A little disclaimer before I post the latest pics. On the bottle of Waste-Away, there is a disclaimer stating they recommend starting with a 1/2 dose. Then, late in the instructions, it states to use 10 mL per 10 gallons of system water. On the instruction card I got this the Cyano Treatment Package, it says to start with a 1/4 dose and increase with each dosage. My tank is 40 gallons and my sump holds about 5 gallons.
However, after starting this thread, I did read on other websites that people who dosed 1/2 or full doses had some losses and horrible clouding (bacterial blooms) of the water. So, I decided to proceed with a LOT of caution. Last night I only dosed 5 mL of Waste-Away. Tomorrow will be the second dose and I will increase it to 10 mL.
That said, I think the Re-Fresh/Waste-Away combo is starting to work. Here are some pics this morning. For comparison, before I started dosing, almost everything would be covered in Cyano in the morning and it would slowly go away as the day progressed. These pics were taken about 6:15 AM this morning.
Still have some Cyano on the rock and sand but, not nearly as much as I have in the past. Sorry about the crappy pics. The only tank lights on are the moon lights and I had the basement light on. So, it was hard to get decent pics.
