Aquaclear model 70 are great.
Seachem/Tidal filter are great too.
AC series:
I like to run two AC70 filters on some projects as well as other filters.
One Aquaclear 70 intake free to grab chunks, the second Aquaclear filter gets a pre-filter sponge on the intake to protect the Aquaclear's sponge in the media box.
Aquaclear filters can be fitted with a 3/4-inch PVC elbow or some of the black ABS plastic junk drawer elbow from pre-drilled tank kits that were supposed to fit return lines and so on.
One AC filter stays very clean and needs service every so often whereas the 2nd filter (no prefilter intake sponge) grabs more chunks and needs service sooner.
A combination of filters is best.
Another trick for too fast of flow is to use a airstone sponge/bubbler in front of the flow of an Aquaclears current.
It knocks the flow (spreads it) from being too fast.
Filters (in my opinion) should usually be run on full power for good filtration and the current spread out using creative ways to combat the fast rush of water.
- a baby gate of craft store plastic mesh can be cut to fit an Aquaclear to spread out the output just as it runs out of the ramp too.
- twisty ties can hold it in place or tuck it in.
Seachem/Tidal series:
I love Tidal filters too.
They have there place in helping.
- remember the Tidal filter box has a taper to it though.
For example, you can easily use a blue Tidal 75 foam with minor cuts to fit or stack foam in a Tidal model 55 box snugly.
- also, the Tidal filter's blue foam from a Tidal model 110 can fit (stacked foam method) the model 75 box with the same principle.
Some stores actually have smaller porosity (ppi) black colored laser cut foam for the Tidal filters that is oversized and fits the box as it tapers.
Tidal filters are nice too.
Lots of photos:
A timer (below) from Amazon can also aid in bubblers, hang on filters and more for turning things off for a few minutes or hours while you feed your picky fish.
I especially use the OFF Timer for air bubbling as I lift/fold the tank's glass lid as bubblers spatter and pop.
- very easy timer, $12-14 bucks.
