Why are none of the major power filter manufacturers producing a
hang-on-the-back power filter designed specifically for small planted
tanks?

Design Criteria:

-Power Filter/CO2 reaction chamber combined.

-Integral connection for a CO2 delivery tube. Like a venturi tube
connection...pre-impeller would be best.

-Air tight sealed design beyond the CO2 injection point. No CO2
leakage.

-Long water return path with baffles for maximum CO2 absorbtion time.
This could alternatively be a chamber with a dual use
biofiltration/CO2 bubble chopping type media.

-Below the surface water return to minimize surface turbulence.

I suppose that something along the lines of a HOT Magnum ( if it had
the connection noted above ) would be similar to what Im
thinking....but...I want something that is the size of an Aquaclear
150 for my 10-20 gallon plant tanks.

OR..... maybe something modeled on a paradigm like the Prizm or CPR
Bakpak small protein skimmers for marine tanks...without the protein
skimming but with filtration and reaction chambers.

As much discussion as there has been on effective means of creating an
efficient CO2 reactor for small tanks.....seems like an idea that one
of the manufacturers would have explored.

If I was in any way skilled with acrylic....I'd try my hand at
building a prototype.

Probably not enough demand. :-)

Yea, I was going to say that too.

Bob,

What is it about the HOT Magnum that meets your criteria?

Thanks.

Heavy emphasis on the "if" part of my original statement. IF it had a
connection point for CO2.

as to how I envisioned that it might fit the criteria....

-it hangs on the tank like a power filter...for the applications I
have in mind I dont have space for an outboard canister.

-if CO2 could be introduced pre-impeller the entire internal part of
the filter is more or less as a reaction chamber. using the internal
canister instead of the micron cartridge you could put some kind of
bubble chopping bio media into the canister.

-it's leak proof such that once the CO2 is introduced it isn't free to
escape like a normal power filter

-the water return can be directed below the surface as opposed to
normal power filters which simply spill over the edge therefore less
CO2 loss.

I'm pondering using one of these for a new 30 gal tank on an unused
stretch of kitchen counter where only a "hang on" type of filter will
work...and bubbling the CO2 into the intake.

I am and have built them but they would run 100$ each and would take a
great deal of labor to produce.
You could speed up production etc but would you sell enough to warrant
that?

It's business, you need to sell a large number of filters to make that
profitable.

A simple add on tube with it's own pump so that the aquarist does not
need a solenoid to have semi or automatic control is a more flexible
better idea. The added flow rate with the extra pump increases mixing
of CO2 when the plants need it.

Filters get clogged and slow down, get hair and what not in them. This
will effect the CO2 also.
By having a separate CO2 system, you avoid this issue.

If you have a fluval or a HOT etc, you can add a CO2 reacting tube
after the filter and some have done it before. Check valves and
solenoids are needed for semi or automatic control, but if you add CO2
24/7 , it's less of an issue.

If you have a hang on the back wet/dry filter , you can place the CO2
reactor in the sump or in regular wet/dry sets up as well.

That's what I do.
