Hey ringram, haven't thought about HC yet... I'm leaning more towards Glosso. But for my main 20 gallon high I'll probably look for HC since it's low light. I probably need the heater because my room is right on top of the garage, and it gets quite cold during winter season (about 17-18 degrees celcius, so like under 70 degrees fahrenheit??) when I don't turn on the portable room heater. So I'd rather keep the temp steady instead of fluctuating. My KH and GH are both at about 4 degrees, so I might add the epsom salt/baking soda (don't really want to mess around with too many parameters though).
trfjason, Oakville is kind of far for me (about 40 minute each way), maybe when I have a free day I'll visit (the gas will cost more than the glosso).
JenThePlantGeek, I think there's a bypass valve in the basement that switches the indoor plumbing to normal tap water.
BTW, update! I basically took my tallest hygrophila polysperma stem from the main tank and cut it into four pieces, then randomly jabbed them into the gravel. Also some floating plants. And finally, broke one of my spare driftwood pieces into smaller pieces, and tied java moss to one of the pieces with cotton string. This is not the final scape, it's more like having some plants in there to compete with algae. Since the last update, I found the thermometer, reduced the size of the C02 bell, and added more flourite after noticing there wasn't enough.
Can anyone identify what floating plants I have? I haven't really seen the same thing on any online profiles. The small floating ones looks like duckweed but it's not, (grows a lot slower and has red colouring). The big floating one, the guy at a LFS sold me for $1 each, said they were very rare and normally sold for $8-9 retail. He basically sold them to me for really cheap cause he said it wouldn't last in the store w/ low lighting, and needed to clear it out.
