I tried doing 15% WCs every 2 weeks, but my sand didn't like it
I've gone back to 10% WCs every week and now my dosing is out of whack, but my sand is clean
I had a good thing going on with my dosers dammit
My Alk is up to 10.5 so I've turned off the pump and await it to drop
Now I'll have to adjust the pump timing again ....
Looks like it's time for me to dump the Seachem additive powders and get on the 2-part bandwagon
