Need a Ph of 8,5'ish

Chill · Post by **Chill** » 20 Jan 2003, 01:34

Two questions:

Will a huge turnover (20 times an hour) and lots of airation (2 powerheads with venting)make it possible to reach Ph of 8,5. If not I will have to add chalk i guess.

How do I measure conductivity?

HI!

Well it will highly depend on how hard or soft the water is, but if you have a turn over rate of 20 times the volume per hour and you have venturi system you should get really close to the wanted PH!
You can measure conductivty with a conductivitymeter which consits of a sonde, you can find these in any good shop! It is a must have , more the PH one!

I have never used a conductivitymeter, and hounestly, isn't it a little over the top using one?

Hi chill...

I have been in Norway a couple of times and what I can remember is that your water are very soft and humid but maybe it depends where in Norway you live.
If it's like that you will not reach above 7,5 in pH only with airation and hevily circulation so you get the answer by your self...chalk.
In Sweden we normaly dont have that kind of problem because our water is normaly hard and have a pH at 8, so I use a conductivitymeter when I blend my tapwater with RO-water that I use to breed my catfish.

Make sure the fish you are buying have come from a ph as high as this in the first place. New fish acquired will otherwise die very quickly. From the ph you are trying to obtain I presume you are possibly looking to keep rift fish. In tanks were we set up biotypes like this we use coral sand to help mantain the mineral content of the water, in a mixed substrate.

@janne >>your water are very soft and humid<< i dont know about sweden but our water here is often humid too

Its a group of L-204 that I have, they are getting a new tank and will follow the Ph from 7,1 up to the target. If I do it steady and over 3-4 weeks I think they should be ok, won't they?

hehe, I was going to try very hard to not go there, but you beat me to it Caol_ila

The addition of some crushed coral in your filter would push your pH and kH up, and make for a nice stable water parameter for your fish. Can I ask what fish you are going to be keeping that requires the pH that high? I keep tanganyikan cichlids that spawn and grow out quite nicely at 7.8 -8.0, even though their endemic water source is more basic, (above 9).

Hi!

The problem with adding coral or any stuff in ther to bring the PH higher to what it is will also have an influence on the hardness and on the conductivity of the water, maybe to level a bit too high, which could cause eclosion problem for the Fry!

Have you try injecting O2 ( not CO2)...

I would also like to know what are the parameters of the water you working with...

The tapwater is at Ph 7,1 - KH >1º dH - GH 1º dH, so you see the values are good.

I have never had to add any addetives for "normal" tanks, it adusts itself.

@Janne

Do they have conductivitymeter at claesohlson?

Yann · Post by **Yann** » 20 Jan 2003, 22:52

Hi Chill!

Is this parameter right out of the tape system or coming from the tank already???

If out of the tape system you shall be able to bring it to a higher level with good oxygenation.

If already from the tank, a little bit of crush coral could do it!

straight from the tap

Hi!
So with a good water flow, venturi system you should be able to bring it higher without adding anything!!!

May I ask why you want a pH that high for your L-204? I?m quite new with plecos, so I?m asking because I?m curious. Do they need that high pH to spawn?

To be hounest bernt, I don't have a clue to what conditions they spawn in, it's never been done before

They have this kind of Ph where they come from, so after trying a bunch of ways I have now gone back to the drawingboard with a clean slate.

I make you laugh anyway

So it can be sometimes when you not remember the right word...but it was not so difficult, we use the same word in swedish...humus...
I hope my water is humid too...in other cases my fishes will not be happy

No they dont have any there, but you can find them here: http://www.makab.se
I have this one and it's very useful, both uS and pH and easy to use. http://www.makab.se/order/index.asp?cat=6
