I have a chinese make (Tianrun brand) HOB rated for 200lph running on my 5G planted that seems to have reached its half-life.
I say this because the flow rate has drastically reduced on this filter and I am starting to doubt if it even does 100lph now.
Has anybody tried any DIY ways to improve a HOB's performance? And by performance, I mean the flow rate.
I googled this topic only to find hobbyists either replace the impeller with a bigger (more no. of blades) one or add another pump at the intake. Both of these seem to be overkill for my case though.
P.S: I do have a backup HOB (that I got for another project) but I dont want to use it unless absolutely necessary.
