Unfortunately it is not working. From what I have read water changes and trying to attain a clean tank doesn't work for dinos.

Water changes and blowing off the rocks having low phosphates and low nitrates appears to be not working for you.

Adding more fish, as you have seen is a problem in itself. You need to quarantine for at least a month assuming everything goes well. I have been trying to add more fish for over 6 months to my tank unsuccessfully can't get them past the quarantine stage/ type of fish I want not available when I want it.

Over feeding can help dirty up your water, stop blowing off the rocks if you are not exporting the dinos as you are just moving them around and spreading them.

Like I said before what worked for me is a micron filter helps remove smaller suspended particles and a UV sterilizer on a low flow rate to kill any dinos after I have blown off the rocks.

INNOVATIVE MARINE AUQASHIELD UV STERILIZER (9 WATT) is around 60 bucks.

I have some KNO3 and Potassium Phosphate you can have for free if you wants some. You know where I live.

You need to have measurable amounts of phosphate and nitrate.
