So, I couldn't "over do it" with one or two 2ltr bottles of DIY Co2? I read all the time about timers not working or some other failure to the Co2 system and it seams to wreak havoc on the tank. I don't want to worry about that.
You can always over do it with CO2, but the output of CO2 with DIY is so low, I doubt you can do any harm. You'd have to get at least over 30ppm of CO2 to start affecting the fish.
Yes, there are concerns with using injected CO2. But try to keep them in proper perspective. Have you heard of people with tanks that have spontaneously cracked? It happens! In fact, it happened to me. And I think there's at least 2 or 3 others here who's tanks have busted. I don't mean leak. I mean in one pop, cracked from top to bottom with water gushing out everywhere.
But just because that happens doesn't mean you shouldn't get a tank. And just because some people have had CO2 disasters doesn't mean you shouldn't get injected CO2. In fact, I have killed some of my fish by accidentally overdosing the CO2. CO2 is just like everything else. You need to learn how to use it properly to avoid big problems. Just like learning to not overfeed, for example.
In my case, I was adding CO2 to my 29g tank with a pH controller. I had let the electrode sit dry for about a month which normally ruins them. But I tried it, and it seemed to work. So I cranked up the CO2.
I didn't watch it closely enough, and it overdosed. I lost a few fish and some shrimp. However, if I had been monitoring the CO2 and had not abused the equipment, then it would have never happened. Live and learn!
Skip the UVS for now. You can do fine without it. Most people don't have one.
Sit down and add up the expense of replacing the filter cartridges on your HOB for a full year. Then do the same for a canister (only the top floss needs to be replaced). I think you'll find that the canister will come close to paying for itself. Also, take a long look at just how tall a canister is and remember that the height is mostly the actual filtering media. Now compare that to the thickness of the filter cartridge on the HOB. I'm sure you can figure out a way to explain to your wife why a canister is needed. Remember that filtration is one of the most important parts of any tank, especially a planted tank.
Some sort of grass or Micro Sword (?)
Dwarf Micro Sword, Lilaeopsis brasiliensis
I haven't had good luck with this one for some reason.
Don't know what this is: (it was on sale and I need ground cover!)
I don't know this one.
This is a terrible pic, but It does show the color and leaf shape better than any of the others I took:
It's hard to be specific on this one, but I'm pretty sure it's some kind of Crypt (Cryptocoryne
). It would help to get a picture of the whole plant.
Some sort of fern?
Java Fern (Microsorum pteropus
) Make sure the rhizome is not buried in the substrate. It will rot if it is. This plant is frequently tied onto driftwood or rocks where it will eventually attach itself.
..and finally, I can't remember the name of this cat. Thought it started with a J or a P (common name).
It's a cory (Corydoras
), but I don't know which one. There are hundreds of them! Click this link to see what I mean:
Get him some buddies. Corys like to be in groups; they do not like being alone. Another 4-5 would be great.
Also, the plants in this pic is a "ludwigia" of some sort.
It's not in good shape so it's hard to say which one. But knowing it's a Ludwigia works as an ID for now.
And, yes, I looked up many of the names. Just about every latin name I had to look up. So don't feel bad if you don't get it all memorized by tomorrow. The test isn't until next week.
