Ph

[pepperjack]

Meitzler, the skimmer intake was easier and i think raised ph more.

That black collar is a 1 1/2" ferco without the hose clamps. It fits perfect on the BM intake silencer. Then i stuck a 1 1/2 x 3/4 bushing on top of fernco. The 3/4 side of bushing was female threaded. I screwed a 3/4 male thread X 3/4 barbed fitting into the bushing then attached 3/4 clear tubing to that and for now it is running through a slightly opened window. I had ran it through the window as a test and it worked so good that i hate to change it. No fan or anything, it's just sucking outside air. Hope this helps

Apollothesun, Don't have pics of that but i'll get some. I'm gonna re-do that part soon since the skimmer intake does the job. I'm gonna leave the duct like it is and just reverse the fan to push hot air out of hood to outside of house. Don't know how much that would help your chiller. Hate to see you cut a hole through your house and not make a difference. I take no responsibility for mad wives

I did much the same with my BM 250 intake. I used a 1.5" PVC end cap which fit snuggly over the top of the air silencer. I drilled a large hole in it and then glued a 3/4" hose barb to the top and used some left over 3/4" pond pipe to reach the outside. For a more permanent air fixture to ventilate any room in your house, try this fresh 80.
Guaranteed to let enough oxygen into a room to burn a fire in an air tight retrofitted house.

Hey trido i kinda like that ventilator. I'm assuming it's got a fan built-in. Couldn't find any info on it. Something like that with a reversable fan would be the s_it. Definitely more professional looking than what i got rigged-up

Hello;

Ha, Ha --- well turning on the clothes dryer does exhaust CO2 laden air!


Your all right this time A+

Enjoy!

It doesnt hurt to run your skimmer outside but the effects on excess co2 are very mininal at best. Even high air volume skimmers are only pulling in a few lpm. When dealing with excess co2 we need to think in terms of cubic feet not the little clubic liters.
@ 40 lpm thats only about 1.5 cfm which is not enough fresh air to overcome excess co2.

Sealing a conopy and/or stand as tight as possible and venting it to the outside by 2 ducts one open and the other power exhausing will do wonders to elevate ph. Even a tiny power exhaust fan will give 20+ times the amount of fresh air being pulled by most skimmers. Surface area is probably the hardest thing to increase but is the most effective way to deal with excess co2, oversized overflows and plumbing do wonders for gas exchange.

Don's idea is the best I have ever heard and agree it would work wonders.

Hello;

It is a wonder someone didn't suggest a 50% water change back to back for 2-days!

You can turn your reactor CO2 down a little and use Kalkwasser to raise PH as the corals will grow faster -- "Somewhere, I read that."

I you do not have a dual chamber reactor --- make one --- buy one. The extra chamber of reactor media lowers the CO2 a little before it enters the tank. Or, add another skimmer --- move yours ---- pipe the output of the reactor to your skimmer and the air mix will liberate some of the CO2.

You can also run a sump with a lot of your favorite algae in it on a reverse light schedule to maintain PH at night as the Algae will use some or all of it.

DUCT it! Fresh air to your skimmer works well also. Everything will lower CO2 --- it may take more than one fix.


"If all else fails --- do a large water change!"

"I keep reading that"


Enjoy!

Sorry to hijack this thread....

But my problem is too much PH.... for several months I have been battling 7.5 ph which is too low.... And I think I am putting too much co2 via calcium reactor....... I tweaked it in such a way that i have a very low bubble per minute ratio....


Now my problem is within these three months or so..... my ph went up gradually.... and I hit 8.3.... and still going up....

Now I unplugged my calcium reactor because my ph is now at 9.3.......


I bet it is my probe.... but tested with a test kit.... the same reading.......


How do i lower it?


Thank you very much.... and sorry for the hijack.

Hey Don, have you acually witnessed this because I come up with the opposite results when comparing a fan blowing outside air to enclosed canopy vs skimmer pulling outside air. I had been doing both of these for months then recently turned off the fan that was pulling outside air due to summer heat. I use a ph monitor and there was no change in ph at all for the last 2 weeks. Still 8.2-8.3. Yesterday i disconected the hose from the skimmer and within 1 hour ph went from 8.3 to 8.22. This morning it was 8.1.
I realize a fan will blow more air than a skimmer will pull but seems the skimmer is much more efficient at raising ph with outside air.
