Welcome to the wonderful addictio.....world of planted nanos
so i have a 27 watt desk lamp that i have seen other people use in nano planted tanks before. i got it at homedepot and it says that it has a "sunlight bulb" is that ok for plants it doesnt say the K (atleast that i noticed). this is the LIGHT
will this light work with out changing the bulb? or do i need to hunt for a new bulb and mostly high light stuff like glosso and low growing stuff some grasses
Unfortunately, the link you provided says that "The product you are trying to view is not currently available." However, "sunlight" could mean that it's 6500K, though I've often heard this referred to as "daylight". Perhaps "sunlight" would be 5000-5500K?
27 watts, is a decent amount of light over a 2.5g nano, though without knowing what type of bulb (i.e. straight PC or spiral?), you might not really get 27 watts due to restrike. I personally use two 13W spiral PC over my 2.5g because I don't like the "spotlight" effect of a single 27W bulb. I'm not sure whether Glosso will grow carpeted with a single 27W. I know that dekstr has grown Glosso with reasonable success using two 13W spiral PC (he has a 2.5g nano journal that you can check out here https://www.plantedtank.net/forums/pl...trs-2-5g.html)
. Grasses like Hairgrass will grow fine with two 13W bulbs. I can also tell you that Riccia will grow submerged fine with two 13W bulbs. Do keep in mind you will need to dose macros and micros if you use lots of light.
also for substrate i have seen people use unfertilized potting soil topped with sand. is this good? or would sand and a few root tabs be better? or would it be better to try and get florite in a small quantity?
Not too sure on the potting soil topped with soil, I've never used this before. I use a small amount of fluorite in my 2.5g, it's not too bad.
i would like to keep a few shrimp in the tank and maybe some tetras but not sure.
With a tank this small, I would only keep shrimp; I think Tetras would be unsuitable for a tank this size.
if it is planted heavy will i need a filter? i will do water changes once a week....or more. i know i need some water movement so ill atleast have a tiny powerhead in there but do i need a filter for somthing this small that is densly planted?
A filter is a good idea; I use a Redsea nano filter, other people use miniature canister filters (I think "Tom" was the brand). Even if you do weekly water changes, in a densely planted tank, you want to maintain some water circulation.
also i will be dosing with flourish and excel. i can put a diy CO2 system on it but will i really need it if im doing excel? also in my larger tanks i have a air bubbler run at night to off set the plants not producing any oxygen will i have to do this on this small of a tank?
The decision between DIY CO2 and Excel is up to you. I use DIY CO2 because it's not too much of a hassle on a 2.5g. As for keeping an air pump running at night, again, this is up to you. I don't keep any shrimp/fish in my 2.5g nano, so I let CO2 run all the time. The amount of CO2 is through the roof (my drop checker with 4 dkH reference solution constantly shows >30 ppm).
ok last question is it ok to take the rim off a small tank like this caz i cant seem to find many tanks that i like the look of around here. (small town)
Yes, you can take the rim off a small tank; just use a sharp razor blade and do it slowly. dekstr has also done this on his 2.5g nano.
