A: Green water is caused by algae. Sunlight is one of the main causes of algae, along with over-feeding your fish.

A: Many treatments are available ranging from chemicals to ultraviolet clarifiers. Many of the chemicals have to be added on a regular basis. The ultraviolet clarifiers have to be run in conjunction with a pond pump - ideally for 24 hours a day. They range in size according to the gallonage of your pond and also the amount of water you will be passing through it with your pump. It is very important you get the correct unit - which range from 4 watts to 10 watts - if the correct unit is purchased, your green water problems are over!

 

A: Because most ponds are an irregular shape it's difficult to calculate exactly how much water they hold. However, if you measure in ‘feet’ the average Length, Width, and Depth, you can use the following formula as a rough guide:

 

LENGTH X WIDTH X DEPTH X 6.23 = GALLONS

 

A: There is no set amount as it depends on the size and type of fish you want to keep. You can however get a rough idea if you follow our tables below:

(The following is only a guide)

 

1” of fish to every 1” of tank length

 

1” of fish to every 2” of tank length

 

 

A: It is better for the well being of the fish NOT to put too many in too soon. The best thing to do is to use a bacterial enzyme with the initial setting up of your feature, this will help to boost the filter system and start the Nitrifying bacterial process needed in all aquariums and pools to break down the fishes waste products. Then leave it running for 7 days before adding any livestock, this should be done slowly as the filter needs time to adapt to the quantities of fish being added .Certain fish will withstand the changing water quality of a new system better than others, ask at your local store for advice on which fish would be best suited to your feature. It is always a good idea to have your water tested for Ammonia, Nitrite and PH about 2 weeks after having put your first lot of fish in. This will tell you if it is OK to carry on with stocking your feature or to wait until the nitrifying bacteria has had a chance to colonize the filter more efficiently.

 

A: If the water looks cloudy it could be that your gravel has not been washed properly. This should settle within a couple of days, if not, you will need to change some of your water. It could also be that your filter has not matured enough and the waste products from your fish have built up causing a possible Ammonia reading, small water changes on a regular basis, adding a bacterial enzyme and cutting down the feeding of your fish should help to reduce this problem, but do not expect it to disappear overnight it will take time but you need to be patient. Do not at any time wash your filter foams out in tap water as you will wash away any bacteria which has already started to colonize your filter, these should only be gently washed in water from your aquarium.
