Dear all

The right rear of my two ft tank is planted with blyxa aubertti and it is growing so fast that I have to do a complete total cut after a month thereabout.

My question is with regard to before the trimming, will leaves of the blyxa aubertti blocked the water flow as noted from the top view that my floating plants and circulation current were be blocked by the leaves, thus, rendering only 3/4 circle water flow.

Or will water continue to flow through from the middle of the tank, thus carrying on the circulared flow?

Separately is Blyxa aubertti or cyperus helferi a taller grass?

Thks!
