I am still having trouble with the 240. I have decided to make some fundamental changes. Both my returns and overflow are maxed out. I have ordered a new overflow to be made by Modular Marine in a custom size of 20 x 3 x 7 to be glued to the back glass. I have 2 return pumps each pushing water through a 1 inch line to a single 3/4 inch bulkhead. It is killing the flow so I am going to split them and add a 1 inch over the top return to each. I will just glue a tee into the spa flex behind the tank. I am hoping this lets me get the dirt out of the tank and into the sump to be removed. Right now I stir it up and it settles right back down. The way it is now 2 x 2000gph pumps is only getting me 1000gph through the sump.
If I ever have another 240 made for me(LOL) I will know to have more that 2 x 3/4 inch return holes drilled.
The sulfur denitrator took off and was foaming like crazy but I screwed up and increased the flow to much and nerfed it.
I am looking for 8 liters an hour/200ml in 90 seconds. 48 gallons a day processed would be like doing a 10% water change every day.
The LaCl is keeping the nitrates under 0.1 by dosing 1.2ml into the skimmer every hour. I am not pushing it. The amount sequestered in the tank should come down over time.
Reducing the phosphates has brought on a huge cyano boom. I am trying to avoid using Chemiclean. I want to see what happens when the nitrates fall.
