Ya, I don't really want to dose so I will keep an eye on how much things are dropping.Yeah just watch it close test at least weekly if your dosing it. Once phosphate get low enough it will start to rise.
How are you removing phosphates algae scrubber, cheato, carbon dosing, GFO?
think about this so when you start a new tank it takes half a year or more for rocks and sand to stop absorbing phosphates so all appears fine then one day boom phosphates rise dramatically and then you get hair algae on rocks and it keeps coming back as phosphate leaches back out of the rocks as you remove phosphates from water (by pulling it out or other control measures)
need to use one of the mentioned methods above consistently to keep algae growing slow enough for CUC to control but not so low or controlled corals don’t have enough to grow
I have caulerpa in the refugium that is currently being out competed by the gha. I will probably give chaeto a try.
That's a good point on the removal of phosphates. I am hoping I can eventually control it with chaeto in the refugium, but we will see. If not I might try the algae scrubber.
I noticed last night, after lights off that I have tons of small snails all over the glass, but not a single snail on the rocks. Is that odd or is it just me?
