Backyard Aquaponics
A place to discuss aquaponics

could the high PH of the live rock contribute to the high PH needed to grow spurlina? once the live rock's PH is lowered they can be replaced with new ones and the old ones can be put into a seperate system with say "prawns" to grow algae on them. it all sounds pretty simple no matter how complex it is, would this method work to grow both spurlina and the liverock algae?

Hi VB
Pavlova lutheri, Isochrysis growing rotifes

Pav and Iso eh? sounds too familiar- I work at an oyster hatchery in S.A. and we grow around 10,000 litres per day of the stuff.

I've been interested in saltwater aquaponics for a while esp seaweeds (on a commercial scale). There's some interesting stuff going on in Israel- incorporating abalone, fish and red seaweeds.

You are spot on adam. I have been getting sydney rocks Osyters they are the next thing to go in to the AP system Just need to get the algae right. Tailor made aquaponics in NSW have been experimenting with then in there new salt water system.

Adult oysters eat a huge amount of algae, but very interested to see how it goes.
