A couple things that need to be given some thought. One is that I never want to risk killing too much good bacteria at one time to cause a spike so I do not want to move and rearrange the substrate at the same time I clean the filter as both do kill some bacteria. That leads me to not do the dirt work and then clean the filter! Rather, I like to clean the filter, give the bacteria a few days to fully recover and then do the dirt work. That leaves the filter media more ready to do the cleanup without being half full and then hit with the excess?
We all have to sort out how much cleaning /vaccing is right for us and how we do each tank. Deep vacs are right for some but I do want to point out that the folks who do dirt tanks DO NOT deep vac! Once my tank is fully grown in and has roots nearly.
everywhere, I do not tear them out to get the dirt out.
One way to deal with a temp situation like you have is to have an extra HOB handy to set on the tank for a while to get the excess out. It has the advantage of being pretty cheap and easy to clean while not going into anything that is prone to create a spike. But that also means we have to collect more of that closet full of "stuff".
But it sure is handy to set one on, let it clear the tank and then clean it and set it back in the closet, cause I'm probably going to need it again!
