The 1200lph pump for my 190L trigon is buggered & I'm going to have to use my much smaller 450lph emergency pump (was all I could afford at the time) for five weeks while I save for a new one.
Currently I do a pwc once every 8 days of 100l of the water....since this pump is going to filter less than half of the broken one, do you think I should w/c every five days instead?
My tank is understocked atm & only fed every other day to try and sort out the stubborn as shit black beard algae that's growing in it.
