      Hello,
      So the problem is, that my pH is always rising and settling in the range of around 6.8, but I fail to understand why and I hope you will clarify the problem for me. Let's get into details:
      I am running inert substrate tanks, which have the following parameters: pH 6.7-6.8, GH 5-6, KH 0-1, TDS ~125.
      My routine is that I do weekly water changes of around 20%. The water for changes is RO water + salty shrimp GH+ + Azoo Triple Black Water (which is basically a tannins and humic acids extract)+ Azoo Ph Lower, and I usually adjust the pH to around 6.0-6.2 as I want to keep it acidic, but the pH just won't go down lower than 6.7(to be exact - If I would add peat, or a lot of those acids, then sure it would go down lower, but after some time it always comes to it's usual 6.8 range). I also adjust the pH of the top-up water, which is RO + Triple Black Water.
      As I am adding a lot of acids into the water I thought the pH should stay acidic, unless there is something that absorbs those acids.
      So I did a test - I have prepared my usual bucket of water, re-mineralised it and adjusted pH to below 6.0 and let the bucket be. After around 24 hours I have measured the pH of the water in the bucket and, the pH was back at around 6.6. So it raised a lot. Once again I lowered the pH to below 6.0 using Triple Black Water only, and after another 48 hours the pH was again 6.8.
      So why is the pH rising ? I understand that with kH 0 there is nothing to buffer the water, but since I am adding acids into the water and there is nothing that could absorb them what causes the pH to raise ?
      Thanks !

      Hi everyone, I have spent some time searching (unsuccessfully!) for any threads set up to address how to naturally and chemically treat the more important water parameters. Obviously I'm not talking about temp, but the PH, TDS, KH and GH levels are the ones I'm most interested in. Now I'm country based so the only water I've got access to is R/W and bore (perfectly drinkable from the pump itself, no brackishness) which I have used for 4 of my 6 tanks (tropical and a few lower grade cherries). But I want to better hone in the water condition as best I can so any tricks to raise lower the above parameters naturally or if need be chemically. Or if anyone knows/finds a link, anything will be appreciated.
      Had put this in the pinned "Shrimps 101" but will try to delete it as it's probably better as a separate post.
      Being rural makes water choice difficult and some of the values I've tested are way out, hence why I'm seeking advice.
      Cheers all.

      Hey SKF peoples,
      I'm just mixing up my RO water with a combination of GH+ and GH/KH+ to keep tiger shrimps in. And I thought I'd share my experience, I gradually added the minerals and measured pH along the way and I thought I'd share the results.
      I note that the pH may change overnight after letting stand but I have been running a pump in the water to mix it well and aerate it so I doubt there will actually be any measurable shift.
      As you can see by the results, the GH/KH+ pushed up the pH a LOT! Does anyone else have this experience? I have achieved my desired water parameters in terms of ppm and GH/KH however the pH is unreal.. and this is not the first time this has happened to me either. However t is the first time I have taken the effort to document the fact.
      I'm planning on experimenting with adding a very shallow layer of the cal aqua labs black earth premium and monitoring the pH over the course of days.. expecting it to slowly drop...
      Any input is 100% welcome!
      love n peace
      will
      PS the initial drop in pH after adding the first lot of GH+ I understand can be explained (as I have read elsewhere) that when attempting to measure the pH of RO water using a pH meter the device can not accurately produce any result due to the lack of ions/conductivity in the water.

      Just found this guy dead tonight. Yesterday he was fine.

      Now i found another alive, but has discoloration and some stuff on him near the tail. Quarantined now.

      The rest seem to be doing fine as far as i can see.
      I have some hydrogen peroxide 3% and melafix in hand atm. Or should i not use either and get some better meds ?
