  1. Fertilizers and Water Parameters
    Hi, Who can think of a way to dose liquid KH or alk buffer using a dosing pump? It's easy to find solutions (no pun intended) for marine tanks OR powders for fresh water tanks. But I've not found a liquid product for fresh water. My tap water is 1KH so I need to dose alkalinity buffer, or...
  2. Fertilizers and Water Parameters
    Got a new test kit in today to test both General Hardness- GH (permanent hardness) and Carbonate Hardness - KH (temporary hardness. I cannot for the life of me figure out what would be making my tank water so much harder than the tap water I'm adding. Any suggestions? Here is all the data you...
  3. Fertilizers and Water Parameters
    Hello everyone, I hope this is the right place to post this. I've been having troubles with my duckweed (I know its supposed to be immortal but I apparently found a way to kill it off). The only other plant in my tank is an Amazon Sword (some type of sword plant, not 100% that its Amazon). My...
  4. Fertilizers and Water Parameters
    Hey everyone! I've been trying to figure out how to best treat my RODI water after a WC, as well as the balance of fertilizers to use in my tank. I used to use Seachem for water treatments and fertilizing but it's just getting to be too expensive and I really want to be in control of exactly...
  5. Fertilizers and Water Parameters
    I am trying to keep my KH stable at 3 or 4dKH. I've heard that it is better to dose the tank's water changes with KHCO3 rather than NaHCO3 since potassium is readily taken in by plants whereas sodium is not. Any KHCO3 branded products that you would recommend to buy online? is ADA Brighty K...

    Hello, I have set up a small tank using a Fluval Flora kit (8 gallon cube). The substrate is Fluval Stratum and I have added some driftwood and rocks. I didn't like the kit's filter and CO2 system so I switched to an AQUATEK CO2 Regulator Mini and an inline diffuser from Glass Leaf Aquariums...
  7. Fertilizers and Water Parameters
    My question is in regards to manipulation of kH or carbonate hardness. My tap water kH is roughly 4, while my tank tests at 2 to 3. ( I have driftwood in the tank.) I use the API KH/GH drop test to test the water. I just began my pressurized CO2 injection and have had trouble obtaining optimal...
