Hi, if i have an old pump with no datasheet, and i dont know its suction pressure, how can i find it. I want to check how much maximum suction pressure it can provide or how much below the pump suction level, my tank can be. Thanks a lot.
Hi, I came across this term (ldvd) in an undersea aquarium report in which the level in sea were being described in terms of ldvd. Would appreciate a lot if someone could shed some light on this, I think it just means level of the points considering the sea level as 0 but I am not sure.. Thanks
