I started looking at an additional method of water movement for my 55g. I have an AC110, which is great, but it's on the left side of the tank and I'd like to get a bit more water flow on the right side. It was also 85 bucks, so while I'd love to just get another 110, I'd rather go for a cheaper but still effective route.
I seen some powerheads and koralia pumps for up to 30 bucks that would get the job done, but I also found some of the cheaper HOB
filters on amazon (like emperors and aqueons) for a similar price. I figured what the hell, if I'm going to spend 30 either way, I might as well get some extra filtration which wont hurt at all.
That brings me to my question. I'm not a fan at all of cartridges in HOB
filters, and also not familiar with emperors and aqueons (more specifically the space available in the filter box). Is it possible to just stuff a bunch of biomax or matrix into these filters and still get good flow rates/filtration?
