Update :
Tank builder coming Saturday to install 4 new gate valves (Different ) brand - spears ...
One of the NDS has a bad stem and leaking...
I’ve got all the Ecotech pumps and wave makers programmed and dialed in, the all come to a slow barley turning enough to prevent siphon at 630am for feeding and ramping up to full power by 730. I must say the two mp40’s churn up and waste and leftover food off the gravel bed. I run them at 100% after feeding to get the leftovers eaten or put in the W/D. “Feed mode” finally works after I calibrated the pumps...
The auto water change seems ok, I’ve been watching it daily for a week, I pump out 25g every 12 hours... nitrates seem to hover around 5ppm.
I’m going to implement some of wolfmans plumbing suggestions after tank builder has completed his job...
Need to manage all the components too... got them sitting on egg crate...
