Clues that a major pruning may be in order
I'm a bit denser than some, but eventually I know that a major pruning
is required when: * The camera has to be set two f-stops lower than usual to take a picture of the tank because it is so dark * It's 2003, and you find a species floating on the surface that you thought you got rid of in late 2001 (Water sprite). * You only tied one rhizome of Anubias to your driftwood. You break off two large rhizomes that had grown on the back side of the driftwood. Three large rhizomes remain. * There's a black shrimp hiding in the removed Anubias. You have never purchased a black shrimp. * There's Java fern growing in the removed Aunbias. You took out all the Java Fern 6 months ago. * There's Baby Tears growing in the removed Java Fern. You took out all the Baby Tears 3 months ago. * You cut 37 leaves off two swords, and they still look full. * You discover two new 8-inch swords behind the large swords while you are pruning. This all happened yesterday. At 2pm, I told my wife I needed an hour to clean the tank, then didn't finish until after dinner. I estimate that I removed 40-50% of the plant matter in my tank, and it still looks heavily planted. I'm hoping this solves the mystery of why the fert dosing that used to be adequate to promote fast, algae-free growth has recently seemed inadequate-I had far more plants than I had realized! Tom Barr's latest recommendations (the Estimative Index) are starting to make a lot of sense. |

Is it just a ghost or Amano shrimp that's been chowing down on java moss? Or a new species? It looks an awful lot like an Amano shrimp, with the same yellow stripe down the back, but the body is black. It is not a ghost shrimp, red cherry shrimp or singapoor shrimp, all of which I have seen. It is very attractive. I believe it is an Amano shrimp that has turned black for some reason. It looks healthy. The only shrimp that I have knowingly added to this tank are Amanos (two dozen) and Red Cherr (one dozen) I'm hoping this solves the mystery of why the fert dosing that used to be adequate to promote fast, algae-free growth has recently seemed inadequate-I had far more plants than I had realized! I know the feeling. Remember when I posting here about how I had to put 4 Tb of TMG a day in my tank, and people were suggesting I add Epson salts or calcium or iron, that the plants couldn't possibly need that much fertilizer? Well, I did a massive pruning, and have tried to keep things cut back since then. Amazingly enough, the tank is now fine with about 1 Tb a day of TMG. Thank you for the validation! I just couldn't figure out why everything had slowed down. You know, there's a definite progression of problems that lots of people encounter. Mine went like this: * Planted lots of plants. They grew fast for a little while, then stopped. * Figured out they needed Potassium. Added Flourish Potassium, plants started growing again, then slowed again. * Figured out they needed trace. Added Flourish, plants started growing again, but soon started to look yellow. * Figured out they needed Iron. Added Flourish Iron, plants started growing again, but soon slowed down again. * Figured out they were low on Nitrate. Added KNO3. Plants started growing real well, for a long time. LFS traded cuttings for ferts and fish and equipment. Life was good. * Finally, inevitable horizontal and diagonal growth fills in lots of nooks and crannies with plants, and you have double or triple the plant mass you used to, even after pruning. Now the ferts that were fine a few months back are inadequate again. Algae starts resurging. That's the stage I reached recently. Now I've got three full buckets of cuttings and I'm amazed that it all came out of my tank, which is still heavily planted! Again, Tom Barr's latest recommendation (The Estimative Index) is starting to look smarter and smarter. You won't keep hitting these plateaus. But you will have to prune a lot. |

inadequate-I had far more plants than I had realized! Tom Barr's latest
recommendations (the Estimative Index) are starting to make a lot of sense. What was that (the Estimative Index)? Is this the one you are talking about For a 20 gallon tanks I add 2-3x a week: 1/4 teaspoon KKNO3 2rice grain's worth of KH2PO4 5mls of Flourish and once a week after the water change 1/4 teaspoon K2SO4 That is as simple as you are going to get. Do 50% weekly water changes and keep the CO2 in the 20-30ppm range. -- Thank You Dominic http://www.dlink.org/aqua |

Here's the original article: http://fins.actwin.com/aquatic-plant.../msg00594.html In it he refers to a dosing calculator: http://www.csd.net/~cgadd/aqua/art_p...osage_calc.htm Read the article to grok what Tom is saying-he's making an extremely valuable point. |
