Hog 1 Help

[Wanch]

Hi, I've recently started my marine set up (120 litres).

It's been running for about 4 weeks and I've seen no growth in the Hog.

Lights have been on for 12 hours per day and the cloth kept over it. I've now had a pretty bad outbreak of what I believe is green Cyanobacteria.

Should the Hog be using the nutrients the Cyanobacteria would need to grow? Do you have any recommendations to combat the outbreak and get the Hog up and running please?

I'm not using a protein skimmer as I believed that it would not be needed with a scrubber.

Thanks

Welcome from the UK.

The cloth has been on only part of the LEDs, so that part of it is uncovered, correct?

Hi...no I've had it all covered as per the label on the cloth. Should it only be half?

[SantaMonica]

Yes I had to re-word the paper to say partly cover, not fully cover. So pull the cover down 2" and run for 18 hours and it should start coloring up in a week.

[Wanch]

Thanks, I will try that and see if it works

[Wanch]

Ok so I've done what you advised above for just over a week now.

Please see the progress below. What do you think

Are you sure the light is on at all?

A pic of it installed would help.

[Wanch]

The lights are on for 18 hours a day? Pic below of its installed

[SantaMonica]

Where is the cloth? It should be covering 3/4 of the lights.

[Wanch]

Cloth is covering half as you previously advised

Not really clear from the pic

[SantaMonica]

Maybe you have it going vertically. Cover more, only leave 1" open.

[Wanch]

The cloth is going horizontally, should it be vertical?

[SantaMonica]

Does not matter but you do need to reduce the light more.

[Wanch]

Hi, it's been two weeks since your last advise...please see the pic below of how it's coming on.

What would you say to do next? Thanks

[SantaMonica]

The part on the right that has brown: is that the covered or un-covered part?

[Wanch]

The brown part is the uncovered section

[SantaMonica]

Ok then uncover another third, and run for 7 days at 18 hours light a day.

A couple of questions.

1. How much air are you running through the HOG1? I can't see any bubbles from your picture, so I wonder if you don't have enough.

2. How much are you feeding daily. If you are not feeding very much, you won't get much growth.

As for the cyano bacteria, usually this is caused by poor water quality, poor lighting or not enough circulation in your tank.

What are your tank chemistry readings? What are the Nitrite, Nitrate, Ph and Phosphate readings?

[Wanch]

Hi, in response to your questions.

1. You can see any bubbles as I turned it off to take the picture. Air flow is sufficent using the recomended tetra pump
2. 1 cube per day
3. Water quality is perfect, all reading zero and PH is 8.2

It's been a week since my last post so here is the latest picture:

The long piece from left to right was mainly off the aquarium glass

[SantaMonica]

Switch the cloth, so that the top end is uncovered instead of the bottom end.

[Wanch]

Hi, update since the advice above:

http://i1380.photobucket.com/albums/ah171/gary815/A9E70C3B-E831-45D3-80B0-0AAEA3D77F77_zpsnu0uv9yu.jpg (http://s1380.photobucket.com/user/gary815/media/A9E70C3B-E831-45D3-80B0-0AAEA3D77F77_zpsnu0uv9yu.jpg.html)

The top half is the section that has been uncovered. What do you recommend next please?

[SantaMonica]

Ok better.

Slide it sideways, to a new piece of glass.

Clean all the holes to make sure they are not clogged, but don't clean the growth surfaces.

Uncover more, so that only 1/3 is covered with the cloth, and let it go another 7 days before a full cleaning.

[Wanch]

I've done the above thanks.

Now it starting to grow, do you think the algae in the display tank will ease up?

[SantaMonica]

We'll see soon.
