Brown algae slime problem

[pablo mero]

Hi people . I need your advice on on this algae problem. Its been with me now for the last 2 months and sreems to be getting more apparent. 2 weeks ago i changed 50% of water as my nitrates were through the roof. I though this might have solved the problem. At present my nitrates =0.5 pH=8.2 PO4= 0 KH=10.2 Ammonia=0 I have a 100gal reef tank up and running approx 1 year. the algae is a brown colour with tiny bubbles all over the sand and live rock. Any info please please.:help:

what is your bioload?
do you feed heavily?
how old are your bulbs and what types of lighting?
what K rating are your bulbs?
are you using tap water? RO? DI? RODI?
how often are you doing water changes and what percentage each time?

in addition to that water parameters would help as well.

sounds like the feeding might be a bit much and because frozen foods contain phosphates the heavy feeding may be escalating the phosphates in ur tank. do u have a phosphate test?

[Fishieness]

thats also a lot of large fish for a 100 gallon
would also like to know your parameters

[Germanman]

yea those two regals will outgrow it...mine will sadly have to go soon to her 350 gallon home away from me...

I did a water test earlier today with PO4 profi test by Salifert reading was clear 0 mg/L

strange....i use the same test and its always accurate...maybe reduce the feeding and add a skimmer if u dont have one. also maybe increase the amount of water u take out in changes.

[pablo mero]

all fish are small at present and im in the process (planning stages) of building a 350 gallon glass has been ordered for tank and sump. i hope to have everything ready in a couple of months and then transfere all

[Germanman]

well best of luck with that sounds fun:)

[pablo mero]

Thanks so much friends for your help. I have a built in skimmer at present Working of a wooden air stone . My pump crashed on the deltec skimmer waiting for a replacment ordered.

May I also suggest cutting your "lights on" time. I've had a huge problem with Dino algae but my phosphates were high but cutting my lights down helped a huge amount.

well i see just about all points on this Cyano bacteria A.K.A. "slime algae" have been covered but one thing.

Filtration, Without the proper filtration or current in the tank Cyano bacteria loves to spawn. Try adding another powerhead or two and see if that helps. however i would wait a month or 2 after you stop feeding the tank 4 times a day, thats WAY to much feeding. Try cutting back to 1 maybe 2 feedings a day. Fish dont get 4 meals a day in the wild, might be lucky to get 3 to be honest with you.

Also i believe it was Germanman that said Frozen foods contain phosphates and he is right on with that. Sadly most frozen foods are that way.

thats why i use a phosphate removing resin in my tank. calvary is right good advice there!
