Just an update if anyone cares, but I have ordered a new full CO2 setup, and also ordered a 10" FugeRay for the tank as well.
Again I need heating suggestions, also debating if I want to stick with the cheap glass diffuser or not. Haven't done much reading, nor do I have the time so i value your suggestions.
Also RcScRs - I intend to keep just hairgrass for the time being just for ease and uniform maintenance. Keeps it a lot simpler. Original plan was to have glosso up front, but decided just to have one species of plant in there to keep things manageable.
