When should I start EI?
I've been plowing through EI threads for an hour, but I'm still confused as to when I should start my EI dosing and if it matters when I switch over to RODI.
I'm just two weeks into tank -- Aqua Soil Amazonia II substrate with HC plugs, lots of CO2 (no livestock). The HC looks like it is responding well (some pearling) and no algae so far. I'm trying to stay proactive and give the HC the best chance to spread and out compete algae.
Still cycling with the Aqua Soil, doing 25% water changes with tap water every other day. Tap is hard and base. Condition it for chlorine, but have not been adding anything else. Out of the tap: PH 8.5 – 9.0, Ammonia 0, Nitrite 0, Nitrate 2.0, KH 10, GH 10, TDS 280. After 2 days in the tank: PH 6.5, Ammonia 4.0 (sometimes 8.0), 0.5, Nitrate 3.0, KH 2, GH 4, TDS 300.
My plan is to start auto dosing EI. Also planning to switch to RODI water (I have a good 5-stage left over from reef tank w new membrane, media) and reconstitute it vs. mixing with tap.
My question is, what should the timing of both of those changes be?
