Good start!
In addition to more plants, I'd scoot the one sword a bit away from the corner (they do get quite big) - and I'd switch the sm. Cichlid stone and driftwood positions, the DW is a bit too centered.
Any chance you can find another, larger DW piece?
Also - I'd position the heater horizontally along the bottom (an inch or two off the substrate) - no need to see it all the time. The film on the water surface should dissipate on its own if circulation is adequate, otherwise blot it off w/ a (strong - not generic) paper towel or coffee filter.
Actually the rocks (cichlid stones), and Amazon sword are coming out on Tuesday when the plants get here. The driftwood will be moved them. I dont have an exact plan for the location of the driftwood, but there is a firm plant layout, and I will squeeze it in if I can. The way the tank looks now has always been just a temporaily thing, believe me, I know this layout stinks, :hitting:.
The deal with heaters is this, both are techincally the same exact model, but one has a different power cord and says "submersible", and the other says it can only be submersed up to xxxx line. Since I didnt want to risk ignoring the directions, I keep both of the tops (where the temp dial is), out of the water according to the marking on the heaters. In my kids tank, I also prefer a horizontal approach to hide them heaters low in the tank.
Also, since buying these heaters, I have adjusted them to reality. At first, these things were reading like -5 degrees F compared to the actual water temp. The eheim heaters do make it real easy to re-calibrate them, or whatever it's called.
I do like your idea about coffee filters, I am going to try that with unbleached filters. :thumbsup:
Thanks for reading, keep checking back.
