OK, do you have any live rock in the tank? Can you describe the "built-in filter", what is inside the filter (filter media...).... I have a Boyu TL-550. Approx 130l, with built in filter rated at 720l/h. I have added a powerhead rated at 2400l/h. It comes with 2 compact flourescent type lamps (10000k), with each lamp having one blue and one white tube. It also has a protein skimmer & uv steriliser.
That's a good start, but unless it's very light and porous I would guess you might need some more... Rather than go by weight, I prefer to talk volume - you will ultimately want about 30% - 50% of your tank's volume to be LR (could be less if you have a deep sand bed (DSB) and/or a refugium...)I have approximately 15kg of live rock in the tank.
I thought so... and you most likely had to pay good money for the bio balls, ceramic noodles and UV steriliser This filtration system would be OK for a fish-only set-up, but in the long run the sponges, bio-balls and ceramic noodles will only result in an elevated nitrate level, which will cause unnecessary nuisance algae problems, and which is also detrimental to your coral's health.The filter takes up the whole of the back of the tank, and has 4 compartments. In the 1st is some sponges, and a protein skimmer, the 2nd some more sponge, a few bio balls, and 2 socks of ceramic noodles, the 3rd has the heater, and the 4th houses the pump & a uv steriliser.
Did they give you the actual reading of the phosphate, and define what they consider to be "acceptable" and "good"? And did they (or you...) test for ammonia and nitrites. With a "0" nitrate reading I would suspect that the tank is still cycling, and that you could still have ammonium and/or nitrites. Having added the fish, etc. today, I would also advise that you continue to do daily ammonium and nitrite tests until you have "0" readings for both these parameters for at least one week.I went to the fish shops today, and they tested nitrates = 0, phosphates were present but at an acceptable level, salinity was good.
Yes, with NOTHINGReef Maniac, do you have a suggestion with what to replace the bio balls etc with ?
