its hip to be square....

Can you explain to me how the cubic water column of the pipe relates to gph of tubing.

You're doing this to me on purpose, aren't you? You already know that I am arithmetically challenged and not just a little lysdexic.

So, you tried the flow rate in a pipe calculator I linked to above. Let's say you were silly enough to input some test values of 0.5" for the internal diameter of the pipe and gave the pipe a length of 12". Answer: 9.4286 cubic inches.

Then we Google a simple query like: cubic inches in a gallon.

Google tells us there are 231 cubic inches in a US gallon. 9.4286 cubic inches = 0.0408164502 US gallons.

This should give you enough starting info to figure out for your size and length of pipe how much water can be flowed through it.

If I have misunderstood you or am not answering your question perhaps someone else here can chime in with a better explanation.

Corey I think 1/2" tube can handle more than 100 gph. A mag 7 pump has a 1/2" outlet and the pump is rated for 700 gph so I am pretty sure you are ok if you are trying to get 100 gph thru it for your reactor.

 

[biecacka]

Thank you Dave. :lol: I wasn't tormenting you but I now know how to if I should need to in the future!!
Steve I agree with you, does 100gph sound about right for carbon? I do t have it tumbling at all due to fear of it breaking up and "dusting" my entire tank

[SPotter]

I never paid attention to the gph going thru my gac reactor all I looked for was the gac tumbling. I've never heard of gac breaking up and "dusting" a tank.

 

[biecacka]

I thought i read if it tumbled it would grind itself up and that could be bad. Anyone else care to chime in? If I'm wrong that really solves my problem. :lol:

Corey

 

[SPotter]

a slight tumble is ok, but a rough tumble will cause it to grind itself up.

 

[dave.m]

Never heard of it either. The GAC particles soon get wrapped in a bacterial coat so no crumbling. You do have to rinse GAC off initially for all the grinding that occurred during packaging and shipping, i.e. when it was dry.

I usually just follow the manufacturer's recommendation for sizing a reactor and flow (pump size) to the system. I size the pipes to the pump inlet and outlet, e.g. if the outlet of the pump wants 1" pipe don't expand that to 1.5" or 2" pipe or you won't get the rated performance out of the pump.

Yea on my old 220 I used a BRS dual reactor fed by mj1200 but I switched it out in my new tank for a geo one. Fed off my manifold. Just don't want too much flow going through it is all. I got a "great deal" on larger pieces of carbon in a group buy that is really dusty. So I rinse it thoroughly.
Here is what the carbon looked like before I just changed it out, http://i333.photobucket.com/albums/m377/biecacka/FE27C00C-5DE4-4A40-AB78-DBB4C0F8B75C.jpg[/IMG]

If you look back a few pages when I was doing my plumbing, the one drain line had a dip in it and I really think that dip is affecting the water flow. One drain has a ton of bubbles coming out and the other drain nothing.
Gonna have to inspect it further

Getting ready to start setting up my calcium reactor. Any advice on regulator?
I plan on feeding it with my manifold...

Corey

 

[Newbie Aquarist]

The regulator from aquarium plants is the best and it has a lifetime warranty.

 

[hollback]

I've been using a Hydrofarm one since 1999

 

[biecacka]

Jason where did you get it from?

Corey

 

[hollback]

Indoor Gardens on the corner of Indianola and Morse.

Indoor Gardens on the corner of Indianola and Morse.

Have you guys been to reef systems coral farm in new Albany? I highly recommend it if not!

 

[biecacka]

Yeah go there from time to time. Not far from house very cool place.
Jason I thought you might got it there. Any particular one or do they only have one?

Corey

 

[nanoohio]

i visited for the first time a few weeks ago and saw that 900 gallon reef display and wow

 

[biecacka]

Yeah that is a sweet tank. I don't live more than 10 minutes away but I happen to live 1 minute from Phishy so I tend to go there more often due to convenience

Corey

 

[nanoohio]

Do they have a good selection as well? Might check it out next time I'm down there.

 

[Reef This]

And my other hobby......

Corey

Nice reverse C in the back there. Must of been a good one. =)
