MARINA Longstone A/Stone 6 B/Pack

Good bubble flow

Absolutely great airstone, just make sure you have a pump that is strong enough to push the air through and that it is level in the tank otherwise bubbles will only appear on one end of the airstone. 5/5 for this product my fishes love playing in it and its a great price too! ☺️

Not a very even spread of bubbles and one of the stones was just gurgling to start with. I removed the stones and boiled them for twenty minutes and now they’re much better and I have a good even spread of fine bubbles

Does the job as seen in my photo. Make sure you know your air pump outlet limits before choosing size. My air pump (Love fish medium size pump) is suitable for a 16cm stone/bubble wall maximum, I wanted a nice curtain of bubbles so I chose the 15cm size stone. Give it a soak for a few minutes and rinse off any debris before use just to be safe. Very easy to install and it sinks which is great, I worried about having to tie it down.

Bought this with high expectation after reading reviews but have been left disappointed as the first third of the air stone is the only part of it that produces bubbles. Never had an air stone do this before. It is useful as it sits nicely on the bottom of the tank, but as I said, disappointed that it only partially produces bubbles. My fish love love love their bubbles so I have ordered a different brand in hope that this one will do the job.

I ordered 2 of these for my tank, one works perfectly, the other, less than half of the stone blows bubbles. I updated my pump and still no difference. Very dissappointing.

For the price you really can’t go wrong! Works as it should.

Lots of bubbles in the tank. Happy fish

Har två luftsten en i var sida av akvariet. Den ena stenen får luft genom 1m långt rostfritt rör begravt under sanden. På grund av metallens tyngd flyter inte röret upp från den fina sanden, utan är dolt. Tror inte fisk mår dåligt av metallen då jag använder kraftigt Zeolitfilter.

J'en ai acheté deux ! Ils sont grabds et ont un bon rapport qualité prix. très satisfaite de mon achat;

Ok so maybe it was the air stone that made the bubbles, but either way bubbles were made. I was a little disappointed that it didn't do any other tricks but I suppose if you are going to do something, do it well. This air stone did. It made lots of bubbles (with the assistance of a whisper air pump)

Hace su función, esta bien 👍

as other reviewers have posted, only half the stone seems to put out bubbles.
