Welcome to MonsterFishKeepers.com

The members of this forum have come together to share our knowledge and experiences of fish keeping. We want to answer your questions, offer advice and fill the galleries with pictures of the fish we have all grown to love.

We are a unique community of Fish Keepers who seriously take our hobby to extremes and the NEXT level. The majority of our fish collections include RARE & EXOTIC Species of all sizes, BIG FISH with BIG APPETITES and BIG TANKS. It's not easy for most people or other "regular" fish keepers to understand why we maintain this type of collection and spare no expense on this fascinating hobby.

Hopefully, through this site and discussion forums we can encourage the next generation of Monster Fish Keepers to have the same passion and love we have for the hobby and our Monster Fish .

As one of the founding members, I personally invite you to register and join us today. Currently you are viewing this site as our guest which only gives you limited access to view most discussions, articles and photo galleries.

      Actually, denitrifying bacteria do raise pH by increasing alkalinity. In nitrification, for every 1 mg of ammonia oxidized 7-8 mg alkalinity (as CaCO3) is removed from the water. In denitrication the opposite happens but not to the same extent. But I don't think that's the reason @jaws7777@jaws7777 tap pH is lower than his tank pH.

      My water is similar. It exits the tap around 8.6 and settles around 7.45 after aging.

      The pH of water will rise or fall after aging/aerating in a cup, bucket or aging tank for ~24 hours. This is because CO2 levels differ between water underground or in distribution pipes and between water at the surface. Water with excess CO2 will exit the tap at a lower pH and rise to higher pH after ~24 hours aging/aerating for ~24 hours. Water with relative lack of CO2 will exit the tap at a higher pH and fall to a lower pH after aging/aerating for ~24 hours.

      This is separate from what happens in a tank. In a tank, changes in pH are due to alkalinity, typically KH. Acids from driftwood, leaves, nitrification, etc. erode KH; pH falls. Coral, aragonite, limestone, bicarbonate increase KH; pH falls.

      Do you know you KH @Hendre@Hendre?

      Shouldn't the increase in carbonate hardness increase Ph?

      Yes. Thank you. KH increases; pH rises. :)

      I have relatively hard water and my Ph comes out at 7.8 and settles in at 7.6 after aging I assume it drops as the water is able to gain a bit of Co2.
      I keep several tanks some are planted and I add Co2 . I try to aim for 1 point drop in Ph to 6.6 I find that this is the sweet spot for optimal plant growth.
      I never fully understood how Co2 affected Ph till I started adding it. Or how fast Ph can rise once Co2 is driven out of the water.
      I used to stress of Ph and Kh and Gh,
      along with alkalinity when I was doing saltwater.
      So I learned how hard it is to try to manipulate Ph and try to maintain stability.
      Stability is the key, I never worry about Ph anymore as long as the Ph doesn't rise or fall to suddenly is all that concern me.
      I have some tanks that are 8 and some that are 6 some are 7. The tanks settle there on their own and are stable.

      Carbonate hardness right? There's 2 types of hardness but I haven't looked into them much

      Went to a SW shop today to look around and saw their reactor, a sulfur model, and discussed it with him a bit. He said it's a good piece of kit and this model was very good with an automatic hydrogen gas discharge valve.

      Main concerns for sulfur systems that he mentioned is that when flow rate is too high and it isn't fully cycled it can leach sulfur and there is nothing to consume it which can be harmful to fish. Also without good discharge or aeration hydrogen can also poison your fish which is a big concern.

      However once cycled it can quickly eat up nitrate, like water leaves at 0 nitrate, and once that is gone it consumes phosphates. Less algae anyone?

      Right, KH is carbonate hardness. The other is GH or general hardness.

      Thanks Mark! Good to hear from you. :) Connecting them in parallel/series was worth the extra trouble.

      Funny, I remember my tap water being pretty much the same before and after aging. I think I will check.
      no worries about hydrogen in the air? I'm thinking of the Hindenburg, hydrogen is not your friend.
