Tap Water Filter
I bought the Aquarium Pharm. tap water filter. It says it makes the perfect water and with a PH of 7.0 I put in the drops as it says but tested it last night and PH appeared to be 6.0 in the NEW water....... How do you figure how to get it up? Put in more PH drops and if so any idea how many? It says 30 electrolyte and 15 ph drops per gallon which doesn't appear to be correct........ Ideas? Thoughts?

what is the PH before you used the filter?

also is there a special reason why you are trying to change the PH because most don't recommend messing with PH levels cause they are hard to keep stable...

The tap water filter makes the PH nothing. You have to put in those 2 additives that came with it to give it the stuff it needs. A PH of 0 thrown in my take would wreak havoc to say the least...... Tap water is 7.6-7.8 and ph has always been high. I finally got PH in tank to normal 7.2 level.

yeah most aquarists tend to stay away from changing ph using chemicals, if you want a different ph you will need to start using distilled with trace elements and proper buffering which costs a lot of money but is the safest way.

a ph of nothing is hydrochloric acid by the way, i dont think the tap water filter does that...

What is your tap water GH, KH and pH before using the filter?

Sorry I can't help much, but right now I am paying for R/O bottled water for my changes, and I have to lug it up 3 flights every week....I was thinking of using this product......

DI water (this product claims it gives DI, not just R/O) should have a pH of 7 and a GH and KH of 0. You will want to raise them somewhat...also any trace elements you will need (Fe, Ca, etc) to keep your fish/plants healthy....

In the end, pH should be the last parameter you change after you make the other adjustments and see the new results.

Please post an update when you need to change the filter with approx water created.....I might want to get this....$30 initial with $17 refills online....

de-ionization filters get exhausted fast. You will need to replace them a lot.

It alll depends on how bad your water supply is....... I'm getting good results from it. First few batches i checked and water softness was like 0 and PH seems to be 6.0ish for some reason........ My tap seems to run from 7.0 last night to 7.8 or higher...... I had a high of PH of 8.4 in my community tank before most of these water changes and gradually brought it down to now 7.2 :)

I'm curious, other than the known high pH, is there some reason you decided to alter the pH? In other words, were you having some issues that made you decide to do this? I ask this because I have really high pH of 8, straight from the tap. I drip acclimate each fish when I get them so there is no pH shock, but all of my fish are ok with it.

My wife and I want a community tank with angelfish and some other fish that need a neutral PH. When it was 8.4 we were lucky we had the few fish we had survive aka swordtails and mollies. :) Once we get it under control we can get what we want and not throw money away in dead fish. :)

I read a thread the other day about angelfish. Here is the link. Although I don't plan on getting any myself, I found the thread very informative.
