So…my protein skimmer impeller is not working. I can do a couple extra water changes and let the live rock/sand handle it for now, but this issue will need to be addressed quickly. Can I simply buy a new impeller, or do I need to get an entirely new skimmer?
Second question is that, assuming my bank isn't broken by question A that I am looking to add a sump underneath my 40g. I have two old tanks unused, one 10g and one 29g high. Haven't decided which I'll use, as the debate is water volume vs space to work with, but either way what gph should I look for in the return pump? And should I look at gph vs the main tank or the entire system?
