Hello again. RO Water is pure water and if added to a tank of water with the readings you stated, it will dilute the kh and gh, which should lower the ph. Not really pure water. Close, but not pure... pure water would be distilled water. Although KH and GH are related to pH, that's in non-chemically...

Hello again. See what I mean weird the Hardness is going down to good soft water perimeters but the PH remains high. Nop... that's normal... You see, RO water has a buffer capacity of 0... this means that even if you mix a little bit of acid, or basic water, the pH of the RO water will change drasti...

Hello. And don't forget one thing. By adding NaHCO3 (bi-carb) you'll also be raising the pH of the water, because NaHCO3 is a base. Most people think that KH (Carbonates and Bicarbonates) are the only water buffers. This is not true... For exemple, peat lowers KH, pH and GH, and that doesn't mean th...

Hello. I had a L15 for about a year or something. I gave it 3 weeks ago to a friend of mine. I believe that the color is normal, specially if the fish is stressed. My opinion is that you have 2 females. In pekoltia the males have well-pronunciated odontes in the back half of their body/tail. http://...

I'm saying this because I was alerted that there are several ways to gender your hypancistrus, and the most comum is the hairs in the first pectora...

Hello.

Hello. First of all, congratulations for the Forum... its great. Yet, I tried to search for something related to my question and found nothing (I believe it's a good sign for the rest of you). I have a 60 liter tank, in which I intend to reproduce (at least try) L260 - Queen Arabesque. I have a fema...
