I have a proclear overflow connected to the pre filter which connects to one of those pool/ vacum hoses with connects to the bulkhead on the drip tray. I am seeing a little water coming from (or leaking) one the lower end of the hose. All fittings are not leaking. Could it be that the vacum hose itself is leaking or ; 20,0000 times a day i empty the skimmer and water drips everywhere when i remove the collection cup on the hot bak pak.. could tat be it? Im parinoid with OCD so im reallly worried for the smallest things. Especcialy concerning my reef.
