As some of you may know, I've been fighting a massive algae problem for the past year or so, to no avail.
I have a 10g nano, which is constantly covered in green hair algae all over the rock and sand (glass not so much of a problem). A lot is removed during my PWC
's (20% every 2 weeks), but then grows back within a matter of days.
My tank readings are, and always have been, very good: 0-5ppm nitrates, 0 phosphates (although this could be a false negative reading from the algae consuming all phosphates). I have a large amount of LR
for filtration, as well as a small internal filter which has activated carbon, RowaPhos and PURA filtration pads in it.
I get my RO
water from my LFS
, which tests 0 phosphates and nitrates, so it's not that. I also feed very sparingly once a day (usually flake food, and sometimes frozen good quality food which is drained, and always fully consumed quickly). My photo-period is also short, at around 5 hours per day.
I've also tried changing my lights to see if that helped, but it didn't.
Basically, I've tried everything, and am now completely stuck.
I want to upgrade my tank to a bigger one in order to be able to put more livestock in, and more flexibility with lighting to add some corals etc., but I'd only do the upgrade if I could ensure I can basically start fresh again and make sure this time that I stop the algae before it starts.
The new tank will be 25-30g, and I'll probably be moving my current live rock across, and will be adding a bigger filter. I'd like to know the following:-
1. I've never had a protein skimmer; if I add one to the new tank, will this help to keep algae under control?
2. I currently don't have any powerheads in my 10g tank as there isn't really room, so the only flow in the tank is the filter spraybar across the surface. If I add some powerheads to the new tank to create good flow, will this also help to keep algae to a minimum?
3. I'd much rather get my RO
from my LFS
as it's more convenient for me, and it does read 0 phosphates/nitrates (and suitable TDS
). But, would producing my own RO
make better quality water, and therefore be less contributive to the algae problem?
Any help appreciated. I had a cleanup crew in there, but it was way too much for them to deal with, so I need to find out what I can do with the new tank before I start, to ensure I don't get this same problem again.
