I loved the stuff that came with my tank but I thought it still looked a bit bare.
After looking at all the lovely pics in tank of the month I decided i like the heavy planted and natural look.
So today I got 4 new plastic plants (Large red ludwegia, small Moneywort, small anacharis and a medium sised Hornwort) and I grabbed 3 red rocks (they were called red rocks but they look a tanish/red color)
I cleaned them, did the vinigar test on the rocks, then put them in
It looks so much better.
I placed 2 of the rocks one tall one short together to make a triange with a plant in the middle and the other rock near one that came with the tank.
I am happy with it except for one corner of the tank, its a little dark so..... you guessed it! Im going to get another large green plant to brighten that corner up
I will post pics of before and after when I can
Sounds like it's looking pretty good.Can't wait for you to post pics & share with us!
