Question about Intex Easy Set

Yes, a pump is included (and sufficient if you care for the water properly, but not sufficient to filter out algae infestation etc. - only filter cartridge, no sand filter). PH reducer and chlorine are certainly not wrong, but it seems to me almost more important to have an algae agent, otherwise you will have algae in no time (a few days, at most weeks). Since it takes a while to fill it, leads to cold water again and in our case costs almost 20 francs, it's worth it. There are also more powerful sand filters/pumps from Intex, but they need more electricity, are louder and have somewhat larger connections than this pool.

Hello, does anyone here know which sand filter pump fits this pool (connections etc.)? The pool is in constant use at our house and the pump that comes with it can't really cope. I have seen that there are sand filter pumps for the larger pools, but these have (my interpretation) larger hose connections/diameters.
