phosphate testing

[marie]

I'm one of those ostrich people (I keep my head buried in the sand ) If everything is going good then what I don't know won't hurt me. It's working so far and I do keep a very close eye on the animals to make sure nobody is off colour or unhappy

The only thing I've tested for in the last 6 months has been alk (If my alk drops I assume my cal is dropping too)

I've even given up testing Mg, If the coraline stops growing on the glass then I add a few cup fulls
