You should really get a algae eater. Some of the alge killers are harmful to the fish.
it really depends on what type of algae. if its green water algae then use and algicide which you can purchase from aquariums. if it's filament algae then get some snail or algae eating fish. the quickest solution is to scrap the algae off yourself.
I don't know that question but depending if you have hard water or not you can put
a couple algae eaters in there from the pet store
Most likely not, It is made up of bicarbonate which the algae can use as a carbon source. So adding baking soda will most likely increase algal growth.
snails
you kill the algae
Goldfish will feed on the algae and minute organisms found around the weeds.
Algae in a goldfish pond is quite common with an increase in sun (light) and temperature. To try and keep algae to a minimum you will want to look at ways to provide the pond with shade, and regularly change out some of the water for fresh water during the warmer months.
Most likely not. If there are goldfish, then there are definetely going to be predators. Goldfish are small, and one predator could eat about 5 goldfish. It's very unlikely, but possible.
Algae covered the top of the pond. The pond was full of algae.
Some goldfish I guess. It depends on if it is wild or not.
When the crayfish ages, it has a chance of chopping your goldfish to pieces, and possibly eat it.
Yes, it is because without any algae some living animals in the pond would die. Algae can be food for some creatures in the pond. If your pond is just for admiring and not for living creatures, no, it isn't because the algae will take over the pond and no living creature is in it to eat the algae.
pond
yes
The goldfish will eat the mosquito's larvae before they can leave the pond and fly.
