Filtration products etc. ?s

[JJIM]

Anyone have experiences with the below products? Are they good for filtration, replacement, waste of money, etc?

1. Seachem Purigen
2. SEA-LAB #28 Automatic Replenisher
3. Seachem Purigen
4. CupriSorb

Thanks!

Purigen is useful, especially in nano's that do not run skimmers.

The Sea-Lab 28 is loaded with ridiculous promises and I think it has no use in a reef tank.

Purigen is a fine way to export organic matter. I'm not convinced it is better than GAC, but it may bind a slightly different assortment of organics and can be complimentary to GAC (so using both can be OK).

Cuprisorb is a fine way to deal with excess copper, but I wouldn't normally use it unless you had reason to be concerned about copper.

Randy, I believe you have concerns here that I am not aware of? I thought perhaps this would be a good maintenance mechanism for keeping heavy metals low.

 

[Randy Holmes-Farley]

I do not know what it actually is, so I don't have any special concerns. Just possibly an unneeded expense.

Thanks.

Does the SL-28 keep a system buffered and replace some lost/depleated minerals? Or, are these simply erroneous claims?

JJIM,
Use two part solution (as found on bulkreefsupply, etc) or kalk, the SL-28 sounds like snake oil to me.

The sea-lab dissolves and adds something, but since it cannot know what the alkalinity is or whether the tank needs those trace elements, it is just adding a bunch of stuff in an uncontrolled manner.

What do you do when you go on vacation and your unable to add the Ca or Alk that you might supplement had you been there? I guess this is why I as about the SL-28, not really for a indefinite solution whether home or away. I do dose kalk with my top off water currently.

The SeaLab might act as some sort of dosing, but since its dissolution rate is uncontrolled, you have no way of knowing what it's going to do. If you search around, there's at least one old thread in which I was diagnosing some problems one person had with it. It ended up in the garbage.

Putting the limewater in an automatic top off system is the answer there. I've had one such setup on my system for 15 years. It runs by itself for about 1-2 months, depending on the season. For other methods, a two pat can be put on a timed dosing pump, and CaCO3/CO2 reactors generally run unatttended.

Thanks guys!

Happy Reefing.

Does the CupriSorb help with the removal of unwanted metals in a reef and with removal of copper after dosing for, say, marine ich? Does it in fact help with both, or just for the latter?

 

[Randy Holmes-Farley]

I do not know what it is and so do not know what metals, if any, it removes aside from its claims to remove copper.
