these are a few pics of my indoor combined tropical pond and tank system. it is based around my custom built octagonal aquarium of around 700l
i designed this tank myself. it is made of non magnetic marine stainless steel with a solid steel base with 10mm plate glass panes. the base has two inlets a flow which is connected to the pump in the pond and the return overflow which feeds the veg filter. the tank is lit by a 250w mh lamp and houses a small shoal of apollo sharks, a large silver shark, a plec and a large synodontis and up untill recently a male green terror(sadly died at the age of 10) and a SA antenna cat of which im not sure of the name(will post pic for id elsewhere on MFK)
the veg filter is based on a hydroponic tank consisting of a perforated planter which sits on a reservoir this has a 2" pipe connected which takes the flow to the top of the waterfall
the veg filter is filled with hydroton clay pellets and planted with peace lillys.
at the bottom of the waterfall is the pond, a second hand ebay bargin of approx 800l this is well planted with a big amazon sword, anubia,vallis and a few crypto's as well as java fern and moss.apart from afor mentioned catfish stock is light with corys,ancistrus, various characins and barbs. lighting is natural sunlight suplimented with 4 t8 48" tubes(6400k). heating is 1x 200w summer, 400w winter pH is stable at 7.8 temp 29c EC 0.4
