Rowa reactor so I have the one pump feeding both now. I opened valve on the Ca reactor about one full turn.
 
Hmmmm, I don't get it John. Why would you need to still feed it with a mini-jet? Doesn't the preistaltic pump feed directly into your reactor?
