I put white pool sand in the 75 gal. and did order three Malaysian driftwoods which I steamed yesterday (boiled) for 2 hours. The water is pretty clear and looks ok. I also fastened the three pieces together with plastic rods so when I plant or syphon, hopefully won't knock them about. I have on order an LED with fan fixture as the set up my 75 gal came with was not adequate. Lighting (was) is a dilema as to WHAT brand, type etc. I hope to do one amazon sword, val, the moss and fern that attaches to driftwood for starter. I am still cycling the tank of course and hope to get 30 cardinal tetra first and then 6-7 ? discus. They are my dream fish. A friend told me that Cardinals carry diseases they are emmune to but discus may not be but I don't have a quarantine tank set up so hope I am not in for issues and problems down the road? I love planted tanks and did several years ago but winged it and not sure how I did that not paying attention to test kits like I am learning now.
