If you guys are ever feeling frisky, give the Tropic Marin Bio-Actif salt mix a try. It will blow your mind and I'm not exaggerating. If I could afford it, I'd always use it.
You have me curious too now...
Can you share a little more on your experience with the Bio-Actif salt?
It's my understanding that it's essentially the Pro-Reef salt with carbon dosing compounds added to it. I can see this helping/feeding corals in a higher nutrient tank ... but worry it might cause problems if used in low nutrient tanks.
Would appreciate insights on it from someone who's used it.
BTW - OP, I've been running Carbo-Calcium (powdered mixed into RODI) for about 6 weeks now. Haven't seen any real signs of build up on the end of the dosing lines yet.
