Yet another deficiency...
Hi all,
I was wondering if I could ask some advise of you all? I appear to have developed a deficiency of some sort in my tank... I've been to theKrib and had a look at the chart and it could be one of a couple of things... Boron, Ca, Magnesium, Manganese, Copper, Zinc or Molybdenum... I put 5 drops of Dupla Plant 24 in my tank a day, which is enough for 250litres and my tank is 200 litres... My sword plant's new growth is light green, has holes, dead spots and the leaf lookes all distorted (kind of like melted plastic) Also, the old leaves of the Aponegeton are going brownish/red and develping holes... I would have first thought Potassium - for the holes, but I add 1.5tps of K2SO4 twice a week... I add 2x500mg tabs of Ca, and I add enough magnesium to bring my level up to 5ppm... Can anyone please point me in the right direction?? My Fe level has dropped dramatically since I added my PH controller... It was at 0.5, now I am having trouble keeping it above 0.01... Could it be possible that b/c now I have brought my CO2 up to 19ppm (previously I think it was 9ppm) that the plants are using all the fertilizers and I am developing several deficincies at once? Does anyone else find that there is ALWAYS a nutrient deficiency of some sort in their tank? Do you think that it would be worth making some PMDD that way I can tweak it to my spec's? I.e. more Ca and Mg than the Dupla drops? Thanks all. Justin. |

Everyone is going to have an opinion on this one and several on this
N/G that know far more than I, however I'll share my recipe. First, I run well water, which may provide an especially high nutrient value, but I've rarely had a problem with a deficiency. I dose nutrients to my 15 gallon (25%) water change about every 10 days. 5mL Serra plant fertilizer 1.5 tsp Green Light Stump remover (NO3) to achieve 5-10ppm (cause I have a low fish load) 2 tsp baking soda for the KH to achieve 5-7dKH (cause my water is really, really hard) 1 tsp Epsom salts and sometimes I add "ph7.0" product for a low level of phosphates. and three Serra substrate tablets under my swords once a month. IMHO..... every case if different so don't follow my recipe exactly. You will need to test your water often for several months to get a feeling for the condition of your tap water and your tank's nutrient use (or accumulation) dependant on fish load, plant density, substrate, gravel vac method, ect, ect. Start out testing once a week. Once you balance the environment.... once a month? My Aquaria info & pics at: http://www.geocities.com/spiral_72/Spirals_page.html |

This may be fine for a 250l tank but it really depends on how much light you have under the hood. Perhaps you should be adding about 5ml 2-3 times a week. My sword plant's new growth is light green, has holes, dead spots and the leaf lookes all distorted (kind of like melted plastic) Also, the old leaves of the Aponegeton are going brownish/red and develping holes... Starving plants,,,,up all your macro nutrients drastically. I would have first thought Potassium - for the holes, but I add 1.5tps of K2SO4 twice a week...

Yes. Add more ferts. Try to bring the co2 up even higher....30ppm. Does anyone else find that there is ALWAYS a nutrient deficiency of some sort in their tank? Do you think that it would be worth making some PMDD that way I can tweak it to my spec's? I.e. more Ca and Mg than the Dupla drops? PMDD is a good idea, every tank's needs are different. If you follow Tom Barr's recipe its virtually foolproof. Throw all the nutrients your plants will ever need and then do a LARGE water change over the weekend to reset the tank, best damn technique for growing aquatic plants ever -- Kind Regards Cameron |

Thanks for the tips guys!
I will do what you say and dump a heap of ferts in today and then do a 1/3 water change tomorrow. I really appreciate your advise! Justin "Dogma Discharge" wrote in message ...

It sounds like your plants are running out of everything now that they're growing fast with the CO2. I'd guess you're short on N,K, and Ca++ at the minimum. But don't try to spot-fertilize for deficiences. Add everything your plants could need. Duplaplant is supposed to be a very good fertilizer. I'd guess that you just need to add a lot more of it to get your iron above 0.2 ppm. Once you're out, PMDD are a good idea because they're cheaper and a bit more flexible. Also, use KN03 and a touch of KH2P04. You really only need K2SO4 for a tank with a heavy fish load that already has adequate nitrogen and phosphate. Tom's Estimative Index article explains the generous nutrient/big water change method Cameron is talking about. It's a brilliant and very simple idea that I've recently started trying to use for some of my more challenging sunlit tanks. The article is at http://www.barrreport.com.

Thanks for the response Elaine!
I looked at the BarrReport web-page and the article that you mentioned... It was slightly confusing I must say... But what I basically got from it was that you put in the amount of ferts that your plants would take up as a maximum and then accompany this with large water changes... i have also boosted my CO2. I think I may need to pull back a bit on the K2SO4 though, unless I am putting in matching amounts of Nitrogen or PO4 ( that is to bring it up to the NPK ratio)... Is that right? I am going to purchase the Trace mix and make PMDD... The only problem I had with the trace mix I found was that the calcium was in a carbonate form... Is this ok to use? Or should I hunt around for one that has calcium as citrate or another form? Thanks. Justin "Elaine T" wrote in message m... Dogma Discharge wrote: "Justin" wrote in message ...

Tom recommends Seachem Equilibrium for Ca++ and Mg++ if your water is soft or you're using RO. You'll be mostly Seachem Equilibrium, trace & iron mix, KN03, and a touch of K2P04. Seachem Equilibrium provides potash too, so you don't need to dose with K2S04 if you use it. Do you know about gregwatson.com for PMDD supplies? Plantex CSM+B at the regular iron is working well for me. -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |

Thanks Elaine,
Had a look at the seachem website and Equilibium appears to have what I need, great idea. The only down side is I want to move to discus, but most discus here in Australia are bred in 'normal' water, not the soft, acidic type so I should be fine. Unfortunately, due to all that has gone on in the world recently, we cannot bring some chemicals into australia, so gregwatson is a no go for me... :-( The main fert I am having a problem obtaining is KNO3... I can only get it from the rural area's of australia (about a 2 hour drive) and in 25kg bags. it is cheap (AU$45.00), but it's going to be a bit of a pain, but maybe I can sell some of it off (if anyone in Australia is interested??). I think that you were right with the Dupla... I have a feeling the drops were calculated for a beginning dose... I will go today to purchase the trace mix and 'roll my own' fert... Give that a go for a couple of weeks and see how I go... Thanks for all your help. Justin. "Elaine T" wrote in message m... Justin wrote: Thanks for the response Elaine!
