how much food?

[Patriot76]

i have a minor cyano algae problem right now also. was wondering if it was due to over feeding. i feed two cubes of Hikari mysis, brine, or spirulina brine once a day. then some ocean nutrition flakes in the evening. plus a couple sheets of San Francisco Bay Brand Seaweed every other day or so.

i have 14 fish-

3 tangs (all large)- purple, yellow, kole
7 anthias- 2 bartletts, 5 lyretails
2 true percs
1 purple psuedo
1 scooter blenny

is this too much food? it is all gone within 30 seconds

tank is 180g

Temp 77
Salinity mS 53.3
Ph 8.0
Nitrates 10-20
Nitrites 0
Calcium 400
Ammonia 0
Phos 0

Bill, it must be Sayreville water because we have a major outbreak of cyano as well!

hmmm, my in-line tds meter is reading 0 out of my ro/di filter. i should get a hanna hand held to test my reservoir. i thought maybe i was b/c i upgraded my my bulbs from 10k to 12k, but that was about a month ago and its only gotten worse since then. its not covering any LR yet, just the sand bed and on the a couple of the power heads. maybe i should add more water movement to the bottom of the tank to stop it from settling on the sandbed

In a more typical system, considering the reading you have for nitrate, I'd say you were overfeeding, BUT you have those Anthias in there, and they do require a constant supply of food. You really can't get around that.

Since your going to need to feed, and thus add more nitrates and phosphates to the system, you need to do something to remove them. You should be able to do one or more of the following -

Add a refugium to grow macro algae, possible with a DSB, if you don't already have a refugium on your system. Make it rather large, not a hang on tank thing.

Add some easily grown corals to consume some of the excess. Looks nice, limited effect.

Water changes, a 25% water change is a 25% reduction in nitrate and phosphate.

Add a denitrification filter. I always fome them to be a pain to keep regulated, and in some cased fed.

i have a 55g fuge with a dsb & macro algae.

i do a 45g water change once a month

i am going to try using seachem de-nitrate in my canister filter along with carbon

I have the same problem. moved a powerhead closer to the bottom and most of it is gone already. starting neozeo system.only been 2 days of just the liquids for now I'll be starting the rocks soon
