I would suggest a properly sized UV. You could even go the next step and do a blackout for 24-36 hours to get the dinos into the water better. Proro often won't swim without a blackout. If you hadn't already come across this, it is worth a read IMO. (But I wrote it so...)I'm currently battling prorocentrum in my sandbed, dosing silicates, bacteria, and phyto, and finally getting some diatoms!
Now the concern is I have an outbreak on my rockwork with coolia...
Moving forward what should I treat first? I do have a UV but I'm concerned that using it may disrupt my diatom population but I also want to tackle the coolia.. any advice how to proceed is much appreciated!
