After reading your last few posts and thinking about your algae trouble. I believe an unbalance on your nitrate-phosphate-carbon is most likely what's going on. .
API PO4 test scale is not good to detect low levels of phosphates. Starts at 0 and jumps to 0.25 and colors are almost similar. I use Red Sea and sometimes double check my value using Hanna.
The cube I recommend is X-port Bio or you can use Siporax. This is just in case if you choose to replace the rubble (optional but most likely unneeded). Rock rubble is fine to use too, but this media has much more surface area for bacteria to colonize.
At this point you can blow you rocks, syphon the algae out, keep doing your WC using as source of 0 TDS RO/DI water and let your system balance out and mature.
Thanks for all the advice, I buy my water from marine warehouse. I will continue to do weekly or bi-weekly water changes and try and get a Red Sea test kit. Should i start using something like fuel, reef energy a/b or Kents nano a/b ?
