We recommend you do a 10% water change once per week during the summer months.
Add dechlorinator to pond and then top up with cold tap water (on a spray to water surface, not below water level).
Pumps and filters should run constant (do not turn off overnight)
A filter grows a beneficial bacteria that converts harmful fish waste into less harmful nitrate, this takes approx 8 – 12 weeks and water quality should be monitored closely during this time. Test for ph, ammonia and nitrite.
During the summer months the fish can be fed up to 2-3 times per day, water quality allowing but only feed a small amount. All food should be eaten within 3-5 mins, if not leave for up to 20 mins then remove excess from your pond and throw away.
Clean filter sponges only when needed (flow rate usually slows down indicating they are clogged, or water bypasses sponges to overflow facility in filter box). Use a bucket of pond water, give the dirty sponges a squeeze to remove heavy dirt, if water in bucket gets too dirty throw away and repeat.
NEVER USE TAP OR RAIN WATER TO MAINTAIN SPONGES AS THIS WILL KILL THE BENEFICIAL BACTERIA CONVERTING YOUR FISH WASTE!
Replace uv bulbs every spring to ensure clear water throughout the summer months. UV bulbs get weaker over time and lose effectiveness after 6 months of use (although they will still light)
