delteck 501 help

[boots]

hellow every one

I seem to be having troble with my ca reactor,deltek 501.
I set up the reactor 2 weeks ago.
I am now at a bubble count of 1 every 3 sec. with a ph reading of 6.90 to 7.00
the out flow is turnd down as far as i can get it with out the fitting for the ph probe leaking.but I am still having trouble getting the ph down to around 6.5.
any suggestions would be great


thanks boots

Never used a deltec reactor before but 1 bubble/3 secs sounds a little low. I'd bump up the bubble rate. I'm running just about 1 bubble/sec for my Geo reactor now.

I run mine at around 60 - 80 bubbles a sec and flow is just before a stream coming out ( i call it a broken stream ) This gives me a reading of 6.5 ish using Rowalith media.This is maintaining calc. levels of 420 ish and Alk of 8.6 - 9.0 dkh.

I have been running at these level on my old 225 gal and as well on my new 315 gal reef as well. I do find i have to make a few adjustments from time to time to maintain this though. Depends on your feed pump as well. By the way my probe holder leaked as well for the first while , although i was able to seal it up.

For all reactors keeping the flow the same and increasing bubble count will lower the pH.

Might find if flow too low, reactor will not keep up with systems Ca/Alk demands.

thanks for all the in put


in mucking around with it over the past few days i have been able to achieve a ph level of 6.51 ca 430 dkh 8.5 and no leaks looking good for now.

thanks boots

now that I have my reactor running like they say it should ph 6.5 inside reactor, i find that my dkh/ca levels have gone way up.
My ca is at 450 ppm/dkh is at 11 is this cause for concern I have been monitoring it for the past few days and it seems to be stable there.
Or should i back off my bubble count to 1 bubble every 2 sec. to bring the ph down so that it is not dissolving so much media
