Overflows.... whats the trick?
Ok so i have 2 powerheads 1x all pond sullotions 2300 and 1x jecod rw8 (cant use this on the lowest of settings may see if i can trade for the rw4 with someone)
I cant seem to find a good placement to get crud up to the surface and down the overflows?
any tips? Not much point in having a sump if its not being fed : )
