No we don't use it - should we be? We did get a bunch of average plants one time and too cheap to throw them away without giving thema go.
The tank is 165l and water change every weekend. We have a few too many fish but are getting a second tank on the weekend so will split them up. 5 gouramis, 5 platys, 5 rummy noses, 6 neons, 3 glass cats, 6 Rasboras, 2 bristlenoses.
