Should I raise the pH?
I have a densly planted 30 gallon tank with pressurized CO2 injection and 3+
watts per gallon. Some of my plants are beginning to look a little "drab".. Here some specifics: Temp: 72-73 degrees pH 6.4 (wait to raise) dKH 4 Nitrites 5 (or less) Nitrates 20 Any suggestions?? Do you think maybe the pH/dKH is too low?? Thanks, Troy |

Troy, seems like you have plenty of CO2, even more than needed. If
anything, reduce the amount of CO2, that will bring your PH up a little, aim for around 6.6 with the current KH, that will give you a CO2 level of around 25-30ppm, there's no need for more than 30ppm. But I'm sure that's not the problem with your plants, you have enough light, you have enough CO2.... what about the rest of the nutrients? Nitrates are good, nitrites are not so good for your fish, looks like the tank still needs to complete cycling. What trace elements do you add (flourish, TMG, PMDD...)? If you can, also measure PO4, that would likely be required with the amount of light you have. Fleet Enema is a good source of PO4 and it's easy and cheap to buy at the local pharmacy. The values you have listed are fine, I think it's the ones you haven't listed that are likely to blame. Give us some general info such as water change routine, substrate used, fertilizers used and a description of how the plants look, something more descriptive than "drab" if possible :-) Hope that helps Giancarlo Podio "Troy Bruder" wrote in message ...

Actually, I do VERY little...
I change approximately 16-18 gallons every 10 days.. I add 3ml of FloraVit to that new water... That's it... I'm considering a PMDD, but I'm not interested in "mixing it up myself", so I'll buy a pre-made mix if I can find one (Greg Watson's?).. Troy "Giancarlo Podio" wrote in message m...
