Blue plus puts our same PAR as 14K daylight....im after a blue looking tank so cant do too many white or yellow bulbs.

Sticking with 4 Blue Plus / 2 14K white / 1 Actinic and 1 Purple As recommended by Grim Reefer

Hi. Can anyone help me decide on good bulb combination for my reef. I have a 8x24w T5HO overhead but cant settle on decent bulb combination for colour and growth of my SPS/LPS I have lots of SPS frags on frag rack 2" from surface. 1 torch and frogspawn coral . 1 BTA hosted by 2 clowns...

at 1023 now so will steadily add salt each night to get up 1024

I accidently changed my salinity from 1022 to 1024 with a water change. Is it best to leave it now, as trying to keep changing it will just add extra stress to the fish?? I have clownfish and fire goby but both seem unaffected so far ( 20 mins later ) and did feed when I put some flakes in...

Urm i dont consider 175l tank to be nano. I have a 25 litre tank and that is a nano and I almost have same stocking level as you I have fire fish, clown and damsel with 2 crabs and several soft corals. You could add alot more fish to that tank, just make sure you have sufficient filtration...

Most agree with that my 5g has over 3KG live rock and still could do more...... more the better as it really helps with removing nitrates for biological filtration

Remember its really PAR that matters not Watts per gallon. My 5 gallon has such small volume of what and low water depth that my 15watt light is very effective

You were told wrong. I run a 15w PC light on my 5g nano tank and I sustain all soft corals easily. I think 18w would be fine on your tank for basic corals.

On my 5g I run some GFO in my small internal filter and a 900l/h koralia power head. Thats it. Had a small skimmer but saw no difference with or without. If anything since I have removed it i now have 0.5ppm nitrates at most

but if 2 inches in near full grown then he is already full size so ok?

Sorry yeh just to confirm he is an ocellaris clownfish not percula.

I have fire goby in there. He seems happy enough for last 5 months and all parameters ok. At one stage I had 4 fish in this tank

hes barely 2 inches long

Just get confused. Why some people say no fish in my tank yet I have what is considered a large bioload and still have low nitrates. You can stock as heavy as you want in my eyes, just the heavier you go the more work to maintain parameters?

orange tint is most likely diatoms which use silicates not phosphate or nitrate. Try running some GFO to clear the silicates and it should go.

my 4 gallon pico has 1 clownfish, 1 fire goby, 2 crabs and several low light corals. All ok with zero algae and 0.03 p04 and only 2ppm nitrate

Same, main ones you need after you have cycled etc is Salifert for Phosphate and Nitrate... keep them at zero and all is good

Nope both my D&D and Salifert test kit show nitrate under 1ppm and have only seen it as high as 2ppm. I dose vodka and have lots of live rock so assume they are using it up aswell as the xenia. I have zero algae and lots of pink coralline.

Hi. I am a little confused with some comments I always here from people regarding bioload on a Nano. I have a 25 litre nano with the following stocking 1 x percula clownfish 1 x fire fish goby 1 x red leg hermit 1 x blue hermit Some Xenia / Polyps / Zoas and live rock. I am now 5 months...

14 gallon tank and my drop checker is lime green and yellowish in morning. I run co2 24/7 at about 1bps.

How long do you think a 95gram bottle of co2 running at around 1-2 bps will last?

nope... just 2x 2ltr bottles changed weekly

Well i have gone to 8 hours for now and im dosing excel to clear BBA. Always happens when my co2 goes and I forget to check bottle weekly :(

Can plants survive with just a 6 hour photperiod indefinetly?
