[quote=three90s&125sump;1586919]A touch more on flow... I have 2 K4s modded with maxi mod sure flow mod kits and I also have 2 tunze 6100 streams. If money is a factor I highly recommend doing the sureflow mod on the K4s. For about 50 bucks (if you shop around) you can have 90 percent of the flow of a 300 dollar 6100. Not to mention the K4s have nicer mounting equipment, are less obtrusive and cheaper to operate as well. They are just not controlable. I have 2 6100s and 2 sureflow modded K4s in my 40 cube. Total turn over rate with all pumps at full power is 300X. 30X turn over is a good start but I recommend more. I would shoot for 80X - 100X turnover. I average 225X with controllers active. 4 modded K4s will get you to 80X turnover. This is all directly related to filtration via agressive skimming.


Uh... What's your substrate?


I definatly recommend doing several large (30%) water changes with some fresh and balanced ASW. Salinity - 35ppt, Ca - 420, KH - 9d and Mg - 1300. Be sure to mix the fresh ASW for 24 hours with a good pump and plenty of fresh air. It looks like you have been dosing and your conservative proportionality of your water has been thrown off. Even if its not that bad, several good water changes will only help.



Do you mean the Maxi-Jet Sure Flow mod kits? Bascially I just change the impeller? They are running for $15.00 so I wonder if I am looking at the right thing?

[three90s&125sump]

That's the one. You change only the impeller.

The shaft and magnet from the K4 are used. Don't loose the little plastic piece behind the magnet on the K4.

Here is a pic of the box...

I realizethat the Tunzes are outrageously expensive, but their programming and flow characteristices are superior to the PH's listed above. This is especially true for large systems (>125 USG ~ 500 L). If I had to do it again, I would still go with the Tunzes, even at their cost, as they can also run on 8-24 volts DC (solar panel, 12v battery, etc) in an emergency, even though I have a backup generatorfor the huse and tanks. With the controller, they are superior for stony coral flow in closed systems.

Well, Tom, your bank account might be as fat as your brain but mine is not

But I agree, the controlability of the Tunzes is very nice

I say I would do it again, yet i still have not broken down and bought another 6100 or equivlent...[IMG]file:///C:/Users/tdwyatt/Pictures/smilies/brain%20hurts.gif[/IMG]
