I even have two fans blowing on my water fall scrubber and I cannot really say I see any type of equilibrium as I hoped to when this method was first discussed a couple years ago or so. In theory I...

If its (the returned carbon) anything like DOC then the bacteria will consume it and so will coral.

Ok, so we are the same thinking. In the end the ALK (carbon) is used by algae. I am never low on CA seeing I dose saturated Kalk.

I agree with Floyd on the LED distance, its to close.

Why do you say algae does not use (keeps) any ALK? What would it consume if it does not use (keep) a carbon source. Maybe I am not fallowing what you mean????

I can dose 2-4 quarts of saturated (with vinegar) lime water (Home made Kalkwasser) into my 40G breeder every day since my scrubber was changed over to LEDs when we all started testing them with the...

I am sure I have not read every thread since I have been away but, just my 2 cents.
My horizontal scrubber in my pod tank has always been a semi floating deal (half of the horizontal ramp is in the...

I do what Floyd does as well. I just keep the dKH as level as I can. I keep my Alk between 8.5-9ish and my pH is always at about 8 on my monthly or bi-monthly (this translates to when ever I get...

Even when I dosed 100ml vinegar per gallon I never really had a bloom. A month ago my water had a slight white haze to it for a few hours and I wondered if it was the bacteria but it was before I...

I normally dose at least 50ml of vinegar and 2 tps of calcuim hydroxide (kalk, lime powder, pickling powder) per gallon. I dose about a gallon of this per day to my 40G. I have done this for a long...

I dose the vinegar a bit heavy and dont have any bacteria that you can see. I am about 200ml per 3 gallons instead of 150ml like most do.

Thats a nice little guide!!!!!

This led stuff is all over the road. I have about a 36" (6x6 roughly) screen and run 5 3 watt leds per side (one of the 5 is blue 445nm) driven at 680mA though diffusers. I get huge growth like this...

How do your corals go without being Hungary with a skimmer? Do you target feed them? If your scrubber is working as intended your skimmer should not have dark color as far as I know. Granted I have...

I have seen a many on the internet bash them. Most talk about and rant you still have to do water changes and I tell them I do but its only about 10% changes every few+ months or so. I encourage...

That is absolutely what I have observed. When I rinse the screen in the tank before I scrap it there are many many many more pods that come off the horizontal screen then the waterfall screens. I...

Yes, me too. One of my favorite on my list.
Yes, I have tons of pods in the 150G. I have kept my other Mandarin in a 10G for years. I have a 10G tank dedicated to raising/breeding pods. In my 10G...

Say Hello To My NEW Little Friend!!! These tuned out real good for Phone Pics!!

Please dont!!!!!! This is a very open forum and NO FLAMING goes on here!!!! Let us know what you think. Its been common knowledge about softies and LPS in a scrubber tank but folks like Me and others...

FW algae grows like that. Its like slime, no real roots that really grab on. With FW you MUST have a super rough screen. I ran my FW with only a two hour off time in the end and didnt get yellow...

Red are the trick for sure but, I have seen warm white grow algae but not like the 660nm red do. You might try reducing your display light hours and or longer scrubber hours. IMO I would upgrade to...

I have yellow, orange, and pink in my scrubber tanks with no issues and a ton of pineapple sponges.

I will paste the code they sent me:
Hi Kerry,

Happy Holidays! If you didn’t get what you wanted for Christmas we have just the solution for you: we’re bringing back our Black Friday sale from...

I have a smaller tank with a lot of LED power over the the DT and it out powered my scrubber (Yep, algae started to grow in the display about 3 weeks after set-up). I have since changed the DT light...

I have only used 450nm and 445nm so I am not sure. I would have to think it would still be ok.

For giggles I have my 10G set-up pulsing right now. I just put a driver on the LED's that to big so it does the safety thing and flashes. I have been doing this for about two weeks and there seems to...

I have used hundreds of these from this eBay guy in Ca so you dont have a long wait time either because he stocks them....

I am not sure if this is right but I always assumed that 2-3 frozen cubes would be about SM one cube if the water was removed. Since I have gone LED's with Red and Blue I dont even worry about what I...

I do consume huge amounts of Alk, to the tune of a gallon a day to a 40G tank every day for 6 days and sometimes I can skip the 7th or just a small 1/2G top off. It works for me!!!!! I call it my...

I bought the reflector type that was only about half that for a confined build a while ago. The largest diameter is about 4"-5" or so.

Same as Garf here, I just dose Kalk about 98% of the time. Occasionally I will dose just sodium bicarb (baking soda) if the Ca is over 550PPM or Calcium chloride if the Alk does not need adjusting or...

Most MH bulbs are more toward the blue spectrum and you really want to be into the red more. They also use a lot more energy for the output. CFL bulbs are easier to because you can get all the light...

Thats looking real good.

You have great growth going there!!!

Thought I would share a few pics from the 40G.

I gave 150G UAS more then an honest go Rick. It grew 3D algae 2+" thick on each side on two 5x5 screens, one on each side of the HOB filter. I have never had a WAS grow so much 3D algae as I did in...

I have had both and IMHO I have not had good luck with the UAS in a large tank. It works great on my 10G but I was unable to get good results with it on my 150G even though it grew handfuls of algae....

I really think there is a ton of potential here but I have not moved forward with it yet.

Photosynthesis can be completed in as little time of about 1ms. PWM modulation testing has been done for more then a few decades. Before electronic circuits they used wheels with slits cut in them...

You could move the light back about an inch or cut back the hours by "one". Try either of those for a week and see what happens and adjust as needed, you could also increase the flow if thats an...

You can pulse the light on and off over 1000 times a second and photosynthesis keeps up. You need a longer off cycle then the on cycle though as it builds the product quicker then it distributes it....

Looking good Sir!

Its the extra blue LED!!! I cannot believe how well they compliment the growth of the red LED's

I would like to share a pic of my First Two Weeks Growth!! I rubbed the algae backwards to get it to lift up and place a 1/2" pvc pipe behind for length comparison. Both sides look the same and there...

I have thought about trying 8 on with maybe 1-2 hours off.

NO!! I use four red and one blue. You have to have the red as these are the base light and the blue just helps out.

Looking good a2c!! I am with SM on this one too!! Get a good week or two before you do anything drastic so you have good info on where you have been and where you go after making changes so you know...

I have not noticed a swing in Alk whether Mg is 1100 or 1500. Maybe its just my system?? I also dose a Gallon of saturated Kalk (with vinegar) a day to a 40G tank.

I like to use photobucket. They have a nice image link you can copy and paste. The biggest thing you will notice is the Alk will go down more when you start getting a lot of algae growth. Its crazy...

My brother has one like that on his 50G/55G (its one or the other). Its a Marinland bio wheel filter with a screen in its place. It was cleaned last night so its not showing any algae on it....
