not enough rock

[jeddy576]

What would happen if there was not enough rock in a tank?

depends on what you mean? .. not like you can't run a tank with no rock in it.. but with reefs and a lot of fish live rock just helps filter your water and keep things balanced.

i started out my 110 with 25lbs of dead base rock and slowly worked up to what i have now
if your tank is only 20g 20lbs is good are you running a skimmer
and if you have less rock and no skimmer keep up with water changes and don't over feed
is there a problem with your tank or were you just wandering

it all depends what type of tank your trying to run......maybe try being a little more specific with the question..and we can help ya

I have a lot of brown algae growing on the sand. i have a skimmer but i have no idea how much rock i have. i have added some and taken some out and added more. i do water changes like every 2-3 weeks. I feed once a day but not much and run my lights for 9 hours a day. Ive tried turning my lights off for 3 days but it keeps coming back

weak processing. Show us a photo. We can tell a lot from that.

Give tank size, brand of skimmer, type of pumps, etc, plus what you're keeping.
AND your current chemistry tests.

i have a 20L with a bakpak skimmer a bio wheel with just the filter pad and a mj1200. for fish all i have is a firefish. i have a frogspawn, some zoas, zenia, mushrooms, leather, plate coral, and a sun coral.
nitrate 0
nitrite 0
ammonia 0
ph 8.1
i dont have a test for phosphates

there is where you problem most likely lies. If you could test for them I would bet they would be high.

Testing for them is trickey since most test kits are very hard to read. I would remove the filter pad and run some carbon and phosphate removing media in that biowheel and see if it clears up

fuge for phos... grow the algae you want so you dont grow the algae you dont want..
