Oh, the algae needs light! I took the light that was over the sump out when I put the protein skimmer in, and didn't think about the algae. There is no light there now, though it does get some light from the window, and the room is equipped with daylight lights. That's probably not enough though, is it? I guess I'll have to get a small light to hang over it or something. If I put it in the tank, they would eat it, right?

I haven't given up on those inline heaters being installed. I've just given up for today. :lol:

Good news, the Fluval has stopped seeping. :mrgreen:

Ah, nice. This is all good to hear... yeah, the algae need light :lol: And I don't think any of your fish would bother the algae too much, if you did decide to grow it in the display... BUT, now you need a bit of info about macroalgae.

Macros are mostly seasonal in nature, and are known to go 'sexual', meaning that the plant releases male and female gametes that come together to form new plants. When they do this, they empty all of their cytoplasm (the squishy stuff inside), which if it happens in a tank will have 2 effects... the first is that the water will cloud, like milky white. The second is that all that cytoplasm will fuel a bacterial bloom (sort of like dumping a large canister of flake food into a tank, as I read on a thread here somewhere) which will devour all of the dissolved oxygen in the water, choking off anything else in the tank.

People that keep macros in a fuge with 24/7 lighting and occasional heavy pruning seem to experience this less, though it's not a common occurance even in marine planted tanks. People that have experienced this have attributed it to a sudden change in the environment and a lack of nutrients, together, but the evidence is sort of anecdotal.

Just know, about this particular algae... it can be invasive on your rock, though pruning it regularly will probably keep it from taking over. If you do decide to plant your FOWLR, there's an excellent resource for information about this sort of thing... www.marineplantedtanks.com

Oh, lastly (there's always something more I want to say :lol:) you don't need any fancy lights for the macro in your fuge, a decent wattage CFL will be fine. Just leave it on all the time.

The daylight bulbs in your basement are not actual spectrum. i used to work for Phillips lighting. they are simply an imitation. i would not want to rely on those for anything but sterile looking white/blue lighting in your home.

I was thinking the regular CFL twist bulbs, the 3500 K ones. People have had success with them when just growing macroalgae.

I use the daylight, phillips CFL's for OT tank at present. (6500 deg K) They grow cheato and feather caulerpa very well.
Also have some sps and lps in there as well, waiting for my 120 gal build to be finished. Trumpet, digitata and montipora cap. They are very near the surface. Not ideal, they are growing though, not fast, but they definately are not dying.

I wouldn't doubt that, but many reefers have been using "daylight" or "6500K" bulbs for refugiums very successfully and they sure look a hell of a lot better than "soft white" CF bulbs.

I did a little more research and the ones I'm talking about are the 'daylight' ones. I thought they might the 'soft white' 3500K ones but I was wrong. Though I'm sure those will grow algae just as well.
