    Ei method soft water?

    Hello everyone, friends. I have a question on my mind for a long time. 1st question = Does the ei method work in very soft water with 0 Kh - 3 Gh? Or will the ei fertilizer rates be too high? Have you tried the ei method in soft water before? If yes, can you share the tank pictures...

    150 ppm co2?

    Hello to everyone. Friends, my tank is kh 4- gh-6 My pH is 5.8 although kh is high Is this normal? I think the CO2 is around 150 ppm. There are no fish or other creatures in the aquarium. There are only plants. I've tested my testers many times and there's no margin for error. Calibrations...

    remineralise Ro water with 0 kh?

    hello, so i use Ro water and i would like to remineralise it with seachem equilibrium but I'm aware that this has no affect on Kh. so my question is can i use reminerailse my ro water with only sachem equilibrium even though the Kh will be 0? i use Ada aquasoil and my co2 is at 30ppm, i also...

    Why Advise A 1pH Drop?

    Hi Folks, I don't understand why a 1pH drop is advised when setting up a profile for injected CO2. For example, if the water KH is 4dH and the starting pH is 7.3, the CO2 concentration will be approximately 6 ppm. But, after a 1pH drop to 6.3, the CO2 concentration will be a staggering 60 ppm...

    Ideal Water Parameters

    Hi I have a 240l tank that I have now converted to a high tech planted tank. Ive decided to use RO water and remineralise as my tap water is terrible (about 60-80ppm nitrate and very hard water) and have been deciding on what parameters to aim for and so far ive settled on a pH of 7, GH of 6...

    What's the latest consensus on the effect of high KH on plant growth?

    Dear members, What I have read in various forums so far is that high GH values isn't a big deal for most plants and they grow just fine. There seem to be a difference in opinion regarding high KH values. My first question is what's considered as a high KH level? Mine is 9 dH. Is it high or...

    Another PH/KH/Co2 ppm Profile question

    LED lights are on for 9 hours at maximum 40% of their capacity. KH color test (with a Sera drop set), color change at the 7th and sometimes 6th drop, tap water is at the 8th. Water temperature 22.5-23C. These drop tests are not very accurate!! PH (Sera drop test set) 08:00 >7 14-21 ppm (KH7...

    Using the pH, KH, CO2 chart

    Hi Folks, I want to try to gauge the acccuracy of the pH, KH, CO2 chart for determining CO2 concentration in the typical (!) tropical planted aquarium with fish. As I understand it, this chart relies on carbonic acid being the only acid determining the pH of the aquarium water. But there are...

    KH Stability

    Hi Folks, In my tropical planted tank (including fish), I use RO water to which I add Tropic Marin Re-Mineral Tropic salts. I also add sodium bicarbonate to bring the KH and GH to 5°dH and 7°dH, respectively. In as little as 9 days, the KH has increased to 6.5°dH. When KH = 6.5°dH, pH varies...

    Should I use RO water

    hello UKAPS, I am a new member an have posted a short introduction in the new members section. In short I am in the process of setting up a hi-tech planted community tank in a Fluval Roma 200.But in the past have always done lo-tech tanks. Now I have a question about the hard water in...
