Tank maintenance is the key to all this and good cleaning regime is what is required here, the back is accessible as its not totally against the back pane as that is were the heater and pipeworks are hiding. Its also my intention on giving the tank a "Hurricane Effect" from time to time which in effect is to force a strong surge of water totally around the aquarium to flush any detrius from out of the holes and crannies. Apparently it's a good thing to do about twice a year. I've only got a little bit done but will post a pic on my thread later on today. It looks good (bighead) and I know I'll probably get slated for it, but I'll persist with the venture and see it to fruition good or bad, time will tell. I am much too long in the tooth now to get excited about doing things quickly. Good maintenance is essential yes but other things need planning and patience is a virtue. I like the planning phase and the final setting up is the end product. I am always thinking even to the point of family members asking questions and I am un aware of what they are saying cause I'm deep in thought on a particular problem. Dam Fishkeeping, my family's right "I am going insane"
