im looking into either a 100 or 150 gallon stock tub tank for trumpet and want to diy a filter for it. it will probably have space at the top to prevent him from having another escape.
i have what i want to do basically worked out; water flows through a pump into a plastic tub (smaller stock tank? just a regular rubbermaid plastic storage tub?). it would go through the lid of that and into a bucket full of mechanical filter media, and then would drain from the bottom of that bucket into the bottom of the tub and through a basket full of bio media (probably those scrubby sponge things everyone uses, cant remember the name) and maybe some bio balls, which would go through a pipe and back into the tank
so how big of a filter tub would i need? does that matter? how many gph should the pump be? the pumps im looking at currently range from 550 gph to 656 gph; is that too much? should i do more? is there a certain brand that's recommended, or certain brands i should avoid?
while im at it, what's the best way to do a basking dock in these kinds of tanks (and the best way to rig up a light, because i doubt ill be able to hang it)? and do stock tanks need a lid?
