ph controller

  1. Equipment
    So I am planning on installing a CO2 system on my established 90 gallon planted aquarium and the biggest issue that I am running into is making a flow chart for a timer to shut off CO2 at night and a pH controller to help maintain a specific pH range and for monitoring purposes. I think the...

    The API pH test from the master kit shows my evening pH (without Co2) as higher than what my new Milwaukee pH controller shows. I calibrated the controller before use and did a test in the 4.0 buffer last night (controller was dead on with the buffer). The pH meter was showing 7.2, yet my API...

    I'm new to CO2 and will be adding Endlers, RCS, and Amanos shortly to a newly started 50g, gradually of course while it cycles. It's dawning on me that CO2 is by far the most dangerous aspect of fishkeeping, where a simple mistake or fault in a number of systems can quickly kill your entire...

    Howdy everyone. I have a 55gal tank with an Eheim 2217 and a hydor koralia 240 for flow. I'm finally at that point where I'm ready to undertake the CO2 addition. I try to buy solid equipment for my tank, so I'm asking for what has worked best for you guys. I can easily DIY stuff, so if that's...
  5. Fertilizers and Water Parameters
    Hello, I have just purchased a pH controlled pressurized CO2 system for a new 75 gallon planted tank that I am setting up and I have a question that I cannot seem to find a definitive answer to. Optimally I would like to have a final tank pH of 7 and a CO2 level between 20-30ppm. Can I get to...

    I have a 40-gal breeder set up as a planted, turtle tank. There is about 22-25 gal of water in the tank. I have a 5lb CO2 tank with solenoid and pH regulator hooked up to a diffuser in one corner of the tank. In the opposite corner, I have a CO2 drop checker. I just cleared up an issue with my...

    I am wanting to get a ph controller but the solenoid I have is normally closed. The one I was looking at is milwaukee MC122. I want it to shut off the gas if the CO2 gets too high. Will this work for my set up?

    So I have had a pressurized CO2 setup for a while, I've been running one on my 55 gallon tank for a year and a half. Unfortunately I've gone to college and had to down size to a 10 gallon tank. So now I'm playing a game I've never played before. I was running so many BPS on my 55 that I couldn't...

  11. Fertilizers and Water Parameters
    My PH and CO2 levels fluctuate a lot from morning when the lights go on to evening when they go off again. PH swings from 6.50 to 6.25, but CO2 seems to be the bigger fluctuation where it takes a few hours into the day before it reaches optimal levels (Drop checker goes lime green). Would it be...

    I recently bought a PH controller that I want combine with a Drop Checker to measure CO2 in my tank. In order words: replace the PH reagent in the DC solution with a PH sensor. I remember seeing a prototype drawing for this, somewhere in these forums, but I can't find it -.- Can you help...

    After some years of keeping fish and struggling to keep my plants the way I wanted them to look, I have decided to invest in a pressurized CO2 system. Because I wanted something "ready to go" and easy, I invested in the Red Sea Co2 500 deluxe system with a solenoid hooked up to my pinpoint pH...
