    calculating co2 levels KH 17.8

    Ok will do. Sorry to labor the same question but if fish are in discomfort is it because of the co2 directly or the resulting ph drop? Sent from my iPad using Tapatalk

    calculating co2 levels KH 17.8

    Ok thanks ceg that makes sense. I'll carry on as I am then for a few weeks and observe the plants. If there are signs of low co2 I'll up the bubble rate. I think I was falling for the trap of getting too hung up on the readings. As a rule of thumb though what would be useful to know is if my co2...

    calculating co2 levels KH 17.8

    Thanks ceg, Well at 4 bubbles per second I drop about 0.5 ph in 2 hours however at that point the drop checker is still green. And I mean an emerald green not lime green.. His is why I was concerned as I see a lot on here with almost yellow drop checkers, distribution is fine. Reading is the...

    calculating co2 levels KH 17.8

    No fish in the tank yet but I have had numerous tanks for the past 10 years. At present the only other tropical tank I have up and running is a 100 gallon low tech semi planted tank with South American cichlids and 15 sterbai cory's. I've successfully kept high tech planted tanks in the past...

    calculating co2 levels KH 17.8

    Hi John. The water company initially said the KH is 320. Which threw me as I was expecting something on the 1-20 scale. They then converted it and came back with 17.8. The guy in their testing lab that I spoke to said 320 (I don't know what that is measured in) is the top level of hardness that...

    calculating co2 levels KH 17.8

    thanks guys. there are no ei salts or anything in there tanks just set up. im ignoring test kit results at the moment as i know im not getting 250ppm co2 its just thats what the readings correlate to. i know they are innacurate but didnt realise they are totally pointless ill leave it as it is...

    calculating co2 levels KH 17.8

    Hi All, im trying to work out the level of co2 in my tank. however the water here is very hard. ive been in touch with the water company and they said the water is KH 17.8. so on that basis im aiming for a PH of around 7.2 to have 25ppm co2. however when my test kit (so shoot me down in...

    pH profile during start-up

    Not to hijack but what is advised to use for the PH test. I thought test kits were the devil incarnate! Although obviously it is key to know what the PH is. I have just set up a new tank and will need to get a grip on the PH behaviour but at present have no way of testing it. whats the cheapest...

    CO2 regs from Malaysia

    Hi Andy. A few of us use that regulator, myself, BigDanne and ceg4048. it is compatible with FE's although mine is leaking. The seller has promised a replacement with all exchange costs covered by him i am just awaiting the arrival of the new one at present. Dan had a noisey solenoid which has...

    Confused, gassed fish without altering the reg

    possibly, stranger things have happened.. lol

    Confused, gassed fish without altering the reg

    cleaned diffuser = more co2 per second entering the tank raising the co2 level and lowering PH Improved co2 mist circulation = more of the mist dissolved in the water per second raising co2 and lowering PH Removed biomass = less co2 being used per second by the plants. i think you know the...
