I'll chime in as well and state the few rules/ideas I had when I set up my FR: I made sure to have a simple water changing procedure. All tanks are drilled for outlet and I just add water through a hose connected to the tap or a pump in the RO/Peat-barrel. I didn't install a totally automatic system as I realised that the water in the various tanks would/could be quite different from each other. If all your tanks will be using the same water I think this is a good idea. I built all my racks/stands in wood. Easy to handle, cheap and easy to repair or modify. I haven't protected it with epoxy coating but I have elevated all wood stands from the floor using concrete stones. I cover all tanks to keep humidity down. Mine is typically at 45-60% RH at 25 deg C (77F) and that is not harmful to either the stands or the electrical appliances. I have no problems with electrical stuff or metal tools in that humidity. Working space. Cleaning space - a big sink to slob with cleaning filters, gravel and smaller tanks perhaps. Recreational space ? Just make sure you make working in the FR easy. If it's difficult or hard work to do it's less likely to be done (or done often...) /Fredrik ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
