    I dont totally agree with the above post. If you have low lighting you cant have an excess of co2 and nutrients that causes algae. You can never have an excess of anything, the only time having an excess becomes an issue is if you bottom out of something out... i.e. you have 2wpg light, lots of NPK but your co2 generator stops working and your co2 becomed 0.... this will cause algae.

    You can use EI dosing with low light and high co2 or low co2 and as long as you overdose your nutrients and dont bottom out on NPK or co2 then you will not have algae.

    Excess co2 is not an issue in itself imo, but excess nutrients certainly are, just as the lack of one nutrient in particular is, imo. However I do not agree with overdosing ferts to be a viable solution to this.

    NPK dosing is designed to replace or replenish elements already found in the aquarium, which are depleted by the growing plants. The elements are already found in your tap water at varying concentrations, and thus users will always have varying results when trying to keep a tank algae free.

    What you are doing with overdosing ferts and using a 5x dose of excel every other day (saw this on another thread) is basically "burning" or "melting" away your algae problems by using the excel imo. It does not mean your tank is balanced. Since you are using a diy co2 source also, im willing to bet that if you stop dosing excel you will have algae out the whazoo. Thats because as I say, the excel isnt providing you with "extra co2", but rather melting the algae as it often does to other soft plants such as vals. Excel provides almost no carbon when compared to a diy co2 setup.

    I have only just started dosing excel and had "zero algae" I only dosed it when i forgot to change a co2 bottle and ran out of co2 so BBA caught on some leaves. I did 2 week excel treatment to eradicate and then carry on.

    The levels of NPK in tap water are going to be nowhere near enough to sustain a high light tank with co2 or a lowish light tank for that matter if its well planted. Why risk hoping your tap water wont bottom out of nutrients?? why not just dose NPK every other day to reach the target level ppm and then you dont have to worry about ferts.

    All you have to be concerned with is maintaining a stable co2 which can be helped with a suppliment of Easy Carbo or Excel.

    Default Balance Questions

    0 Not allowed!
    Thank you for the informative article. I have been reading a bit, asking questions, and generally attempting to get prepared to receive another batch of "beginner" plants. Previous attempts have failed.

    It is clear that I did not understand nor pay enough attention to the three corners you point out in terms of what is required for balance. I have to say that what you say makes sense. I did read in many places early on, about five years ago, in my hobby time about lighting and addressed that according to recommendations from forum posters and equipment suppliers.

    Assuming that I got it right in terms of my lighting I now need to pay more attention to CO2 and nutrients. Both of these parameters seem somewhat trial and error.

    In the case of CO2 that can not be measured directly without a very expensive meter and most are getting approximate relationship equivalents by measuring pH and kH. I had been paying little or no attention to pH and I did not know anything about kH. I have ordered a pH meter and a kH test kit to track down where my CO2 is, or at least the neighborhood. I have old pH testing chemicals and currently my tests using those show a pH of 7.8. I don't want to invest in the complexity of a CO2 generator so I am hoping I am OK.

    I had not done anything about nutrients for my previous plant attempts. I have ordered pots, substrate pellets, and substrate to make sure I add nutrients. How do you determine your level of nutrients and if it is too high or low? Once you determine that these are too high or are too low how do you address that? Too low, I assume you add some? Too high I assume you stop adding or do more water changes?

    You answered your own question on what to do if over/under on ferts. There are chemical tests for iron and phosphate (I have both but for different reasons!) You know about tests for nitrates.
    Knowledge is fun(damental)

    A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.
