Another sump question?

[Rscomia]

Do you prefer high flow or low flow through your sump and why?

 

[carey]

In my 125g I am most likely running way too much flow but I tend to like it. Might not be the best idea with a refugium which i didn't take into account when i set up my sump. LOL

 

[Rscomia]

I tend to run high flow through mine as well but does to much flow not allow your sump to process all the water before going back to the dt?

This all depends on whats in your sump.A fuge is for growing pods and other critters and should be a slower flow,A sump with a macro algae like chaeto does better in a high flow.

I have a fuge which now also houses my skimmer do to the lack of space I have It seems to me that the higher flow rate through it is across the top though

This is due to the make up of the sump

Yes I realized this I didnt have a skimmer when I first built mine so i didnt plan a in sump skimmer also the biggest tank I can fit under mine is a 29 gallon which doesnt allow alot of room either

If you want a bit more scattered flow in the sump put a small powerhead in there to mix up the flow.

 

[Rscomia]

What advantages am i gonna gain with more scattered flow?

 

[David S]

If you look in my profile there's a photo of a sump with low flow and it shows(the cloudy part) the water flowing over the fuge part of the sump

 

[Rscomia]

That is basically the same as mine except my skimmer had to go in the middle How many gph goes through it and what size display tank

 

[mr_X]

I don't think it matters. Just don't have it so slow that you have standing water in the corners.

 

[Rscomia]

What if your skimmer doesnt process as much water as what flows through your sump?

 

[mr_X]

Your skimmer is only processing what gph the pump hooked to it is pulling. If water misses it, don't worry, it's not going far. It will come back around promptly..lol.

 

[Rscomia]

So basically all the water is going to get skimmed Will it make my skimmer more efficient if I slow the flow down?

 

[mr_X]

No. it will not.

 

[Rscomia]

Well maybe you can help me determine what is fueling my green hair algae My thoughts with the flow and making my skimmer more efficient was to help I have a reef octopus nw 150 I have tried everything I have read so far I use ro/di water, I have alot of flow in my tank 2 1300 gph wavemakers plus my return pump, I do weekly water changes of at least 10% My lights are on 6 hours a day My phosphates test 0 but that is because the gha is using them up The only thing I have done that has actually helped any is vodka dosing but all it seems to do is slow the growth and I know this is not right cause im not eliminating the source of the fuel I am lost on where to go next

 

[mr_X]

How often and how much are you feeding?

 

[Rscomia]

I feed once a day a small pinch and then about every 3 days I feed my sun coral and put a piece of seaweed in for my tangs

 

[mr_X]

Maybe it's too much. I feed a tank i've been maintaining 2 times a week. I've been doing this for a long time now and the fish are fat.
have you checked the T.D.S. of your R.O.D.I. water recently? When the filters need changing, they get less efficient.
