Pond Vacuums

What vacs do u recommend for a 24/7 indoor cat.. are all truly needed? never exposed to outdoor cats. ty

I have two gold fish that live in a 55 gal tank. The water is clear, but brown starts to accumulate on the inside of the glass, and on the ornaments in the tank. I have been using a few different water treatments, the water is clear. I use a sponge tank scrapper to get it off of the glass, but the ornaments are all covered with brown. Is there a fish or something else that would clean that stuff up?

How to get remove all planaria worms (crawling our aquarium glass in a tiny size )from freshwater tank ?

Is the 5way vac for puppies 8 weeks the same vac used for annual in adults

Is this tank big enough/small enough to hold goldfish fry (these fish will not be in it we are just cleaning up there other tank)

Help! The submersible pump on my 3.7 gallon is making loud motor sounds and spitting out small bubbles that by morning cover the whole top of the tank. I’m scared for my fishes life what should I do?

How do you attach a skimmer to a tank filter?

My fish tank is getting brown on the decorations and gravel I tried cleaning it a couple days ago but came right back

My fish lived outside during the summer eating alge out of our pond. Now it's inside for the winter but it has developed a white growth on its forehead

My 55 gallon fish tank has hard water how do i clean it out that won't harm fish?

when i was little my grandfather had a koi "patio pond" in a metal stock trough. I was wondering if it would be reasonable to do the same in a rubber one?what considerations would you consider?

I have a 26 gallon tank that is overrun with cone snails. We suck them out with every water change, but it's a losing battle. I've tried clown loaches to no avail. I think the snails are responsible for the green look to my water. Is that possible, and now can I remove them w/o tearing the entire tank down?
