Yes - AlgaeFix (Marine) was the product we tried. It seemed to have had SOME effect on the algae! The hair algae started to discolor, and "die off" - which... allowed me to pull and pry off the hair algae from the rocks (or take the rocks out and scrub them with a brush).
The problem was this fix was only a temporary band aid and the hair algae eventually grew back.
I used to run the lights for 8-9 hours, but am now running them for 6-7 hours.
The room the tank is in does get a lot of sunlight. We have french doors that face the east! So every morning & afternoon sunlight literally pours into the room. It only directly hits the tank at certain times of the year, but the tank does still receive a lot of INDIRECT sunlight. I wonder if that might be the major cause of the algae problem?
I have a good feeling if I do these three things:
1) Slowly remove the bio balls
2) During the weekly pad removal, also clean out the 2 sponges
3) Construct a poster board tri-fold cover to completely BLOCK the fish tank while we're at work mon-fri (no sun AT ALL) can now enter the tank - except on the weekends
I'm hoping by doing these 3 things will significantly help our algae problems.
I also think by running the algae fix excessively may have been a contributing cause for our flame angel to get sick. I think that product is best used for just a 2-3 weeks (but we were doing it week... after week). It does say "invertebrate safe".
I also have a feeling the dirty sponges and bio balls may be contributing to spikes of nitrate of 30-40ppm. From my understanding, crabs and snails don't do well with these levels... would the community agree? So our cleanup crew typically starts dying off within a few weeks! Is this normal, or is this because we get nitrate spikes until the next PCW?
Assuming the removal of the bio balls (and ensuring the sponges are cleaned) I'm hoping the tank would now only hit a max. of 10... maybe 15 ppm
BEFORE the PWC
. I hope the community can please tell me this is a reasonable expectation for a 60gal tank with 5-6 fish.
