does anyone have any tips to increase suction?
yes, increase your water pressure.
The system relies on the strength of the water coming out of your tap. if you haven't got very strong flow coming out of the tap, it won't have a lot of suction at the other end. I bought one about four or five years ago and had exactly the same problem as you. It would lift a certain amount of waste, but leave behind big solid pieces. The water coming out of my tap is fast, but not fast enough or strong enough to make the Python work to its fullest performance.
I feel that the manufacturers should make it clear to people buying their products that if they haven't got strong water pressure, it won't work properly. I feel that they are misleading people by not putting a big notice on the front of the packaging telling people this information.
I also think that Python is bad for the environment. After all, we should make efforts to conserve water wherever we can. The Python wastes water terribly as you have to have the tap running to remove water from the tank, And then again to put it back in.
In my opinion, the Python is a complete waste of money. You also have to bear in mind that all your waist goes into your sink. Would you take a dump in your sink? Of course you wouldn't, so why would you want all fish crap going into it? so not only is it bad for the environment, it's all so terribly unhygienic. Save yourself the money and get a length of hose and a normal gravel back, does exactly the same job, and even better
