- Copper Testing Simplified! Using Hanna Instruments High Range Copper Checker HI702, May 26, 2018 at 1:12 PM
I'm trying to grow chaeto in a chaeto reactor and hair algae in a CW100 algae scrubber. However, I get low to 0 phosphate readouts using a Hanna Checker:
The phosphates presumably came in due to a die-off. Green is phosphate and black is ammonia. As can be seen from the graph, both are 0 until a small spike with ammonia around the 26th; however, there's a cataclysm on the 2nd, when ammonia is no longer 0.
Traditionally, I understood that algae needed both to grow. However, it's been cited in scientific literature by Randy Holmes-Farley that sometimes algae in limited phosphate conditions can survive on just the other nutrient. Do these apply?
How do you know when it's time to dose phosphate, and how do you know when there's actually phosphate in the aquarium being consumed at the same rate it's being produced?
Do I need to dose phosphate in my case?
#Mods if needed, perhaps this is a question pertaining to water chemistry instead.
This is posted in the wrong area. Maybe one of the #mods can assist in moving it. You have this in a sponsor forum. You'll get more assistance.
With the equipment you have you should be able to do a nice frag tank.
I'm using a 10 gallon jbj for one currently. Jay added a few snails and a couple hermits to help with a little algea. Been setup just over a month and doing great. Do a gallon water change per week.
