Ph

[beaujames]

What is the best way to raise PH. I have been testing for the last two years with regular test kits and I can not tell the difference in the colors. Tonight I got my Ph monitor going and it is 7.9. What can I do to raise this, my buffer also raises alkilinty, will that effect my calcium reactor?

I would also like to know what is the largest jump in PH that you can make in one shot.

as far as I know
the best way to raise ph .. is to take out the co2 of your water ..
with good water circulation
or
with kalkwasser solution

wait for better answers

525 that is about it. Here is more

Holy

Go with .2 pH in one shot and not more

That may be part of your problem, many STR produce excess CO2.

Thank you for the interesting link

please.. what is STR ??
not mention here

< streptococcus > for my dictionary .. is it ? :shock:

That should have been SSR or SSCR= Single Stage /Calcium Reactors but that is no on the list either DSR or DSCR, Dual Stage Reactors, have a second column of media the kills most of the CO2, so the pH intering the tank is higher. Your best bet, as you can see from the article, is to drip Kalk, as Kalk kills CO2. 7.9 at night, if that is what you got, is not to bad at all. Try to meaure the pH at lights out and lights on. This will give you the high and low pH of the day. Plant and corals take up CO2 during the day, so the pH is the highest well into the day. At night there is little CO2 uptake and actually CO2 input, as plants and corals give off some CO2, so in the moring it is the lowest.

Sorry I was so short, it was late

ok
thank you

you know, out of every time I have thought I'd had a PH prob, it was the test kit. And believe me, boomer has trouble shooted it quite a few times with me.

What should the high and low readings be? I assume the high should be between 8.0 and 8.3 which you see frequently publish at night with lights still on? What should the low be in the morning just before the lights are turned on?

I am struggling with pH and have the air ciruclation problem. Looking at adding an outside duct to bring outside air into the tank. Open windows raises my pH a minimu of .3 based on tests done so far.

Thanks.

 

[Boomer]

8.0 and 8.3 = Night pH and Day pH. You do not want it to swing more than 0.3 pH units between day and night. The lowest night we want to see is 7.8 and the highest day 8.5

I have concluded that I have too tight house, that is keeping the CO2 high in the house. Open the windows and my difference is .3. So, I am going to build a fan to blow outside air overmy my aquarium. Has anyone used inline duct fans for this purpose. I would like to benefit from any lessons learned out there, especially noise considerations.

Thanks Boomer for the info.

Thanks.

Sorry so late. I had the same problem with C02. I used clothes dryer air duct to bring outside air into the hood. Used a 4" fan in hood to pull the air. When it gets hot this summer i may reverse the fan. I also ran my skimmers air intake to outside of house. I feel this made the biggest improvement(bm250 pulls alot of air). PH went from 7.7-7.9 to 8.2-8.3

 

[Boomer]

Cool idea pepper But what happens when the wife turns on the clothes dryer ? Do you have it fixed so it does not pull in any of that hot air as it leaves the house ? And what about the air duct getting hot an heating up your line? Is that OK ?

 

[Curtswearing]

Boomer,

I think they just mean they used the same type of flexible ductwork.

 

[Boomer]

Ah, I see that now Curt thanks

I used clothes dryer air duct to bring outside air into the hood.

I read it as

I used *the* clothes dryer air duct to bring outside air into the hood.

{Curt walking away shaking his head thankful in the knowledge that for one brief moment in time, he was smarter than Boomer}

 

[pepperjack]

Yea, sorry Boomer, that was the type duct that i used. Man, sounds like you don't get corrected very often, lol. You go Curt.
The way I did mine was I cut a 2" hole through the house. Stuck a piece of 2" pvc through hole then glued on a 4x2 reducer on the inside then ran dryer duct to tank. Outside of house I glued another 4x2 then put a piece of a/c filter material inside the 4' side of 4x2 reducer to keep the bugs out.

 

[meitzler]

Pepperjack. What size pipe did you use to run to the skimmer intake and how long was the run. Based on this thread, I did a test run with 1 1/4" pipe and a 3" fan to a BM 250. It definitely is improving approximately .2 from 7.55 (L) to 7.75 (H) to 7.7 (L) to 7.94(H). I still need to improve .2 I am now trying to determine the actual size of pipe I need (2", 3", 4" pr 6") to run for a distance of 9' with 2 turns and the size of a fan if any. Any thoughts are greatly appreciated.

We all get and NEED to be corrected once in awhile The other day I killed someone's shrimp, as I left out the " . " in the math calculation for a dosage of KCl. Big difference between 70 and 7.0 :lol:

any pics? planning on doing this for the summer, dont want to upgrade my chiller. just gotta convince my wifey im saving her money by cutting a hole in the wall
