daily water changes in large tank

[clekchau]

thanks for the explaination ixthys

my question is, how do you compensate for the evaporation in the lower tank filled with mixed saltwater?

 

[Chrisrush]

I think that the lower tank is sealed, therefore, no evaporation occurs.

 

[clekchau]

oh ok that makes sense if it is sealed.

hey chris, what do you think about incorporating the constant water change system to my design?

 

[Chrisrush]

Shouldn't be that difficult, especially if we follow the design that Ixthys has stated.

Ixthys do you have any pictures of your setup? I would like to see how you have it plumbed.

thanks for the feed back!!!!! I am planning on setting mine up in a similar fashion. other than the reef filler pump mentioned above, does anyone else have any exp with other systems/pumps ( ie.. aqua-medics reef doser, or the litermeter III ect.) Is back siphoning even a concern with these if power goes out???

 

[clekchau]

here is the article that ixhys was referring to, a good read

Hey, that's the one!! Nice post.

 

[Ixthys]

Here's a pic during installation:

water tanks

The small blue object on the shelf (left side of image) is the pump. The 2 water tanks are on the far right side (the top one is way up high and hard to see in the photo). You can also see the ro/di unit.

Hope that helps!

clekchau, thanks for finding that study on water changes....I had seen it some time ago and had forgotten about it...pretty informative. goes to show there are alot of ways to do things and no right or wrong way!! Ixthys, thanks for the feed back and posting your pics. I'm still trying to decide which pump to go with for the water changes. any pros/cons that you know of??? there are some price diffs between them. any thoughts on siphoning issues? (I think your resevoir is up high)

 

[Ixthys]

The pump I use has an antisiphon feature.

 

[clekchau]

i am seriously considering this type of setup and using the same pump ixthys is using, are there other pumps that do the same thing out there?

I use a slightly differant system for daily waterchanges:

1. Bulkhead at top third of sump goes to floor drain
2. Turn off return pump, when water reaches this level this is the high point.
3. Turn return pump on, this is the level you set your autotopoff pump to maintain
4. Every morning aquacontroller add .5% new water to the system.
5. Water circulates for 10 minutes
6. Aquacontroller cuts the return pump off.
7. .5% water goes to the floor drain.
8. Aquacontroller turns return back on after 5 minutes.

Easy, cheap, reliable.

The Spectrapure Litermeter III was designed to do this.

 

[brent waldron]

hey tacocat, do you use or have any exp with the litermeter?? its pretty pricey....any feed back on this unit?

 

[brent waldron]

dandy, I like the sounds of your set up. where did you pick up your aqua controler??

 

[Avast Marine]

Heres some action pictures .

Aquacontroller is a Neptune from Premium Aquatics. I bought it mainly for temperature and Ph control but, there are a bunch of geeky things you can do with them.

 

[brent waldron]

dandy, thanks for the info. looks like a great set up. I apprec your time and feedback!!!!!!!!

 

[clekchau]

dandy, good stuff
