Hi all;
So I was previously carbon dosing TM's ELIM-NP which was fine but even at max dose I could not get PO4 under .6. So I migrated to a diluted 40:1 lanthanum chloride solution that goes directly into the skimmer and it is holding my PO now at .23 or so. I dose in the evening.
The only reason why I am reconsidering putting carbon dosing back in action is that I have the return of some reddish/brown algae on the sand and glass that I think are diatoms (maybe cyano?) that carbon dosing seem to have it kept at bay when I was doing so.
If I dose 1/2 of the previous amount for carbon dosing - it should bring my PO4 down to about .1. Right now my NO3 is about 15-17.
Question is -is there any point to doing so. Any benefits? Any real negative consequences besides having to keep track of two different solutions.
