Hey, I want ultra hot thai food!
I don't know if you can blame the oceanic salt for cyano and hair algae, sometimes I think they are just some of the flora that pass through a cycling system (and you can have a cycle repeat if the system is messed with in some major way like med use). I think some foods promote algae, the juice from frozen or uneaten flake if you use that. Debris in the tank helps too.
I have seen other problems with cyano, like it popped up after a year in a system and then went away when phosphate was cut by doing a few large water changes, carbon, cutting the feeding and using R/O water. Guess I did siphon out the largest bits.
I have taken rocks from other peoples' cycled tanks and put them in mine, those rocks suddenly sprout hair algae like crazy when neither system had it previously. They came out of low flow tanks and there was a lot of sediment on the rock for the algae to eat which I should have blown off with a powerhead but instead placed in a low flow area, and algae traps more sediment which they utilize... Using a lot of flow to keep the debris moving toward the filter will help starve both cyano and hair algae. Allegedly. That's what the experts say and it has been my experience, but then I have had both just disappear in very low flow tanks for no reason at all with no effort on my part.
What I wonder is if the Ca is way out of whack then what is precipitating out and what is it bonding to on the way, if that could form a sediment to feed the algae then you could explain high Ca causing algae. Sounds like a question for another forum. Seems like whenever one thing is high another is low and then you have problems.
Praise the coffee and pass the thai food
