Thanks for the advice bro.. couple of ideas..
1. reduce length of overflow
2. Redo cover to extend into media area to prevent splashes
3. Reduce pump power ... but that will reduce my current in dt..
so will be adding another wavemaker after cycling
Paiseh, didn't write clearly.
Ordered rodi water so tested tds but shocked to see such a high number. That was when I found out it they deliver nsw instead.
Haiz...
