Is it still possible to order one thru hastings? Will pretty much any plastics company be able to build one if given the design? I may need to modify the lengths a bit for various other tanks(156g and 65g). A few other questions about it. Is there anything you found out over time that you wanna modify to your original design? minor tweaks etc?
Also I may not be able to get enough flow from just my overflows. Would a separate pump running just the scrubber be the best way of doing it?
