Mine is showing good results already after 7 days. The 150Watt MH light is soon to be replaced with GU10 LEDs. However the sump glass has proven stable from the heat generated from the MH light being 1inch away. :Cheers:

Well I have about 400g of LR assisting to brace the plastic mesh until I have time to perfect the balance of the mesh :frustrat:

I am trying a bit of live rock too. Seems to be doing the same job so far

That is why my question generated. Certain types of glass, ie tempered glass can with stand heat, others can't. I have no idea what sump glass would of been made of. But anyway, I am looking at replacing that light with one recommended, and perhaps try and fit the MH light into the tank some...

Seeing your great results, I think I might ditch the 150Watt MH light and get a 13watt light.

It is a 150Watt metal halide light shinning about 1inch from the glass. The glass does get warm after a few hours. Just that if it is a risk, I would rather not do it, then do it and the sump glass cracks, tank drains and everything dies.. I am leading to believe it won't do any harm...

Okay without your sarcasm, it is not "shinning" the light that "hurts" the glass, it is the fact that a light gives off heat, which can heat up the glass, with the water pressure in the sump could create a weak spot in the pane of glass. Why else was tempered glass made.

Am I just confused then? This algae scrubber concept works with lights shinning directly onto the sump glass around 1inch away. Surely whether the constant heat from the lighting stressing the glass would of been considered? I have had mine running for 3 days now around 14 hours a day cycles...

Hi, I have a DIY algae scrubber in my sump. I have a 150Watt bulb 1 inch away from the glass. Will the light on +-18hours a day cause damage to the glass via the heat it is creating, ie stressed glass or something?

I set this up the weekend. My only concern is that with 150Watt of light directly on to the sump glass, may it cause it to stress and eventually crack?

Still no luck on revealing the awaited design??

Any update???? I am dying to DIY this in my tank! Current status - no scrubber!

Wow I would not of thought that would happen! Good info!

I got some furry/hairy mushrooms last week. If they do detatched, what is stopping them getting chopped up in the fans?? Would they poison the water?

Hi, When my inverts shred, is it best that I take the shell out or does leaving it in the tank do no harm? Thanks
