Hello all!
I've been fish keeping for about a year now, my tanks range from 1.5gal-10gal (10 tanks in total: Two 1.5s, four 3gal, one 5 gal, and three 10 gal) I've cycled almost all of my tanks, so all that stuff I'm familiar with.
My friends recently gave me their 30 gallon tank which had not been used for a couple years and was just sitting in a garage. It had/has some water scale build up near the top, which I've gotten most of it off, and it had some white, crusty stuff on it - which they told me was dried up algae..? What ever it was, it came off like dust, and rinsed totally off as soon as I turned on the hose.
All they asked for in return was one of my 10 gallon tanks. Easily done! lol
I'm going to be combining two of my 10 gallons into this 30 gallon. One 10gal will go to my friends, and the other will be divided so I can get rid of my 1.5gal tanks.
I have pool filter sand (Two 20lb bags from Canadian Tire) and it will house 1 male betta, 6 julii corydoras, 5 neon tetras, 5 harlequin rasboras, and a nerite snail or two. I may or may not look into adding some more neons or rasboras, or maybe some more corydoras, since aqadvisor tells me I'm only at 56% capacity.
Anyways, I took the thing to my back yard and hosed it down and scrubbed it down, with paper towel and a non-abrasive brush, and hosed it down again, and it's sitting in the sun to dry. It came with a hood as well, and a filter - but I'm likely going to replace the filter since I have no idea what brand this one is.
I have used nothing but silk plants before, so I have NO idea where to start with plants. I hope to buy a nice piece of driftwood for the 30 gallon as a bit of a centre piece and some nice, easy to care for plants to make the tank look nice and give the tetras and rasboras some place to hide if the betta gets too feisty (though he is rather good natured with tank mates).
I am on a bit of a tight budget since I have four events coming up (friend's birthday, husband's birthday, our wedding anniversary and of course Christmas), and I already have $420CND spoken for for my husband's Christmas gift... He better love it xD So money is a bit tight, so in the mean time, I cannot go ALL OUT on a planted tank. Just want it to look nice

I might still throw in some of my silk plants to help fill it up a bit more.
I also like the idea of live plants helping keep the tank a bit more balanced. When I punch everything into aqadvisor.com - it tells me that my filtration is adequate at 119% if I used a Aqua Clear 30 filter (the only good brand my local pet store carries), but if I add any more fish, it says I need more filtration. Should I just buy an Aqua Clear 50 instead, just for good measure...?
Thoughts/ideas?
