When figuring out what materials to use for an algae scrubber, don't neglect considering strings... sometimes they can hold on to the most growth, because they are narrow and light can get to all sides of them.

A big benefit of natural algal filtration is that it grow pods, naturally. So not only does the algae absorb ammonia, nitrite, nitrate, phosphate, CO2 and metals, but copepods and amphipods get lots of natural food (that's what they eat - algae) so they multiply a lot. And they are protected...

With more people wanting to use natural filtration for their tanks, we are going to look at the two main types of units that you can put on your system: Chaeto reactors (or "algae reactors") and algae turf scrubbers (ATS). We won’t be looking at refugiums however, since those have mostly a...

We are building a campaign to reach the general non-reefing people to show then the benefits of algae. There are no product pics yet, but the description is there so let's see if anyone here has any suggestions for editing: https://www.kickstarter.com/projects/santa-monica/1517121823?token=b5a68bdc

Using Seaweed to get rid of nuisance algae in your aquarium or pond, part 1 One of the neat things about nature is that it's had a long time to figure things out. Especially under water. Here, nature has figured out how to reduce all the "nutrients" to very low values, and also how to feed...

Looking to find out what most people's back compartments are on their nano's. If you could post what the size in the pic is, and your model of nano, that would be great:

Many people, when they use algae scrubbers for the first time, get worried when more (not less) algae starts to grow on their rocks. It seems really strange, especially when nitrate and phosphate have gone lower than before. What is happening is that phosphate is coming out of the rocks...

Have had two of the Ecoxotic Marine 48" for a while now, so posting here to see if anyone else uses them.

3D printing your aquarium parts For those of you serious DIY folks, you may be interested in how you can make your own plastic aquarium parts by printing them on a 3D printer. Just this year, costs for the 3D printers have dropped to under $500 USD for a pre-built one, and under $200 USD for a...

Looking for FW RS folks who are running scrubbers.

My 90gal tall (30") euro bowfront is about 7 1/2 years old and has 1/2" acrylic. It has about a 1/4" warpage in several directions that you can measure and see. One section of the top, where it connects to the overflow, is about 1.5" wide and has cracked apart, leaving about a 1/8" gap extending...

Lowest cost and easiest way to eliminate green hair, bubble, turf and slime algae from your aquarium (hopefully permanently). This new test version of the algae scrubber is much easier to build than the waterfall version (the Mega Powerful one), and is perfect for nano's. This new scrubber...

Need to replace my 2 X 150 mh + 100 actinic, and looking for recommendations. Would like: 300 to 500 watts of power used. 48" wide Ability to turn the light inwards is nice. Ability to turn the light towards the back, so does not blind you. Ability to move the lights up or back, to get...

50 to 100 one-inch monte cap coral frags, taking over tank, will break off frags in trade for other corals. Tell me what you have. Must come to Santa Monica.

...specifically, ballasts for T5HO bulbs. Do they slowly lower their power to the bulbs, or do they stay constant until the ballast goes bad.

Anyone know the smallest most-compact 2-bulb 24" T5HO fixture? The smallest one I knew of was the Current Nova Extreme 2X24 watt T5HO at 24 X 4.25 X 2" (model 1124), but the new versions are bigger (too big).
