Apung Filtration Set Up For Tvr, Will this affect swimming style for my TVR? Options

[apungcool]

Dear RG members,

Currently i use filter like shown below in my TVR tank





Filter consist of three levels where in each box in every level I put bioballs. The size of my tank is 2 M x 1 M x 0.5 M. From the top level, water flow down to the next level until reach and poured to the pond. I made plenty of little holes in the bottom of each box in order to divide the flow cause many say that large water flow will impact to swimming style of TVR. I put it on the top of my house's roof so it get plenty of sunlight. Sometime the water turn to clear water and sometimes to green water. My question is, does my setup still give negative impact to my TVR's swimming style? Any comment is welcome for the improvement of the set up

Thx
