    plant advice

    Putting the tank in front of a window is just begging for an algae bloom. I wouldn't try it. A 4ft T8 shop light is pretty good bang for your buck. The Marineland Double Bright fixture would work for plants.

    Playground sand?

    Sure. I have play sand in one of my tanks. Just be sure to wash it really well. It's very dusty out of the bag.

    help with ammonia - confused

    First, make sure you're holding the tube on the white space of the card and look at it under good light. Bad lighting can really screw up your reading. Second, there are ways to calibrate your test kits. It's not very complicated, but you need exact measurements. Dig around online and you'll...

    Algae Issue.

    I've noticed that I get less algae on my glass top since I reduced the amount of micro ferts I add. It stopped the weekly green water outbreak too.

    Jungle val in low wpg?

    +1 They spread like mad, but they don't grow very tall very quickly. I've got some in a 29g with a couple CFLs and they're just reaching to the top now after probably a year in the tank.

    Tempered glass or not

    Tempered glass is stronger than untempered glass, but you can't drill it. The only tempered glass I've seen in an aquarium is the bottom pane, and not every aquarium has this. I'd go with the untempered glass.

    Moving an Aquarium

    I've moved several tanks by draining most of the water and leaving everything else. Be sure to have some muscle available. I can handle moving a 20H by myself in this manner, but that's about my limit.

    Shrimp w/ Angelfish?

    Angels will most likely eat any shrimp you put in the tank. Mollies may do the same.

    Info about using a Python

    +1 for meegosh. I used to check the tap temp with an instant-read meat themometer, but now I just go by touch.

    Sand blasting sand

    I've got Black Blast coal slag blasting compound in my 40B and a 5g. $8 for 50lb was too good to pass up.

    research project?

    I'll put the fact that the tank is too small for the fish aside for the moment. I think the tank will be too small for you to get any kind of good result for your experiment. Let's say you've got a 14" bass in a 40B. At most the bait will be two feet away from the fish. Bump the tank up to a...

    almost finished

    There are some high pressure pumps available. You'll pay for the power though.

    Lighting, LED or flourescent?

    Which fixture? The Single Bright isn't worth much. The Double Bright has given people good results.

    Lighting, LED or flourescent?

    Fluorescent lighting is more than sufficient to grow plants if you have enough of it. T5HO does wonders for plants, but you burn more energy than comparable LEDs. Fluorescent lights are cheaper than LEDs though.

    Lighting, LED or flourescent?

    If you get the right LEDs, your plants will benefit. I'm able to grow high-light plants in a 20H under 30W of good LEDs. The moon lights are designed to be left on all night, but it's really up to you.

    Duckweed?

    I get duckweed in my tanks during the summer. It's a pain in the neck to keep scooping it out.

    Heater advice needed

    I have a Hydor Theo in my 20L. I can't remember if it's 100W or 150W, but it stretches from top to bottom in the tank.

    Is this lighting ok to grow plants?

    Unfortunately not. Fluorescent bulbs are generally one wattage per length. The only exception I know is you can get 48" T8 bulbs in 32W and 40W varieties. How deep is your tank? If it's a fairly shallow tank, you might be able to grow a few plants directly under the lighting. Otherwise, you...

    To the DIY CO2 Experts....

    Try the air stone. Before I went to a pressurized system, I used a piece of the free chopsticks from the local Chinese restaurant. If it plugged, I'd just chop off a new piece.

    outdoor loaches

    Supposedly there are places here in northern Illinois where dojo loaches are considered an invasive threat because some idiot dumped them and they've thrived in the local waterways. If they can survive the winters here, they'll have no problem outside in the summer.

    To the DIY CO2 Experts....

    Using the filter as a diffuser will work, but the agitation of a sponge filter will off-gas a lot of your CO2. You'll still need an air pump. If you've got enough CO2 pumping into the tank that you can run a sponge filter, you'll poison the fish. Airstones can also be used, but they put out...

    need help creating a "carpet"

    Small tanks don't follow the Wpg guidelines very well. Like aqua_chem said, CO2 is important. It's pretty much impossible to get a steady CO2 supply with a DIY setup. Excel is a mediocre substitute for a pressurized system.
