Aquarium Advice Apprentice
We are fairly new to keeping fancy guppies and have a problem with our hob filter sucking them against the intake valve and killing them in our 10-gallon tank. We'll be keeping this tank for a nursery and put the adults in the 55-gallon tank. One site says to use an underground filter with power heads so that the fry and small guppies won't get sucked up. Another says not to, that it won't keep the water in good condition. I use airstones and bubble decorations, so which type of filters do you think I should buy for our 10-gallon and 55-gallon?
