I was looking for something that would also hold some floss, there are just SO many to choose from
so any suggestions would be very gratefully received.
I've never seen a PH that has a place for any media
Oh, I forgot I have another PH, an Aqua Clear that you can attach a "Quick Filter" to. I use it to clear cloudy water from stirring up substrate gunk but it's too fine to use all the time I think. It's more expensive, can swivel & you can adjust the flow rate & reverse it. People sometimes use them on undergravel filters, the reverse flow would the push the water down under the plates & up through the gravel instead of drawing the water down through the gravel & up the lift tubes. I haven't used UGF in many many years & never tried RUGF, too much detritus gets trapped & now I have plants that would clog the plates.
I don't know how other people might use them, I'm confused when I read that too.
Reverse Under Gravel Filter.
To aim the water flow into what is normally the up tubes of an under gravel filter. Water is spread out under the plates and flows up through the substrate. Goal: keeps debris out of the substrate and enhances the water flow so the gravel works at an enhanced rate as biological filtration.
I tried this on quite a few tanks. Debris always settled under the plates in the front corners. The PH pushes the water down at the back of the tank, generally in the corners. Most of the force of the water is gone before it goes even halfway across the tank, allowing the debris to settle through the substrate. Cleaning is pretty easy, though. Remove the intake from a gravel vac, or just use some vinyl tubing down the up tubes and suction out the debris.
PH as water moving device (w/o media): Look for Circulation Pump, something like the Hydor Koralia. A lot more water movement for the power used.
PH as filter: Some models can have some kind of media installed on the intake side. It will plug up pretty fast. I use the coarsest sponge I can find, just enough to keep bits of leaf out of the PH. Leaves can clog the intake. Even so, finer debris will get trapped and can stop the water flow.
PH with alternate installation:
See this article. You can add more complex filter media to the intake end of the PVC. To make it actually into enough to be a real filter it takes up a lot of room in the tank. I would prefer to add another external filter such as the appropriate sized Aquaclear filter (not the power head). This will add water movement and keep the tank more open for the fish.

If you really want floss media filtration, I would not use a power head. You want a slower water flow over a larger area to allow the debris to stick to the floss. The faster the water flow the more debris gets knocked off the media. If you can spread out the water flow over a larger area then the debris is more likely to stay trapped. Again, an external filter that allows you to select your own media is better than a PH for filtration.
Happy fish keeping!
A word of warning! I had a small young b. histrionica that would swim into the Maxi Jet output (against the flow) & stayed in there often. I knew that & would gently shake the PH before taking it out to clean to make sure he wasn't in there, usually his tail stuck out a bit. Then once while I was running the kitchen tapwater through the PH, out he came...& down the garbage disposal! I reached in & rescued him but between the trauma & bacteria he died a month or so later. After that I put a piece of plastic mesh over the outflow to keep that from ever happening again.
There's a similar story of small hillstream loach(es) swimming into a Koralia output & modifications done to prevent it. I "think" it's still on the LOL main site.
Can you return it?
