Matthew Posted August 19, 2003 Report Share Posted August 19, 2003 can anyone tell me how long it takes CO2 to diffuse from the tank. My current level is about 300, I don't have any fish in the tank at the moment, and am wondering if anyone knows when this level will drop to a healthy level. BTW my daphnia that I threw in the tank seem to be loving it. Quote Link to comment Share on other sites More sharing options...
Blueram Posted August 19, 2003 Report Share Posted August 19, 2003 Matthew, Would not have a clue about when it will be safe. Haven't done all my research into CO2, but what type of method are you using to inject your CO2? Yeast and Sugar or have you gone high tech with a CO2 bottle?? How are the plants doing?? Have you put them in this set up??? Blueram Quote Link to comment Share on other sites More sharing options...
Matthew Posted August 19, 2003 Author Report Share Posted August 19, 2003 Blue Ram, My technical set up is carbonated water from the sodastream plus a fermentation canister. I had the plants in the tank and thought I would boost up the CO2 level to encourage rapid growth. I tested the water today (pH and KH) and assessed the level at roughly 300ish. The plants seem to be loving it, and are giving off copious amounts of O2. This makes my tank a little more interesting to view. Theres only so much excitement you can get from a bare tank. BTW your sag is looking good, already sending up new leaves. Matt Quote Link to comment Share on other sites More sharing options...
john1 Posted August 20, 2003 Report Share Posted August 20, 2003 Hi Mathew I don't know what you mean by "300". Fish can only tolerate a level of 30mg/l. 15 to 20mg/l is ideal. If you want to know what Co2 level you have in your tank, then download the Co2 calculator from my site. But, you have to know EXACTLY the correct dKH and pH. Input these values into the calculator and the reading will be the Co2 content. John Quote Link to comment Share on other sites More sharing options...

john1 Posted August 21, 2003 Report Share Posted August 21, 2003 Hi all OOOOOOPPPPSSSSS. Now it is working. :oops: John Quote Link to comment Share on other sites More sharing options...
Matthew Posted August 21, 2003 Author Report Share Posted August 21, 2003 John, I used the scale on pauls website, I presume these are the same. If I can just highlight though in my first post I said I did not have fish in the tank, only daphnia, and I was waiting for the levels to drop before adding fish. the plants are growing well though in the current environment, and my amazon sword has sent up a flower stalk, so something must be alright for the plants.

john1 Posted August 21, 2003 Report Share Posted August 21, 2003 Hi Mathew Ok, let us assume no plants. No danger then. But what does '300' mean? Thanks John Quote Link to comment Share on other sites More sharing options...
Matthew Posted August 24, 2003 Author Report Share Posted August 24, 2003 I presume it means mg/L. unfortunately I rather hurriedly looked at the website, and did not check all the finer details. Sorry about the delay in reply, my keyboard decided to go belly up Quote Link to comment Share on other sites More sharing options...
john1 Posted August 24, 2003 Report Share Posted August 24, 2003 Hi Mathew Now that we know it is 300mg/l then we can talk a bit more. If you had any fish in there, they would be dead by now. 30mg/l is the maximum fish can tolerate. Not plant, fish. John Quote Link to comment Share on other sites More sharing options...
Matthew Posted August 25, 2003 Author Report Share Posted August 25, 2003 yep, I know that. the levels have now dropped to around 20, so I put a couple of bristlenoses and an ottocinclus in the tank. They seem to be alright. I guess i will find out later if they are not alright. Quote Link to comment Share on other sites More sharing options...
john1 Posted August 25, 2003 Report Share Posted August 25, 2003 Hi Mathew If the Co2 of 20mg/l is correct, then it is almost perfect for fish AND your plants. Good luck John Quote Link to comment Share on other sites More sharing options...
