6095, 6105 and sand...

[hobbzz]

I'm setting up a deep blue 80g rimless, and will be going with either 1 6095 and 1 6105 with wide flow housing, or 2 6105's both with the wide flow housing. The dimensions of the tank are 48x24x16. I'm debating on a shallow sand bed or barebottom. The tank will be mostly sps but will also have a decent amount of lps and zoas, palys etc. If I go with a 2-3" sandbed, will I be asking for trouble in the form of a sandstorm? Also what do you think about the 6095 + 6105 vs 2 6105's? I currently have a bb tank, and I like the look and ability for high flow (100-120 turnover for me right now) but really miss the shrimp/goby combo and jawfish. TIA.

In the beginning you may have a fair amount movement ... how much and how long will depend on grain size but it should die down as bacteria colonizes the sand.

That being said I would consider a pair of 6095s instead of the 6105s as I think they will be plenty of flow as GPH is about the same is a 6105 with a 18v jumper and will visually look alot better in that size tank.

^ +1. I have two 6105's in a 180 (72 x 24 x 24) and I am running them with the 18v jumper at 55% and wide flow nozzles. Plenty of flow. "If it was me", I would go with the 6095"s for a 4' tank. They put out plenty of flow.

So the 6095 would still move a fair amount of water 3' away? It would definitely be nice to have two smaller ones. I was thinking of going with one 6105 aimed up higher for parts of the tank with sps, and the 6095 down lower for lps and such. But if the 95's would do the trick that would ne nice. On the other hand, if I got the 6105's I could always turn them down and have more flow for future growth or tank upgrades. Anyone know what the 95's do with the 18 and 24 volt jumpers? I've only been able to find numbers on the 6105's with jumpers.

You could always run the 6105 with the 12v jumper and wide nozzle. Also the 6105's have a flow control knob that can reduce the flow also.

The 6095's will definitely do the job, at 12V the flow is roughly half at full power, at 18 it is about 2/3rds.
