Uv. And still hair algae

i added a uv sterilizer about 2.5 weeks ago and brushed almost all the hair algae off my rock with tooth brush(new one) and for some reason i cant still get rid of my pesky hair algae i have tried everything got water tested and everything is perfect, could it be comming from the water on my ro/di tds reads 14 is that enough to keed H/A growing should i replace all my ro filters and di resin,
Ps. its not my lights new bulbs, im using a trickle filter with rock and blue balls

 

ro/di could be causing it 14 tds is just a tad bit to much. Anything over 1 is bad. Also do you have a p04 reactor you might also have phosphates present.

 

+1, ro/di should be 0 tds. Do you not test your own water? It could be very well that your LFS is telling you your water is perfect when it's really not. Happens.
I would say first thing, get your own test kits. Pay particular attention to nitrates and phosphates.
How is the flow in the tank?

 

hello Kedron

The UV will help with anything free floating, but does not help with any secured algae
do you have a Phosphate reactor or some other means of using GFO in your system

I had a similar problem some time ago and used Rhowphos , ( there are other equally as good products, I know ) combined with the manual removal as your doing and eventually
I was able to remove and starve the GHA out of existance

I agree, this seems really high for TDS coming out of an RO/DI. How long has it been since you changed your media?

Regarding the algae growth, my money is on phosphates in our water. Consider getting a phosphate test kit and checking both your tank and your RO/DI water.

 

Going through the same thing with the hair algae. Here is what i found out. Even though all your parameters are good and your using good water, if the bulbs are old, more red spectrum is entering the tank. Could that be your problem. I know its mine...;D

 

well i do test my own water i went to 3 different LFS and they all said the same thing its getting better but i think you guys are right its my ro/di filters i will just change all of them its a 6stage unit i was thinking bout adding another di stage will this help with water quality and the halides are only few month old could it be my actinic light i haven changed those yet they are pretty old

 

oh and i have 760 watts on this 55 gal tank is that too much, and a korila 3, and a 4 in the tank

 

Not sure. I bought a used fixture w/ X amount of months/yrs on the bulbs. Thought i would be lucky. Guess not. Gonna replace all bulbs in a month or so.

 

How many watts does it take to fry an egg? J/K......
