I have a question, can you explain what is happening filter wise, it's difficult to tell from the photos(thanks for them btw) exactly what goes into what?
First tank is a prefilter. starting with Jap mat then 3 courses of sponge and a filter wool pad. From this tank most of the water goes into third tank, which is full of bio-balls. but some is pumped into second tank via a 30 Watt UV filter.
second tank is empty at the minute, apart from the heaters. this tank filters into third tank also.
In the bottom tank has more filter wool, carbon filter. and also pumps water into a homemade dry filter full of jap matting, the water is pass through a sprinkler above the matting.
here some picture to help
First and second tank are 24x15x12 inches.(LxHxW)
Third is 30x18x12.
Bottom tank is 51x19x19.
Hope you understand all that.
