ph leval

Conditioner doesnt usually affect pH levels... How big a water change did you do? What is the pH level at now, and what was it before?

Actually I've recently found that it might. I've experimented with water out of the tap. It comes out of my tap around 6.8-7.0 then I add API water conditioner and the test water noticeably changes from a slight green to a more blue colour, indicating that the pH is rising..

To the OP, you haven't stated what the problem with your pH is. I assume by the advice given by a shop that your pH is too high?? How high is it?

A few more details about the tank might be handy too, such as how long has it been running, what size, what its stocked with etc?

Re: ph leval - Level

And while we're picking on peoples spelling, you'd better read this as you seem to say alot a lot......

OP; can you please define "pH problem"? And I'd love to know which shop suggested it was caused by "not enough conditioner" because, unless you're topping up a tang/malawi tank with rainwater and are using some sort of packet-buffer to make the water harder, it sounds like a sales pitch for something you don't really need...

my ph is 8 my temp is always 26 degree I do water change once a week taking 20 litres out each tank and i put 5 ml api conditioner and 5 ml cycle. I have 20 tetras in there but what i did was put my new fluval plus 2 filter in i took one media sponge from my other thank and put in the new filter . I just been to fish shop he told me have the fluval plus 2 filter blower half out and half in the water on hi as it gives more oxigen is that a good idea.

Ps just lost 6 lemon tetras. :(

I don't know the exact dosage rates for the products you're using, but they seem overkill. I dose my 220L barrel with 5ml of Prime, and even then often add another 1/3 of water straight out of the tap when doing water changes. You might want to look into changing from the API conditioner to Seachem Prime, it might be a bit more expensive but you only would need to use 1/10th as much. And there is no reason to use cycle with every water change if your tank is well established.

As for the pH, yeah its a bit high for tetras, you could try adding some peat to your filter to help soften it. Do you have any driftwood in the tank? And is there anything like shell or limestone in the tank that could be making it so high? Another option that would be fairly cheap and easy with the small volumes of water you're changing is catching rainwater to use for the water changes.

Hi Caryl I lost a lemon tetra this morning and I went to lfs and took some water sample In they said everything Is ok accept the ph was 8 not 7 anyway I was out today and came home and 6 more were dead and they said It was due to lack of oxygen so I was told to raise up the fluval plus 2 filter spout half out and half in the water to give more oxygen and have the water flow on high.

Ahh, that's why we said run both for as long as you can. Chuck the old one back in there now and run them both for a few weeks at least. Hopefully that saves the day. Basically you've taken the good bacteria out and transfered a little bit of it to the new filter while expecting the new filter to colonise and be able to handle the bio load instantly.

If you put the jewel back in there now you should find that it all comes right again as long as the media in the jewel hasn't been dry for too long (or washed in tap water).

Leave it in there for a couple of weeks, or a month if you're uncertain. Oxygen is usually fine in your tank unless it's overstocked, albeit I'm sure your levels should be fine if there was water movement on the surface. Ph problems might fluctuate depending on your tap water, it could be high from the tap, but drop down after some time.

Did the LFS show you or tell you what your Ammonia and Nitrite levels were?

Edit: DavidR, link was good laughs.

I doubt it would have a great effect but water has a greater affinity for O2 than CO2 so high oxygen will drive off CO2 and drop the pH. Airation can be used to remove iron from drinking water if it is held in the ferrous (soluble) state by high CO2 as the removal of the CO2 will convert the iron to ferric (insoluble) and it can be settled out.
