tap into the plumbing?

The old ball valve is about half way open so I have plenty of room to turn it up if the flow goes to low. Also I have a maxijet mod in the tank so I'm not to concerned about lack of flow. I have a small jg valve to use for the reactor line. I figure the UV will need the most flow so I can adjust that at the tee-ball valve. The other connections require less flow so they should be o.k. pulling water away from the u.v.

Oh yeah, I used a 1/2 to 3/8 jg fitting for my reactor. That way I don't have to search for a 1/4 bushing.

It's a pressure line coming off the output of the return pump; believe me you'll have plenty of flow through the tees.

I'm done. Thanks for all the help guys. Everything seems to be working well. The flow through the U.V. is nice and slow and the flow through the reactor is fast enough for at least 60 ml/min output.

It looks great, but now we can debate about your reactor output! I would recommend (unsolicited, sorry!) as slow an output as you can keep steady, like a drip/second, until you get your reactor ph steady at 6.6-6.7. (If you're using ARM) A slower drip of lower ph effluent will actually help keep your tank ph from dropping. It's counterintuitive, but true. You can use a Salfert alkalinty test kit to check your effluent alkalinity; shoot for dkh25 or so. You'll have to wait several days until the media is completely settled to get an accurate effluent alkalinity test result.

The ph probe in the reactor is reading at about 6.9. These are the readings from last night: alk 7 dkh, calcium 300, tank ph 8.3. The bubble count is about 100 as min and the output is 60 ml/min. I am using kalk mixed in with my top-off water to keep the tank ph at an acceptable level. It has only been up and running for about 2 days. The tank was cloudy the first day and now it is clear. I think I had some effluent build up in the chamber because I had to disconnect it for a few days and the media sat in low ph water. I would never turn my nose up at free advice. There is always something new to learn. I am following the settings of the people on Reef Central who built this same reactor. Hopefully I can find the proper settings if I go slow enough.
