Hi jdieck:

Everything seems to be working fine, I will post the readings soon. One little issue I have been running into for the last few days, can't seem to keep the pressure stable on the right hand side guage as a result the co2 BPM keep on going up and down. I first thought that the regulator is faulty so replaced it, still same problem, so I changed the check valve and did a complete leak test the problem still seems to persist !! Now I keep on checking my bubbles every now and then and adjust accordingly. Any thoughts what the problem could be ??

This afternoon the BPM had dropped from 35 to 24 so I upped it back to 34-36 range but after few hours now they have gone up to like 50 I had to bring it down, this is just driving me nuts!!

What regulator are you using and what is the delivery pressure set at?

I am using Milwaukee MA 957 regulator and have set the delivery pressure 20psi

Try increasing the pressure to 30 psi and see if that helps with stability.
 
It took me almost 65 pages to get it right. Thank you everyone!

I couldn't for the life of me figure out how I was supposed to get a feed pump to pressurize my 1502. Here is the pic of the t off. It only took 6 pieces to get it right. LOL Anyway, my ph is now stablilized at 6.6 out of the effluent. I spent a few weeks (6) trying to get it below 6.9 without a pocket of air breaking my feed line suction.

One more question. Does it matter which line out you use for the effluent measurement? Dragon said to use the #2 but the Korallin manual said to use #1.

Thanks again,
Michael

Disregard the manual and use the bleed line for effluent flow. This reduces significantly the risk of running dry the recirculation pump.

I am extremely tempted to try this just to stabilize the effluent rate.

1. Will there be any problems with having less pressure behind the bleed line?

2. The Eheim pump has a strainer to prevent stray media particles from getting sucked in, so no junk can get into the pump or effluent line. Will I have any problems with anything getting jammed in the bleed line?

Thanks for the help jdieck, I appreciate your time.
 
Because your feed line is pumped rather than gravity, output pressure on the bleed shall not be a problem.
The strainer is basically good to prevent media grains to go into the pump but usually will not reach the outlet for the bleed line.
 
Hi jdieck...hope you doing good.

My Ca reactor is working ok but I am still facing the low pH problem in my DT. My fishes and corals seem to doing fine. After doing everything you suggested I am planning now to add a second chamber in the calcium reactor in an effort to raise some pH. Two questions:

1.My pH controller is set to cut off at 6.5 do I increase it to 6.6 or 6.7

2. Where do I get the second chameber from and which one do you recommend.

You do not need to change the controller set point at this time. Install the chamber and test the change in alkalinity in the DT, if any just make small adjustments. Although the second chamber may help add a git more alkalinity in reality is not a lot so wait until it is runing and asjust accordingly. If you are measuring the effluent PH in a cup then you will need means to measure the PH in the first chamber. Control from the outlet of the second chamber is not efective due to the extreme delay in response time. If your reactor does not have a probe sump for the chamber, you can easily make one to conect in between the first and second chamber (See drawing below)

I have never purchased a second chamber separately so I would not know which one to recommend although any chemical media reactor will do, Geo makes on as well as MRC or you can make your own:

I recently bought a 1502 used and was looking for threads on any mods that are done to this reactor but couldn't find any. Anyone know of any? Thanks
 
help setting up C-1502!!!!!

help setting up C-1502!!!!!

Can someone clarify which output is "output 1" and which output is "output 2?" I just inheritted one of these skimmers with no instructions...basically, here's where I am:

I have a 2 gal/hr pump feeding the reactor...once it filled up, i got all of the air out of the chamber, and then closed the output that is directly coming out of the cap of the reactor....I then tried to set the other output (the one that is coming out of the exit of the recirc pump) to 40 drips/min. When I did this, the valve at the closed output (on the lid of the unit) started leaking...does this mean i have to dial back my input to the reactor? And am I setting the correct output?

Secondly, I have heard people talking about dripping the effluent into a "drip cup." Is that necessary, or can i just let drip directly into sump?

any help is much appreciated - - - as i said, i dont have any directions and have not been able to find any.

thank you
 
ADW,

I've been using my 1502 for several years now. As far as I'm concerned, there are no mods necessary for this unit but a search on RC for the 1502 may yield several threads on tweaking it a bit. The only recommendation I would make would be to have as constant an input flow as possible to aid in tuning / keeping the effluent rate constant over long periods of time. I set and forget my reactor for months as a time. My setup is a 300G total water volume mixed reef with SPS/LPS and Softies. I feed my reactor directly from my return pump, although I've also tried an aqualifter pump and a small power head. I've had my best results with a valve controlled, 1/4" feed off my return pump.

Monty,

The output on the top of the reactor cover is output 2. I use both outputs in my system. Output 1 drips/flows into a small shot glass size cup that I also keep a PH probe in to control my CO2. Output 2 drips at a rate of ~5-6 drips per minute and helps keep any excess CO2 from building up in the top of the chamber. You do not need to use a drip cup. It really depends on how you will control your CO2. You could just drip directly into your sump and have your CO2 controlled by the overall PH of your tank. Others (me included) choose to control the CO2 by the PH of the effluent. This allows for monitoring both effluent and tank PH simultaneously (with two probes of course), to see the impact of effluent PH/drip rates on overall tank PH. As for your leaky valve, unfortunately, those valves are not of the best quality and cannot handle any type of pressure. Keeping it completely shut off would cause a leak with any pressure behind it. If you follow my suggestion of having both valve fully open and then using pinch valves to regulate the drip rates, I think that will solve your leak problem.
 
you got it - thank you

i like what you said about having both valves wide open - - ill pick up some new fittings tomorrow to control on the input side...this would seem to solve all of my problems, once chamber is full.

Disregard the manual and use the bleed line for effluent flow. This reduces significantly the risk of running dry the recirculation pump.

After experimenting, this didn't work well for me.

When I got a back up in co2 in the reactor, the effluent stopped dripping due to gas build up and the ph went up causing my ph monitor not to trip the solenoid when ph was dropping very low in the reactor.

The other "output" always put out water because it was part of the recirc. pump making the effluent a sure read.
