some questions about my tanks

Question
I have a couple of questions about stocking and such....

okay, so i have a 10 gallon aquarium. it is running a
hydrosponge 1 with an airstone in it and a 8 inch bubble stone along the back wall. there are 3 smallish plastic plants. i have 3 zebra danios, 2 glofish, and a black tetra in the tank. should i get a new filter or will the sponge be enough, i was told it only has a turnover of about 2 gph. if this is the case i can move it to the other tank and buy a new filter.

the other tank is a 14 gallon and has 2 goldfish in it, common and a fantail. it is running a 5 to 15 over the top filter (common walmart forgot the brand name) positioned at the left and has an airstone on the right side. there are 2 med=large plastic plants in it and 2 small-medium plastic plants. is this sufficient filtration/aeration for the fish? should i move the hydrosponge in for added filtration?

also i increased bulb wattage from 10 watt compact fluorescent to 15 watt incandescent to get rid of brown algae i have been fighting, and turning the lights off after 8 to 10 hours. would the 10 watt be better than the 15 if i can limit the lighting? the 10 watt lights the tank up so much better than the 15, even though it is less wattage.

thank you in advance for your reply, i look forward to your answers.

Hi Angel: The filtration on both of your tanks is just fine.  I would not change either one... if the goldfish tank becomes messy then just gravel vacuum and do partial water changes... they are really messy fish.  Fish need light and the purpose of keeping fish is to be able to see the fish.  I would put the light bulb in that lights up the tank the best.  They make really good stuff that kills algae but is not harmful to fish or plants.  It is called Algaefix and it is by API.  I have a tank that sits in a very sunny window... so this time of year it is usually green... This year I broke down and tried the chemical way.  I used algaefix and the tank is very clear and the algae is mostly gone.  This tank has been difficult to clean because its full of about 300 half inch cichlid fry and even with the algae chemical the fry are very healthy... Hope this helps... dave
