The blind leading the blind? I doubt they know much about allocation of carbon in aquatic plants. It's far more likely and far more significant than any other "nutrient". You are welcomed to chase your tail. I've stated the issue, I've also showed without a doubt that the excess or other...

BTW, you are in SFBAAPS Tackful? If not, join, cost nothing. It will help you out GREATLY. www.sfbaaps.com Regards Tom Barr

Anytime that works for you. They are diluted once you add them to the aquarium, so they are not really going to come out of solution easily. Do not worry about it. Regards Tom Barr

Well, make sure your initial assumptions are correct, and you have done some homework prior, this will help you figure things out much easier with much less time and pain. So read the good stuff, ask others, think about what types of test might answer that question well, and think about all the...

No, it's due to the fact that you had less total nutrients, not water column vs sediment. Plants do not care(pretty much all plants, even land plants), as long as they have enough from either location or both. Plants, aquatics and other wise, are opportunist. They will take nutrients from...

So as the plants take off, you notice, less algae? You should, this is a general observation that is universal, same is true for natural systems. So before, you often still have the same ppm's, maybe you now have even more? But no algae, so what in terms of the plants, is really different...

Myself as well, algae likely thrive where there's an intermediate distance level in the aquarium. Total disturbances, well, then you go from huge extremes, not much will live. Minor, not enough to "tip the scales", medium, enough to harm the plants just enough to have them grow, but not dominate...

Do field weeds grow in the established forest? Or only where's there's a nice opening? Takes a few years to get the forest really chugging along. Similarly, aquatic plants ....once they are chugging along and well established, dominate the system, much like a forest. If you cut the forest...

Concentration is still part of the dose. You should question everyone really. Since dosage is concentration X time, and there's not much left and not much time for exposure. Why does it have to be a chemical secreted by the plants? Why does algae not grow in the winter in many lakes? Temp...

Well, if you have a tank like this: I can easily adjust the light up or down and then measure the PAR with a meter(this takes 15 seconds). I also have 2 different light types, I have a HQI(I have not used it on this tank for 2 years) 150W MH, and a pair of 55W PC lights. T5's are even...

Well, minus green spot algae, PO4 limited tanks run pretty good IME. But, why limit PO4 to reduce the rates of growth? This really gets at the core issue, how best to management the growth RATES of plants, this is less about algae......... With less light, then I have little issues managing...

Do you think you could be going from NO3 limited, to PO4 limited situations? Sounds like it. So do you think plants are better able to adapt to low PO4, or a more critical nutrient like N? N limitation will retard growth a lot more than P limitation. There's a great deal of evidence for this...

If you add active carbon or do large water change= no allelopathic chemicals, thus there's the control. See any evidence that using activeated carbon or doign large water changes somehow...induces algae blooms? I, nor anyone else would suggest it does;) So this is a very easy test many have...

You can see the sintered disc behind on the left. So yes, those are CO2 bubbles getting blasted around. They show up well in pictures. not so noticeable in person. Tank is a lower light tank, 1.7W/gal, T5 light at 30" depth. ADA As sediment, EI type dosing. Good CO2, wet/dry filter, good...

Ebay and know/learn what you need. See LeftC's thread on dual stage regs, plenty of examples there, ask etc if this reg etc is good etc, then bid etc, often you get nice 100-200$ regs for 20-35$. Valves: 10-35$ or so. Swagelok are good. Gas tanks: look for local fire extinguisher places that...

Cannot help you with the wife. You married her, not me:FIREdevil: I can tell you if the tank looks better, and you sell a few plants etc, and make a little $, then she will like you more. Red Cherry Shrimp would be a good addition, and they can be bred and sold pretty easily. Start with 10...

Give you an idea, nice plant. Float cuttings to make new plants if you want more, or top and allow the stumps to resprout. Regards, Tom Barr

You end up with more weeds? Regards, Tom Barr

Case got dropped and throw out by the judge, at least for some(myself). I do not mind discussing it, others where not so fortunate however and may. The UK case was more about nutrients, methods etc. Did not actually go to court, just some threatening letters was enough to scare them. You...

Well, for many, it's really liberating. Now they can focus much more on the basics and what they want: gardening. Many are stuck in a rut with the old myths and dogma, it's very hard to change one's mind and be convinced otherwise. Takes a certain amount of personal humility. I honestly realize...
