I agree, I likely would have never gotten into the planted tank hobby as much without CO2. I've had plants for decades before, but never at a high dense level really before about the late 1980's. But every tank had plants. We have a nice little "seedy" fish shop here that is much like the...

I have a large 350 gallon or about 1300 liter plant tank with many fish I'll post sometime in about 1-2 weeks, it was not tended or taken care of for awhile and they have started caring for it better. The care taker was fired from the job so they have a new person to add the fish food and dose...

Yes, we need jobs! To pay for the hobby! Haha, that's E parvula, dwarf hairgrass. Note, you can use a large toothed comb to keep it clean and also "mow it" just lie regular lawn grass. With non CO2 methods, you can have more time for work and less for pruning. :idea: But many like...

Hallo Kora, Yes, electric, gasoline, lighting, all cheap here. We complain still though:) Many of us have long tried to promote lower lighting. Such aquariums do better and have more resiliency. They are much easier for new people and experts alike. But the USA is a place that many...

The Rubicon is awesome! Great for 4 wheel driving and Moto cross! Regards, Tom Barr

Nien, est Venronica anagularis aquatica Looks like Ammannia though! Regards, Tom Barr

Learning patience is about the best thing that you can do in this hobby:) Fast or slow growth. I used everything from 1.5 w/gal to 5.5 w/gal on the hard water tanks. You need to watch CO2 more(not a bad idea anyway) and add more traces, something with DTPA rather than EDTA or gluconate...

Many of the plants are considered "weeds". Many of these are in national parks or state parks where it's illegal to collect. But outside the parks, in irrigation canals and ditches, many of these plants grow. A snip of a piece for vegetative propagation is likely okay or collecting of seeds...

Hallo Maik, this is Utricularia vulgaris, it's about 3-4 cm in diameter, the weed you have is Utricularia gibbla, far worst than algae as it's a plant and very tough to get rid of. The plant I showed is a nice Utricularia, much like U. grammifiola or U. stellaris. To remove the U gibba...

This is the world's largest living tree/thing. At Sequoia national park: The redwoods are the tallest, about 110 meters. Mt Lassens volcano: See the Crow's foot growing in the stream? Hard to beat this place. Giant Alpine Pondweed: Burney Falls is awesome...

Tidepools here, I keep marine tanks as well. A prime evil redwood stream Callitriches macrophylla in Yosemite national park, Spring. Willow moss red due to low Nitrogen in the same stream. Weird! Callichtriche and crow's foot at Folsom lake not far from where I...

Here's a photo journal of the locations and habitats in California USA, I took at these pictures the last 1-2 years. Can you guess what plant this is growing in the Santa Ynez river in Santa Barbara? Veronica anagularis-aquatica! It's green in the aquarium but in very hard water and...

Well, some folks get tired of fast growth, so they have that option, if you have a nano tank, then it really makes sense: here's an example of a Killifish tank that I've had for about 2 years and never did a water change: No CO2, what you see is what you get in this pic: If I added...

Well do we really need to add CO2 gas to do this though? :idea: Haha, the answer is no. So what does adding CO2 do? Well, it amplifies and stabilizes (hopefully) plant growth, but about 10-20X! It only amplifies plant growth about 10-30% in terrestrial plants. Aquatic plants are generally much...

Yea, it garbled some German very bad. :roll: I am good with Italian and Spanish because I know the language better, but German often should come out better than that! If I keep the language simple and use certain words/nouns, then the engines work MUCH better. But then I have to edit a lot and...

Hallo Sabine, I have hello Tom, in my " Hills of Irishman's land " a rather good growth of Hemianthus Callitrichoides Cuba and a very good growth of Glossostigma elatinoides, Limnophila aromatica and a. My KH of the tap water sways between 6 and 12 and these variations seem to put out to the...

Yes, good translation! Ingrid's got muddled. Yes, we had wide ranges of nutrients in our tap water here in the USA, but generally low NO3. I've been personally interested in various Na and Cl levels as well as KH and GH levels. So we have a long list of comparisons from local areas and...

I have a nice example from our laboratory where the same plant and genetic stock is very similar without any water column fertilization. the system has a flow through DI water system so that all the nutrients must come from the sediment exclusively. This allows me to compare nutrient sources...

I raise this plant in large amounts at 2-3ppm of PO4. I know because I add no less than 3ppm per week of KH2PO4. This cannot be true, it does not imply why they get stunting, only what it cannot possibly be. If you assume that this hypothesis is "true", then adding 2-3ppm of PO4 should induce...
