Separate names with a comma.
Yes, but if that were to be true we would be talking about an algae scrubber screen so big it would be nearly unthinkable. I think too much credit...
Simple solution to 'one off' nitrate problems, full water changes. If you know the system is just at its limits and can't reduce nitrates, but has...
Floyd, it looks like there will be a sump under the tank, so I don't think there needs to be a 23' drain for that purpose. The only thing I see...
Tebo: My recommendation was using the assumption that you were going to use some type of optics. Either way, the ratio is still what I would...
This link/video pretty much sums it up for me. End of that topic on here now. ;) Back to answering LED display light questions. :)...
Kerry: Optics are a very important factor. 60 degree optics will give you 3x the output per LED, plus adds a lot of penetration power. So yes,...
Sorry for the delay, been a busy weekend. To answer the questions in order: 1. Problems with too much 455nm = photo saturation/inhibition in...
Personally, I am not a fan of the 2:1 RB:W ratio because it puts way to much 455nm (royal blue) light into a tank, which causes problems. I would...
That article doesn't seem to take 'spectrum' into account. Once you take that into account, and design a light around it things become much more...
The problem with those lights, as you discovered, is by custering LEDs in a PAR38 bulb it creates really bright 'hot spots' in the center and then...
Need to see some PAR readings to judge the intensity. Pics are the worst method for others to tell by, especially pictures of LED lit tanks. I use...
Your call, if it were me I wouldn't use one for several reasons. Risk of overflowing (depending on the model), noise, size of the pump in the...
I have seen way to many successful 20G tanks and below do fantastic with no filtration at all, just weekly water changes, powerhead, heater, and...
For most things on a sub 500G tank, yes, that would be true. One of my tanks doesn't have an ATO and I am bad about topping off, I regularly toss...
I don't think it is a theory when many reputable places have done studies and shown without a doubt phosphate levels under most circumstances, as...
Wait a minute.. Cree LEDs from China CAN be just as bad as generic LEDs from there. The reason being is Cree only sells them the diodes, it is up...
Memories.. I had the same Voltron set, won it as a raffle prize selling coupon books for little league. I even kept mine in the box (I believe it...
Yes, an overflow box does both of those things, but as far as gas exchange, I would guess it does 1-5% of what a skimmer can do. If you think of...
Personally, I would drill the tank. If you don't want pipes out the back you can always drill the bottom and make an overflow box to house the...
That is the reason I have pretty much always had my skimmer running on 1 tank. For a year I used it without the cup just to see if it made any...
