ok in late 1995 i purchased trickle sump filtering and was working well no problems with nitrates nitirites ect
as they sa that produce factory of them...
To avoid in side sump this sand will fill mix. bellow bio balls than sponge than big sand sponge than smaller sand
hope this will work well in slow motion flow. as this is separate piping to tube will be easier to mainten and clean
on time... lower part will be standart few cm rised to allow nice water flow across all...
