Mh Hqi

[Mcain4]

I was wondering if any one knows which way is up on the hqi bulbs? is the medal thing closest to the tank or is the nipple soppose to be?

[The Grim Reefer]

Joe Berger(SP?) did a test and concluded there was no "right way". I have heard people make a case for nipple up to prevent material from settling in the indentation. That makes a little sense but I have 250 watt HQI's which can only mount one way and they are made both nipple up and down, go figure.

ok so basically it doesnt matter.... Also kent makes this chemical to clear up tank water i am running a reef setup anyone have any objections to there product?

[Reefland]

All the DE bulbs I have used only insert into the sockets one way, and due to this some bulbs have the nipple up and others facing down.

On the chemicals...I OBJECT! Do not use "chemicals" to try to cure your tank of anything. First, what is not clear about the water?

[Mcain4]

the water is slightly cloudy the rocks have a slight yellowness to them. My substrate is white so im assuming that the green algae on the rocks from when i left my lights on for two days is still lingering. I am running a current usa 150 watt 10k with 2 t5 24 watt tinics. I am not running a skimmer. 40 gallion uniquarium what would be the best way to clear up the algae on the rocks and the water?

[Reefland]

A skimmer would be a big help, you could also trying running some good activated carbon.

yah im just short on cash right now and cant afford to get the aquac remora which is what i want so im kinda in a pickle. as for the carbon ill look into it thx..

[Reefland]

Yeah try to put some carbon in a mesh bag and place it in a high flow, pass through area in your tank (where lots of water will pass through it). This should help polish the water.

I know the additive you're talking about. If you have cloudy water it will help to settle out the particals but in your case I think the skimmer and carbon are a better solution. If you can't afford the Remora take a look at Coralife's supper skimmer. Less $$$ and a good performer from the early reports.
