New Algae Scrubber newbie

ok will order the 100w then as it has an ac plug. will keep you posted

 

I confirmed by asking on amazon and they said the one i ordered has an ac plug. So will keep you posted. thanks

 

I got 2 of those light, and they are really bright and strong. But on doing one tweak with the plumbing i messed something up, so had to go to the Eheim compact 1000 which is very weak for that setup. Right now flow is very weak just a trickle. Will order another pump soon (this one)

Give me your take please

thanks

 

i am afraid one of the screens will dry out coz of the low flow, what do you think turbo?

 

I am honestlyundecided between the DCP 4000 or DCP 5000, inclined to 5000 but afraid it may be a tad strong. They say it can be ramped starting from 30% power. Let me know please

 

- yes dedicated for the scrubber at lowest setting. Honestly i am also looking for it as a backup to my return as well (running 400 waveline as return). just afraid jebao 4000 or 5000 will be too strong
- another option was just looking at is rio pump 1700 for $35. at 1 foot of head and like 2 elbows i should be getting like 580-600 gph. i think that should be ok for total 21" of screen length (for the two screens). How is the noise level on the rio pumps?

 

the 1700 at 3ft (12") gives out 442gph. so given the two screen have 21" of length, flow is 442gph/21"=21gph/inch. it looks ok'ish given the new rule of thumb of 25gph per inch you stated.
If i move to rio 2100, the 442gph number goes up to 472gph (at the same 3ft/12"), so it does not look that different to "me"

 

Can i use the rio 1700 or 2100 with 1/2" ID Vinyl tubing (my plumbing for scrubber is designed for 1/2")? checking and it says only used with 3/4" !!

 

got it, thanks. i called several sellers about rio 1700 and 2100 today and it turns out there is no 1/2" fixture attachment included, confirming your statement. My threaded end has only 1/2" and that is the only size i could find to fit the female threaded 3/4".

what do you think of this pump? Jebao as well

The horizontal pipe with slot for the screen is .75 inches, the connection to the pump is vinyl .5 inches id. Only point of attachment to pump is .5 inches rest of scrubber plumbing is .75 inches

 

Just tested nitrates and are still at 40ppm. So frustrated and don't know what to do. Thinking ripping and cleaning the whole sump.

 

will see, just got a new jebao fountain pump

and it is working nice. also got a new CF grow light (a third one) for in between the pipes (the inner screens). will try 2 screens for a while and then evaluate. thx
