20g Long Planted Tank Filter Questions
Greetings fellow planted tank enthusiasts!
Iíve decided recently to start up a 20g long, male-only, fancy guppy tank, and could use some advice based upon the situation Iím in. Iíve (hopefully) attached some pictures for you to view.
In regards to the tank itself, I planned to do a nicely planted aquascape with the following:
-Potting soil substrate capped with Black Diamond/Black Beauty Blasting Sand
-Planned plants are: Anubias for foreground, Java fern and Amazon sword for Verticality, and Frogbit for floaters (Plant suggestions are welcome, but if possible Iíd prefer those that are purely green so the Guppies will be the main focal point with their color.)
-I may consider setting up a CO2 injection, but that would be at a later point in time. In the meantime, I would be dosing with Excel. (Speaking of which, are there any carpet plants that could do well with just doses of CO2?)
-The tank itself has a glass canopy, to prevent jumpers and to prevent water residue on the light source.
Now that thatís out of the way, my dilemma comes in the form of the filter. Currently for my 10g and 37g tanks, I have Aquaclear filters, usually twice the size of the tank. However, the placement of the tank causes the tank to be viewed from both the front and the back, with the back side of the tank facing the front entrance. Looking at my options, I have the choice of internal sponge filters, or internal canister filters, although Iím leaning toward the sponge filter option.
Considering my lack of experience with either, would 1-2 sponge filters suffice for the bioload? Would not having the carbon affect the clarity of the water?
