Getting crystal clear water?
Competitions are coming up and fotosessions are due. What can be troublesome is not having that crystal clear water right when "You" want it.
For example, my tank is usually crystal clear, but sometimes small particles cloud the water. It might be PMDD, fishfood etc. Point is, When Ive planned a photosession I want a backup so the water is crystal clear no matter what.
Using an extra filter with wool filter the days before is ok. But what about chemicals? Some company sell "crystal clear" remedys. How do they work, what do they do!?
Do they inflict on nutrients?
