How can I stabilize my ph (major fluctuations)

Anyone have a thread on how to make a waterfall and how big of pump for each tote

Use your imagination bud....

Is one water fall that size big enough for a 17 gal res or should I make multiple

one per tub. you'll have plenty of Dissolved O2 that way.

I have two drains coming off the table plus this runaway line total of three waterfalls.

Another white drain on the other side for the other side of the table

the more the merrier! the only downside would be increased heat by more pumps but the chiller negates that.

Where did you get that style of tubing at? Looks like CC but that stuff is stupid expensive.

If his pump is in the water couldn't he just run a venturi and some 1/4 tubing out the top?
Those things really blast out the bubbles.

Would something with multiple streams create more DO than a single waterfall
Something like this picture

Yeah but if your not running a filter it might clog.
Check this out. You dont have to build one. You just buy a nozzle that hooks to end of your pump. You run a 1/4 air line off that up out of the water so it can suck air.

Only one pump. No chiller .

Im in canada and i run bennies. Southern ag. Gff

Each table has two drains going back to the res plus one runaway line in the res

Its a 396 eco plus pump.

3/4 feed line that ends in a loop, and has small triangles cut out for feed holes into each net pot

Those 396's put the danners to shame for what they cost.

So I got home last night started to drain my res to sterilize everything . Once 90% if the water was removed I could see how much hydrotron partials were in the bottom. I decided to RIP everything b.c apart and rinse and sterilize every thing the new pump filter was horrible. Also where I glued the air stones with the marine glue was starting to mold . Hooked everything back up added cal-mag and 1/2 strength nutes and set ph at 5.3 woke up this morning ph is at 5.4 .so thanks everyone for there input and help

Okay problem is back set ph to 5.3 last night and when I woke up 6 hours later 7.6 ... I removed the cooler and I'm flushing it out with h202 for 24 hr . This is starting to piss me off . I think I'm going to re start my grow when I figure it out and start fresh but need to figure it out first
