Redhead, Newcastle Australia. Stock: 25 Silver Perch fingerlings from Aquablue, 50 Glass Shrimp, 6 Fresh water mussels, 6 Yabbies and 4 goldfish. Started: Mid Winter Aim: To create a working ecosystem for 25 Silver Perch within a backyard pool. So Far: -pet blackmoore, gone, presumed eaten. -pet snail, shell empty, presume dead. Theory: Too long in little tank to adapt to pool environment. Oxygen: PVC pipe fitted to water jets using electrical tape, board across pool to hold out of water, water is shot out of jets when filter is turned on, shot through air and into pool making bubbles, OXYGENATION ACHIEVED! filter timed to run at early hours of morning so as not to disturb neighbourhood. Problems: -ALGAE BLOOM!!! Solutions Investigated: - ALGAECIDE-copper based, kills fish. Fish friendly algaecide, too expensive for pool quantity. -ammonia based algaecide??? -FILTRATION-each water pond seen so far has had a filtration system run at least half the day every day. I cannot do this. the pool filter is not very good. -WATER PLANTS-native water lily, frost resistant, horizontal root systems require heavy soil- not viable -floating water plants - azolla pinnata, duckweed an unidentified (as yet) floating, green, spiral shaped vine with roots, all were harvested from the redhead swamp. The fish ate ALL the floating water plants. I am getting some more. Plants of interest: Yellow Bladderwort, the unidentified floating vine, water snowflake and ludwigia peploides - https://www.australian-backyard-wildlife.com/native-water-plants.html Fish: Winter Docile, won't eat, cannot see in algae bloom AT ALL. mussels, not moving. shrimp, found around steps of pool and in filter. Yabby found once in brick (hole) with rope attached. Spring, Ostara, fish begin eating daily at sundown, a teaspoon of floating pellets. after a couple of weeks are big enough to see. purpley grey darting. still about 4cm. Goldfish try to stop the perch from eating. spread out the food. The perch are too fast. IDEA: hydroponicly growing vegetables in nets stretched across pool. any suggestions of what vegetables? any ideas on how to hold the nets taut? / keep the plants in place and not get them all eaten by the fish?... Thankyou, p.s. sorry if this is a bad read. I just started this late and needed to get everything out.
