Flow not enough?

[Tate]

I have a 90 gallon fowlr currently cycling and a bunch of idk came from my wet dry into the DT and some is settling on the bottom. Only In certain places though. I thought my phs were in good places but maybe not they are two maxi jet 1200s 295 gph

Are they the maxijets that are convertible from powerhead to circulation mode? If so run them in circ mode. You should get about 1200gph each.

 

[Tate]

How do you convert them??

 

[Dav3]

They should have 2 different impellers and other different hardware for the two modes if they are the convertible kind.

 

[Tate]

No they aren't convertible

 

[Dav3]

Well then you should probably replace them or just add more powerheads. Currently you only have about 6.5x turn over. Not sure what is recommended for FOWLR but I know it's more than that.

2 x 1500 gph power heads IMO.

 

[Tate]

Probably going to get a 600gph and 400gph

 

[mr_X]

Suit yourself.

I run two 1400gph koralias in my 90g fowlr and that is the perfect flow for that tank/

How? How does that not disrupt your sandbed? I have trouble with my two 295s stirring sand up lol

running a wp40 and a Evo750 on my 125 and i need to replace my evo

Your sand looks brand new. it will stop blowing around eventually.

It's just a matter of proper placement is all.

I aim mine upwards a bit facing the front glass. Causes a nice chaotic flow and keeps my sandbed perfectly clean.

 

[Tate]

Are they on the side glass or the back glass

 

[carey]

I keep one on either side of the tank.

 

[Tate]

Both facing front glass or one facing front the other one facing the back

 

[carey]

This might help

 

[Tate]

Oh okay it looks good does the flow need to specifically go to a certain point? Like to the overflow or something

 

[carey]

Nope, I just tinker with my placement until I get nothing lingering on the sandbed without disturbing the sand. You pretty much just want constant flow in every nook and cranny of the tank. All tanks are of course different due to rockwork but just play with it til you find the sweet spot.
